maria [59]

Answer:

Digestive enzymes play a key role in breaking down the food you eat. These proteins speed up chemical reactions that turn nutrients into substances that your digestive tract can absorb. Your saliva has digestive enzymes in it. Some of your organs, including your pancreas, gallbladder, and liver, also release them.

For most enzymes to operate in the body, the optimal temperature is 37 degree Celsius or 98 degrees Fahrenheit. Most of the human enzymes have a maximal activity at pH around 7.2, which is the pH of most body fluids. However, there are exceptions such as, pepsin.
