Why does the chemical digestion of proteins start in the stomach?
The stomach secretes an enzyme called pepsin that works best in acidic environments, breaking down proteins into smaller peptides. This acidic environment, created by hydrochloric acid, helps denature proteins, making them more accessible to pepsin. This initial breakdown of proteins in the stomach prepares them for further digestion in the small intestine.
When can infants start testing proteins in their diet?
Infants can start testing proteins in their diet around 6 months of age, when they are developmentally ready to digest and tolerate them. It is important to introduce proteins gradually and monitor for any signs of allergies or intolerances.
How proteins are digested?
Proteins are digested by proteasees (enzymes) in the digestive system. Trypsin, peps, chymotrypsis are the proteases of stomach that start digesting proteins in to peptides. Enteropeptidases further digest them to small peptides and finally amino acids.
Where does carbohydrates begin?
Carbohydrate digestion begins in the mouth, where saliva and chewing both start to digest those kinds of foods.Mouth, saliva contains the enzyme amylase which breaks down sugars (carbohydrates)
How does temperature help control enzymes?
Proteins change shape as temperatures change. Because so much of an enzyme's activity is based on its shape, temperature changes can mess up the process and the enzyme won't work. High enough temperatures will cause the enzyme to denature and have its structure start to break up.

Why will salivary amylase start digesting the chips in a human mouth but not the chicken?
Salivary amylase is an enzyme that specifically breaks down starches into simpler sugars, which are abundant in carbohydrate-rich foods like chips. Chips, made primarily from potatoes, contain starch that amylase can effectively digest. In contrast, chicken is primarily composed of proteins and fats, which do not contain starch, so salivary amylase has no effect on it. Therefore, while chips will undergo some digestion in the mouth, chicken will not be affected by this enzyme.
Where do you start to digest food?
You start digestion in your stomack
What do enzymes do in the human body?
Enzyme: [n.] Any of numerous proteins or conjugated proteins produced by living organisms and functioning as biochemical catalysts.Enzymes allow chemical reactions to occur at normal body temperature by lowering the activation energy needed to start a reaction.
Why conditions in the stomach are acidic?
The stomach is acidic because the stomach lining produces gastric acid. This helps the body start to digest proteins as well as provides a protective barrier against most bacteria and viruses.
What synthesis of one protein cannot take place without the presence of another protein is this statement true or false and why?
True. Some proteins require the presence of another protein to properly fold, assemble, or function. Examples include chaperone proteins that assist in the folding of other proteins or protein complexes that require multiple subunits to function correctly.
How do you prepare enzyme?
To prepare an enzyme, you must start with material with a high concentration of the enzyme, and then purify it many times. Be sure to avoid excessive heat.
