What is the function of enzymes in biological systems? f Enzymes act as substrates when the
necessary proteins are unavailable.
g Enzymes bond with substrates to
create the new reaction products.
h Enzymes act as catalysts to drive
chemical reactions forward.
j Enzymes act as products to create
new chemical reactions.

Explanation:

Enzymes are catalysts.

They lower the activation energy required to carry out a reaction, which speeds up the reaction. They attach to a molecule known as a substrate at the active site in a specific way.

Enzymes are incredibly important for life. Many reactions wouldn't occur at a rate that can support life, but enzymes allows this to happen. They assist in digesting food, replication genetic material, and more.

So, we know that enzymes are catalysts that make reactions efficient. Therefore, choice H is the best answer.

Enzymes help speed up chemical reactions in the human body. They bind to molecules and alter them in specific ways. They are essential for respiration, digesting food, muscle and nerve function, among thousands of other roles.
