3.4 Cellular Energy

Front

What is the primary function of ATP in cellular processes?

Back

ATP serves as the main energy currency of the cell, providing energy for various biochemical reactions.

Front

What is the process called that converts light energy into chemical energy in plants?

Back

Photosynthesis.

Front

What are the two main types of metabolic reactions?

Back

Catabolic and anabolic reactions.

Front

What is the difference between catabolic and anabolic reactions?

Back

Catabolic reactions break down molecules to release energy, while anabolic reactions build molecules and require energy.

Front

What is metabolism?

Back

Metabolism refers to all the chemical reactions that occur within an organism.

Front

What happens to ATP when it loses a phosphate group?

Back

It is converted to ADP (adenosine diphosphate) and releases energy.

Front

What is phosphorylation?

Back

Phosphorylation is the addition of a phosphate group to a molecule, often activating or deactivating proteins.

Front

Which bond in ATP is broken to release energy?

Back

The bond between the second and third phosphate groups.

Front

What type of reaction is photosynthesis classified as?

Back

An anabolic reaction.

Front

What is the role of protein kinases in cellular signaling?

Back

Protein kinases phosphorylate specific proteins, thereby regulating their activity.
