BIOMOLECULES AND ENZYMES

Detailed explanation-1: -A protein that speeds up chemical reactions in the body.

Detailed explanation-2: -Definition. An enzyme is a biological catalyst and is almost always a protein. It speeds up the rate of a specific chemical reaction in the cell.

Detailed explanation-3: -Temperature: Raising temperature generally speeds up a reaction, and lowering temperature slows down a reaction. However, extreme high temperatures can cause an enzyme to lose its shape (denature) and stop working. pH: Each enzyme has an optimum pH range. Changing the pH outside of this range will slow enzyme activity.

Detailed explanation-4: -Enzymes are mainly globular proteins-protein molecules where the tertiary structure has given the molecule a generally rounded, ball shape (although perhaps a very squashed ball in some cases).

Detailed explanation-5: -Answer and Explanation: Proteins can speed up chemical reactions using a few different tactics. The main premise behind these proteins, called enzymes, is known as the induced-fit model. A substrate, the starting material, binds to the enzyme’s active site.
