What is the primary role of enzymes in a cell?

  1. Create energy

  2. Transport proteins

  3. Increase the rate of a reaction

  4. Create new cell components

The correct answer is: Increase the rate of a reaction

Enzymes play a critical role in increasing the rate of biochemical reactions within a cell. This means that they help to speed up the chemical processes that are necessary for cellular functions to occur. Options A, B, and D are incorrect because enzymes are not directly involved in creating energy, transporting proteins, or creating new cell components. Enzymes function by binding to specific substrates and lowering the activation energy needed for a reaction to occur, but they do not participate in the reaction themselves. Therefore, option C is the most accurate choice to describe the primary role of enzymes in a cell.
