Why are enzymes needed?

Answer 1

Because usually enzymes can help catalyze more than one substrate although they are specific. Enzymes are reusable (within reason) but do eventually wear out. Enzymes are efficient and don't need to be large to carry out their aid in the rate of chemical reaction processes.

Answer 2

Enzymes are only required in small amounts because enzymes are catalysts and are re-used so we don't need many of them.

The body can create its own digestive enzymes, however, the number it can create is limited (the enzyme potential). All foods contain their own digestive enzymes, however cooking can destroy them, thus depleting the body of its own potential and therefore causing premature aging. So to say "required" is to suggest that living for a long time is not a consideration.

Answer 3

Because enzymes are not consumed as a result of the reaction they catalyze. So a small amount of enzymes can be reused to catalyze a large number of reactions.

Answer 4

Enzymes are catalysts that speed up chemical reactions. Some common enzymes found in the body are amylase, lipase, protease, maltase and lactase. These are found in the digestive tract.

Answer 5

Enzymes are needed because they help break down foods.

Answer 6

They are used in small quantities because they are reusable and therefore there is no reason to have an excessive amount.

Answer 7

Only a small amount of enzymes is necessary since most enzyme catalyzed reactions have a plateau effect when dealing with larger than necessary amounts.

Answer 8

i dont know? good luck finding the answer :D XD
