Enzymes - ESL

Front

What are enzymes composed of?

Back

Enzymes are composed of amino acids.

Front

What is the optimum pH of an enzyme if it is stated to be 6.6?

Back

The optimum pH of the enzyme is 6.6.

Front

What happens to an enzyme when it is denatured?

Back

When an enzyme is denatured, it loses its shape.

Front

True or False: Every enzyme has an optimal temperature and pH.

Back

True.

Front

What type of macromolecule are enzymes?

Back

Enzymes are proteins.

Front

What is the role of enzymes in biochemical reactions?

Back

Enzymes act as catalysts to speed up biochemical reactions by lowering the activation energy.

Front

What is activation energy?

Back

Activation energy is the minimum energy required for a chemical reaction to occur.

Front

How does temperature affect enzyme activity?

Back

Enzyme activity typically increases with temperature up to a certain point, after which it may decrease due to denaturation.

Front

What is the effect of pH on enzyme activity?

Back

Each enzyme has an optimal pH range where it functions best; outside this range, activity may decrease.

Front

What is a substrate in relation to enzymes?

Back

A substrate is the specific reactant that an enzyme acts upon.
