Digestive Enzymes?

Digestive Enzymes?Which of the following is true about digestive enzymes?
One enzyme can speed many types of chemical processes

Enzymes are not sensitive to temperature

Enzymes that work in the acidic environment of the stomahc cannot work in the basic or alkaline environment of the small intestine and vice versa

Enzymes typically work independently of vitamins and minerals

I'm going to say:

Enzymes that work in the acidic environment of the stomach cannot work in the basic or alkaline environment of the small intestine and vice versa.

Not true. Enzymes are very specific.

Enzymes are not sensitive to temperature.

Not true. Enzymes are proteins. They denature (lose 3 dimensional structure) at high temperatures.

Enzymes typically work independently of vitamins and minerals
Not true. Enzymes often require minerals or vitamins.


This is the true one:

Enzymes that work in the acidic environment of the stomahc cannot work in the basic or alkaline environment of the small intestine and vice versa.

This is why the digestive enzymes from your stomach don't digest your intestine. Enzymes are often pH sensitive.

Q1: False, enzymes are specific, they only react on specific substrates.

Q2: False, enzymes are proteins, they are easily denatured at high temperature, usually, 40C.

Q3: True, enzymes are built up of amino acid, which has both amino and carboxyl group. These are groups which easily affected by pH of the environment.

Q4: False. Sometimes, enzymes required vitamins, minerals or other trace elements to speed up an enzymatic reaction.
