AP/SUPA - Chapter 8: Metabolism, Energy and Enzymes

Front

What do enzymes typically end with?

Back

-ase

Front

What is it called when a molecule binds to an enzyme at a site different from the active site and decreases the ability of the active site to bind to the substrate?

Back

Allosteric Inhibition

Front

What are Zinc and Iron classified as in relation to enzymes?

Back

Cofactors

Front

What role does cyanide play when it stops the mitochondria from producing ATP?

Back

Inhibitor

Front

A chemical reaction with a positive ΔG is best described as what?

Back

Endergonic

Front

What is the term for a substance that increases the rate of a chemical reaction without being consumed?

Back

Catalyst

Front

What is the primary function of enzymes in biological systems?

Back

To accelerate chemical reactions by lowering activation energy.

Front

What is the difference between competitive and non-competitive inhibition?

Back

Competitive inhibition occurs when an inhibitor competes with the substrate for the active site, while non-competitive inhibition occurs when an inhibitor binds to an allosteric site, changing the enzyme's shape.

Front

What is the role of coenzymes in enzyme activity?

Back

Coenzymes are organic molecules that assist enzymes in catalyzing reactions.

Front

What is the significance of the active site of an enzyme?

Back

The active site is the region where substrate molecules bind and undergo a chemical reaction.
