What is the role of an enzyme in a chemical reaction?

Back

An enzyme acts as a catalyst, speeding up the chemical reaction without being consumed in the process.

Front

What do enzymes typically end with?

Back

Enzymes typically end with the suffix -ase.

Front

Why is photosynthesis important for plants?

Back

Photosynthesis is the process by which plants make their own food, using sunlight, carbon dioxide, and water.

Front

What is a substrate in the context of enzyme activity?

Back

A substrate is the reactant molecule upon which an enzyme acts.

Front

What does the structure of an enzyme determine?

Back

The structure of an enzyme determines its function and how well it can catalyze a reaction.

Front

What is ATP and why is it important?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, providing energy for various cellular processes.

Front

What is the active site of an enzyme?

Back

The active site is the specific region of an enzyme where the substrate binds and the reaction occurs.

Front

What factors can affect enzyme activity?

Back

Factors include temperature, pH, substrate concentration, and the presence of inhibitors or activators.

Front

What is the difference between a reactant and a product in a chemical reaction?

Back

Reactants are the starting materials in a chemical reaction, while products are the substances formed as a result of the reaction.

Front

How do enzymes lower the activation energy of a reaction?

Back

Enzymes lower the activation energy by stabilizing the transition state and providing an alternative reaction pathway.
