Front

What is the structure of enzymes that specifically interacts with substrate molecules?

Back

Active site.

Front

What is the primary role of enzymes in biological reactions?

Back

Lower the activation energy.

Front

What happens to water during photolysis when struck by a photon of light?

Back

It is broken into O₂, H⁺ ions, and electrons.

Front

Define enzymes.

Back

Biological catalysts that speed up chemical reactions by lowering the activation energy.

Front

What is activation energy?

Back

The minimum energy required for a chemical reaction to occur.

Front

What is the role of ATP in cellular processes?

Back

ATP serves as the primary energy currency of the cell.

Front

What is photolysis?

Back

The process of using light energy to break down molecules, such as water in photosynthesis.

Front

What is NADPH?

Back

A reduced form of NADP+ that acts as an electron carrier in photosynthesis.
