Answer:
<u><em>definition;</em></u>
enzymes are protein that catalyze speed up the biochemical reactions and are not changed during the reaction . the molecules at which enzyme work are called <em>substrate </em> and enzymes convert them into different molecules called products.
<em><u>benefits of enzyme in digestion ;</u></em>
enzyme lower the activation energy in several ways. they may alter the shape of substrate and reduce the requirement of activation energy . enzyme may also lower activation energy by bringing substrate in correct orientation to react . enzyme break down <em>carbohydrates, lipids and proteins </em>which are component of human food .In digestion larger molecules are broken into smaller molecules like amino acids ,simple sugars ,fatty acid ,vitamins ,salts and water to provide to cells. these molecules are a part of larger molecules like protein ,polysaccharids and lipids . enzymes like amylaze, lypase ,salivary amylase, pepsin ; it is a very strong protein digesting enzyme it is released in its inactive form pepsinogen which is converted into pepsin with the help of H-C-L hydrochloric acid it takes part in digestion in stomach
Answer:
b. 80g
Explanation:
Three cycles of PCR would produce 3 doublings of the amount of DNA.
Cycle 1: 10x2 = 20pg
Cycle 2: 20x2 = 40pg
Cycle 3: 40x2 = 80pg
This can also be worked out for large cycle numbers by final mass = starting mass x 2ⁿ, where n is the number of cycles.
A human starts with” 1 “cell and by the time they are an adult, they have “ 50 trillion “ cells
Answer:Polymers are large molecules composed of many similar smaller molecules linked together. The individual smaller molecules are called monomers. ... In the molecular world, the small subunits that ultimately link together to form larger molecules are called monomers, which literallymeans "single unit" (mono = one).
Explanation:
Answer:
Mitochondria.
Reactants of cellular respiration are glucose and oxygen.
Explanation:
Mitochondria is the location of cellular respiration where glucose is broken down in the presence of oxygen into energy in the form of ATP. When a glucose molecule is broken down with the help of oxygen, it produces energy, carbondioxide gas which is a waste material and water. There are three products of cellular respiration such as energy, carbondioxide and water. Energy is used by the organism in different activities while carbondioxide gas and water are removed from body through breathing. Using of glucose by mitochondria and converted into energy in the form of ATP is the energy flow.
