What is enzyme?Enzymes are biological catalysts that are almost always proteins. It accelerates a specific chemical reaction in the cell. The enzyme is not destroyed during the reaction and is reused.
Enzymes are classified into six functional classes based on the type of reaction they are used to catalyze. Hydrolases, oxidoreductases, lyases, transferases, ligases, and isomerases are the six types of enzymes.
Sucrase accelerates hydrolysis by breaking the bonds between sucrose and releasing fructose and glucose subunits.
The arrows in the diagram above indicate that this is a cycle reaction. As a result, sucrase is recycled in the subsequent chemical reaction. Moreover, no modifications to the way sucrase is depicted have been made.
Thus, this way sucrase is not used up during the chemical reaction.

explain the disadvantage in terms of energy loss when humans eat beef rather than legumes
Answer:
Katha Ko Bajja Muchi Ko Chora
The main disadvantage in terms of energy loss when humans eat beef rather than legumes is the inefficiency of energy transfer.
When humans consume beef, they are consuming meat from animals that have themselves consumed plant-based foods. However, energy is lost at each step of the food chain. Plants capture energy from the sun through photosynthesis and convert it into organic compounds.
When animals consume plants, only a fraction of that energy is transferred to the animal's tissues, as some is used for metabolic processes, movement, and other functions.
Therefore, when humans consume beef, they are indirectly obtaining energy from plants but at a much lower efficiency. If humans were to consume plant-based foods directly, such as legumes, they would bypass the energy loss that occurs in the conversion of plant energy to animal energy. Legumes are protein-rich plant sources that can provide comparable amounts of nutrients and energy without the same level of energy loss.
By opting for legumes instead of beef, humans can have a more efficient and sustainable use of energy resources, reducing the environmental impact associated with livestock production and utilizing plant-based sources more directly.

How is the Nucleus like a brain?
Answer:
The nucleus contains the DNA of the cell which can be thought of as the brain of the cell.
The nucleus responds to stimuli via receptors which can be primary or secondary. Basically, an external ligand (hormone, protein, nutrient, etc) binds to the surface receptor of a cell, this, in turn, causes the receptor to release a messenger (most of the time circular AMP (cAMP)) which binds to a secondary receptor which is either directly inside the nucleus or on the nuclear envelope. Finally. the portion of the DNA which is responsible for the protein to respond to the ligand is activated and begins transcription.
The activated DNA section (gene) produces mRNA which in turn produces a protein in response to the ligand.
On top of this, the entire cell cycle of rest, growth, and division is controlled by the nucleus.

The pizza that you ate for lunch is being digested. Summarize what happens to it in your stomach.
Answer:
This is the one.. that i did when i was schooling.. I still hv it thank fully..
Hope it help..!!
Explanation:
The correct answer about the digestion in the stomach of the pizza one eats is - The pizza is churned, mixing with digestive enzymes and gastric acid.
Digestion of the food takes place in the alimentary canal or digestive system. In this organ system different organs are used to digest different food molecules and absorbs them.
Let assume you ate a pizza slice in which it moves through the alimentary canal. it begins from the mouth and ends at colon through the esophagus, stomach, small intestine, large intestine.
Mouth: here pizza is chewed with our teeth, broken down and mixed with our saliva. Saliva also has an enzyme, called amylase, to help break down carbohydrates. This called bolus that moves to the esophagus to stomach.Stomach: a pouch shape organ where the pizza mixes it with gastric juice and digestive enzymes to digest protein by pepsin. The food or pizza now called the Chyme that moves to small intestine.Small intestine: receiving the pizza in the small intestine, pancreatic juices and bile from the gallbladder mixed with it and digest the pizza.The nutrients from the chyme (the pizza) absorbed in the small intestine.Thus, the correct answer is - The pizza is churned, mixing with digestive enzymes and gastric acid.

The DNA sequence AGGCTTCGCGAAGGTAAC would code for the sequence of 6 amino acids.
True
False
Answer:
True
Explanation:
Amino acids are coded from the DNA sequence in groups of three bases, that is, three bases (three letter codes) also called codon codes for (or specifies) an Amino acid.
in the above DNA sequence each of the prospective 6 Amino acids will each require a triplet of bases. Thus, the simple calculation of 6×3 yields 18. Thus we need at least 18 bases in our DNA sequence, barring stop codon, to code for Amino acids.
Counting, the above DNA sequence contains 18 bases exactly.

include a player holding there arm/shoulder, one unable to put weight on their foot/leg, one holding the area around the
buttucks/upper thigh, one is holding the side of his head, and one is holding there stomach/side. Knowing what you know now
about the bones, muscles and joints discuss in detail, what bones, muscles or joints are in these areas and what type of
diagnostic technique could be used?
Answer:
HI :)
Explanation:
What Are Bones and What Do They Do?
Bones provide support for our bodies and help form our shape. Although they're very light, bones are strong enough to support our entire weight.
Bones also protect the organs in our bodies. The skull protects the brain and forms the shape of the face. The spinal cord, a pathway for messages between the brain and the body, is protected by the backbone, or spinal column. The ribs form a cage that shelters the heart and lungs, and the pelvis helps protect the bladder, part of the intestines, and in women, the reproductive organs.
Bones are made up of a framework of a protein called collagen , with a mineral called calcium phosphate that makes the framework hard and strong. Bones store calcium and release some into the bloodstream when it's needed by other parts of the body. The amounts of certain vitamins and minerals that you eat, especially vitamin D and calcium, directly affect how much calcium is stored in the bones.
Bones are made up of two types of bone tissues:
Compact bone is the solid, hard outside part of the bone. It looks like ivory and is extremely strong. Holes and channels run through it, carrying blood vessels and nerves.
Cancellous (pronounced: KAN-suh-lus) bone, which looks like a sponge, is inside compact bone. It is made up of a mesh-like network of tiny pieces of bone called trabeculae (pronounced: truh-BEH-kyoo-lee). This is where bone marrow is found.
In this soft bone is where most of the body's blood cells are made. The bone marrow contains stem cells, which produce the body's red blood cells and platelets, and some types of white blood cells. Red blood cells carry oxygen to the body's tissues, and platelets help with blood clotting when someone has a cut or wound. White blood cells help the body fight infection.
Bones are fastened to other bones by long, fibrous straps called ligaments (pronounced: LIG-uh-mentz). Cartilage (pronounced: KAR-tul-ij), a flexible, rubbery substance in our joints, supports bones and protects them where they rub against each other.
How Do Bones Grow?
The bones of kids and young teens are smaller than those of adults and contain "growing zones" called growth plates. These plates consist of multiplying cartilage cells that grow in length, and then change into hard, mineralized bone. These growth plates are easy to spot on an X-ray. Because girls mature at an earlier age than boys, their growth plates change into hard bone at an earlier age.
Bone-building continues throughout life, as a body constantly renews and reshapes the bones' living tissue. Bone contains three types of cells:
osteoblasts (pronounced: AHS-tee-uh-blastz), which make new bone and help repair damage
osteocytes (pronounced: AHS-tee-o-sites), mature bone cells which help continue new born formation
osteoclasts (pronounced: AHS-tee-o-klasts), which break down bone and help to sculpt and shape it
What Are Muscles and What Do They Do?
Muscles pull on the joints, allowing us to move. They also help the body do such things as chewing food and then moving it through the digestive system.
Even when we sit perfectly still, muscles throughout the body are constantly moving. Muscles help the heart beat, the chest rise and fall during breathing, and blood vessels regulate the pressure and flow of blood. When we smile and talk, muscles help us communicate, and when we exercise, they help us stay physically fit and healthy.
Humans have three different kinds of muscle:
Skeletal muscle is attached by cord-like tendons to bone, such as in the legs, arms, and face. Skeletal muscles are called striated (pronounced: STRY-ay-ted) because they are made up of fibers that have horizontal stripes when viewed under a microscope. These muscles help hold the skeleton together, give the body shape, and help it with everyday movements (known as voluntary muscles because you can control their movement). They can contract (shorten or tighten) quickly and powerfully, but they tire easily.
Smooth, or involuntary, muscle is also made of fibers, but this type of muscle looks smooth, not striated. We can't consciously control our smooth muscles; rather, they're controlled by the nervous system automatically (which is why they're also called involuntary). Examples of smooth muscles are the walls of the stomach and intestines, which help break up food and move it through the digestive system. Smooth muscle is also found in the walls of blood vessels, where it squeezes the stream of blood flowing through the vessels to help maintain blood pressure. Smooth muscles take longer to contract than skeletal muscles do, but they can stay contracted for a long time because they don't tire easily.
Cardiac muscle is found in the heart. The walls of the heart's chambers are composed almost entirely of muscle fibers. Cardiac muscle is also an involuntary type of muscle. Its rhythmic, powerful contractions force blood out of the heart as it beats.
