Front

What is metabolism?

Back

The sum of all chemical reactions that occur within a living organism.

Front

What is the final electron acceptor in cellular respiration?

Back

Oxygen.

Front

What is the function of NADP+?

Back

It is an electron carrier.

Front

How does a decrease in temperature affect enzyme activity?

Back

It can decrease the rate of reaction by causing a change in the shape of the protein.

Front

What is competitive inhibition?

Back

A type of enzyme inhibition where the inhibitor competes with the substrate for the active site.

Front

What is cellular respiration?

Back

The process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.

Front

What is photosynthesis?

Back

The process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

What role does ATP play in cellular processes?

Back

ATP serves as the primary energy currency of the cell.

Front

What is the role of enzymes in biochemical reactions?

Back

Enzymes act as catalysts to speed up chemical reactions without being consumed.

Front

What is the difference between competitive and noncompetitive inhibition?

Back

Competitive inhibition involves the inhibitor competing with the substrate for the active site, while noncompetitive inhibition occurs when the inhibitor binds to a different site, reducing enzyme activity.
