Verified step by step guidance

Understand the role of a catalyst: In chemistry, a catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process.

Identify the biological catalysts: In the human body, enzymes act as catalysts. Enzymes are proteins that speed up biochemical reactions necessary for life.

Consider the options given: Lipids, Proteins, Vitamins, Carbohydrates.

Recognize that proteins, specifically enzymes, are responsible for catalyzing reactions in the body.

Conclude that proteins are the correct answer because they include enzymes, which are the biological catalysts in body processes.
