Question

Metabolic reactions are necessary for the body to function and maintain homeostasis. Which of the following statements describes an enzyme’s role in these reactions?

Enzymes are used up as a part of the reaction and cannot be used again.

Enzymes can be any shape to bind to the substrate.

Enzymes are formed into lipids.

Enzymes are catalysts that lower the activation energy allowing the reaction to occur.

Answer 1

Enzymes are proteins that help in metabolic reactions by assisting in the transfer of electrons from one molecule to another. Hence, during metabolic functions, enzymes serve as catalysts that lower the activation energy, allowing such reactions to occur. During metabolism, enzymes may act on molecules called as substrates and is converting them into a different molecule that is simply known as products.
