Answer: Option A.
To catalyze chemical reactions
Explanation:
Enzymes are substances or biological catalysts that speed up and drive chemical reactions in the cells.
Without enzymes life will not exist because enzymes are present in most cells and help to perform complex tasks the cells cannot do on their own.
Enzymes perform functions in digestive system by breaking complex food in to simpler form which the body can absorb.
Enzymes help also in metabolism. Enzymes catalyse chemical reactions.
Answer:
a. catalyze chemical reactions. Explanation:
Emzymes are protein that catalyze chemical reactions. Biochemical activities in the body is increased by enzymes.
Enzymes operate without affecting equilibrium while some catalyzes reaction without affecting themselves. Enzymes have active site where substrate binds to for reaction to take place.
Some factors such as temperature,pH affects enzyme reaction. At body temperature of 37°C enzymes in human are active at a low temperature they are slow in action. They pH at which enzymes function depends on the reaction to catalyze. Amino acids are building blocks of protein and protein are enzymes.
