Front

What is metabolism?

Back

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

Front

Which process does NOT produce glucose?

Back

Light reactions in photosynthesis.

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 noncompetitive inhibition?

Back

A type of enzyme inhibition where the inhibitor binds to an enzyme at a site other than the active site, reducing the enzyme's activity.

Front

What is the active site of an enzyme?

Back

The location where the enzyme and substrate bind.

Front

Define chemosynthesis.

Back

The process by which certain organisms convert carbon compounds into organic matter using energy derived from chemical reactions.

Front

What is cellular respiration?

Back

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

Front

What are the products of the light reactions in photosynthesis?

Back

Oxygen, NADPH, and ATP.

Front

What is the role of enzymes in biological reactions?

Back

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

Front

What is competitive inhibition?

Back

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