• Enzymes

​Review on : Enzymes
Enzymes → Protein Catalyzes (speed up) chemical reaction.

- Must bind to complementary substrate.
- Lower activation energy
- Reaction stops if something goes wrong

Multiple Choice

Which statement best describes the function of enzymes?

• Enzymes increase the activation energy of a reaction.

• Enzymes are consumed during a chemical reaction.

• Enzymes act as catalysts to speed up reactions without being used up.

• Enzymes lower the temperature of chemical reactions.

Multiple Choice

What happens to an enzyme when exposed to high temperatures?

• It becomes more active.

• Its structure may denature and lose function.

• It begins producing more substrate.

• It undergoes a permanent shape change that increases its activity.

Multiple Choice

Which of the following is TRUE about enzyme specificity?

• Enzymes can catalyze any reaction regardless of the substrate.

• Each enzyme is specific to one type of substrate.

• Enzymes only work with substrates at high concentrations.

• All enzymes can catalyze multiple types of reactions.
