Study Notes
Enzymes
- Enzymes are protein catalysts that increase the velocity of a chemical reaction without being consumed during the reaction.
Functions of Enzymes
- Enzymes help in signal transduction by catalyzing the phosphorylation of proteins, often involving protein kinase.
- They break down large molecules into smaller substances that can be easily absorbed by the body.
- Enzymes generate energy in the body, with ATP synthase being the enzyme involved in the synthesis of energy.
- They are responsible for the movement of ions across the plasma membrane.
- Enzymes perform various biochemical reactions, including oxidation, reduction, and hydrolysis, to eliminate non-nutritive substances from the body.
- They reorganize the internal structure of the cell to regulate cellular activities.
