How do enzymes speed up chemical reactions? enzymes
a.lower the activation energy of chemical reactions.
b.raise the temperature of the cell, speeding chemical reactions.
c.store atp, allowing more energy to be used in chemical reactions.
d.act as miniature 'transfer trucks', gathering materials for chemical reactions, and placing them together.

enzymes are biological catalysts which speed up the speed of reaction by lowering the activation energy without itself being consumed for e.g to digest proteins there are dfrn enzymes and to digest carbohydrates there are dfrn enzymes every enzyme is specific in its function

Answer:

The correct option is a. Enzymes lower the activation energy of chemical reactions.

Explanation:

Enzymes are molecules, usually proteins, that act as catalysts, that is, they accelerate the chemical reactions that occur in the cells of living organisms, they act on molecules called substrates and each one is linked to a region of the enzyme, called active site, which is the site where catalytic fuction occurs. The catalytic function is to reduce the activation energy necessary to start biochemical reactions, that is to reduce the energy needed to break and create new bonds, allowing the formation of a product to be much faster.
