These are secreted by the stomach:
- pepsiogen precursor for pepsin (an enzyme)
- intrinsic factor (so that B12 can be absorbed)
- gastrin (a hormone)
- ghrelin (a hormone)
Only pepsin fits your question as pepsiogen needs HCl to convert into pepsin.
Pepsin.

∙ 9y agoPepsin is an enzyme that breaks down proteins. It is actually secreted as pepsinogen by the chief cells of the gastric glands in the stomach. Gastric lipase breaks down certain lipids, but is not extremely active. Both of these are active at a very low pH which is found in the stomach.

What is a gastric protease?
It is an enzyme that is produced in the stomach and used to digest proteins to polypeptides. It works best in acidic conditions
The pH at which an enzyme works best can vary greatly from one enzyme to the other?
true
What is the effect of pH upon the relative enzyme activity?
Different enzymes work best at different pH. This is refered to as the ideal pH for the enzyme. For example, the digestive enzyme trypsin works best at an acidic pH while alkaline phosphatase works best at a basic pH. Therefore, enzyme activity varies with pH and this variation depends on the enzyme being studied
Pepsin a digestive enzyme found in the stomach works best at a pH near?
Pepsin works best in acidic environments and it's optimal pH (the pH at which it works best) is 2.0
Why does pepsin work best at 37 degrees C?
Pepsin works best at 37 C because that is it's optimal temperature. The temperature at which it works best. Every enzyme has one which is based on the molecular geometry and binding of the protein...
Does amylase work in acid or alkali?
works best in neutral conditions
Which enzyme works best in alkaline conditions?
Pepsin in the stomach
What is a gastric protease?
It is an enzyme that is produced in the stomach and used to digest proteins to polypeptides. It works best in acidic conditions
What is the material in which an enzyme acts?
What refers to the set of conditions including oh temperature and or light under which a certain type of protein cell works best
The pH at which an enzyme works best can vary greatly from one enzyme to the other?
true
What enzyme works best in alkaline?
37.5 centigrade.
What is the true relationship between pH and enzyme action?
The enzyme has an optimal point of pH at which the enzyme works best. For example a catalase enzyme works best in a pH of 7. When the pH changes it denatures the enzyme causing it to not be able to react with the substrate.
What is the effect of pH upon the relative enzyme activity?
Different enzymes work best at different pH. This is refered to as the ideal pH for the enzyme. For example, the digestive enzyme trypsin works best at an acidic pH while alkaline phosphatase works best at a basic pH. Therefore, enzyme activity varies with pH and this variation depends on the enzyme being studied
Where does chemical digestion of fat occur?
The small intestines, where it is then broken down into glycerol and fatty acids.
All enzymes act best at a pH close neutral?
This is not true. Different enzymes thrive in completely different pH conditions. Consider the protease pepsin, which works in the stomach. It breaks down proteins in acidities as low as pH 2. In the duodenum, lipase works best in slightly alkaline conditions.
What is the optimum temperature for enzyme 2?
55 CThis enzyme works best at a temperature of 50 C and a pH of 12.If the enzyme will be above this temperature, it will denature.
Do all enzymes work best at neutral pH?
No, the optimum pH for an enzyme depends on the environment in which it normally works. Your stomach is an acidic environment which contains an enzyme called pepsin. This not only works better in acid environments but actually denatures (that is, totally stops working) if the pH rises above 5.0.
