3.4 Cellular Energy

Front

What is the primary process through which ATP is produced in cells?

Back

Cellular respiration.

Front

What type of reaction is an endergonic reaction also known as?

Back

An anabolic reaction.

Front

What is the characteristic of an endergonic reaction in terms of Gibbs free energy?

Back

Positive ΔG.

Front

What term describes all the chemical reactions that occur within an organism?

Back

Metabolism.

Front

What is the result of the hydrolysis of ATP?

Back

ADP (adenosine diphosphate) and inorganic phosphate.

Front

What is the role of ATP in cellular processes?

Back

ATP serves as the primary energy currency of the cell.

Front

What is the difference between exergonic and endergonic reactions?

Back

Exergonic reactions release energy, while endergonic reactions require energy input.

Front

What is the significance of ΔG in biochemical reactions?

Back

ΔG indicates the spontaneity of a reaction; negative ΔG means the reaction is spontaneous.

Front

What are the two main types of metabolic pathways?

Back

Catabolic pathways (break down molecules) and anabolic pathways (build up molecules).

Front

How does ATP provide energy for cellular work?

Back

ATP releases energy when its phosphate bonds are broken.
