Answer:
Explanation:
Active cellular transport:
- It is the movement of molecules against the concentration gradient (from low concentration to high).
- Active transport requires expense of energy supplied by ATP.
- It is a rapid way to transport of large sized molecules.
Passive cellular transport:
- It is the movement of molecules along the concentration gradient (from high concentration to low).
- Passive transport does not require expense of energy.
- It is a slow process and small sized molecules get transprorted.
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.
