WebAn experiment was done to investigate the effects of low pH on enzymes activities. According to Dunaway, Mariano, D. (2008) enzymes are protein in nature. They are used to speed up the rate of reactions. At, the end of the experiment, enzyme is not used up. There are several factors that affect the rate of enzymatic activities. WebMar 5, 2024 · The main digestive enzyme in the stomach is pepsin, which works best at a pH of about 1.5. These enzymes would not work optimally at other pHs. These enzymes would not work optimally at other pHs. Trypsin is another enzyme in the digestive system, which breaks protein chains in food into smaller parts.

How does pH influence the rate of enzyme reactions?

WebDue to this fact, it is less likely for the enzyme to de-nature. However, for pH level 7.4 and 6.0, I think that the enzyme will not affect the rate of reaction as the acid and alkali levels are too high and also too low, which will cause the active site to denature, not allowing the lock and key theory to take place. Apparatus: 1 ... WebA typical enzyme molecule can convert 1,000 substrate molecules per second. The rate of an enzymatic reaction increases with increased substrate concentration, reaching maximum velocity when all active sites of the enzyme molecules are engaged. The enzyme is then said to be saturated, the rate of the reaction being determined by the speed at ...
