AP Bio Unit 3: Enzymes

Front

What are enzymes composed of?

Back

Enzymes are composed of amino acids.

Front

What is the optimal temperature for enzyme activity based on the graph?

Back

The optimal temperature for this enzyme is 30°C.

Front

What is a catalyst?

Back

A catalyst is a substance that speeds up the rate of a chemical reaction.

Front

What type of reaction is shown if energy is absorbed?

Back

Endothermic reaction.

Front

Is photosynthesis an endothermic or exothermic reaction?

Back

Photosynthesis is an endothermic reaction.

Front

What is the role of enzymes in biological reactions?

Back

Enzymes act as catalysts to speed up biological reactions.

Front

What factors can affect enzyme activity?

Back

Temperature, pH, and substrate concentration can affect enzyme activity.

Front

What is the active site of an enzyme?

Back

The active site is the region on the enzyme where substrate molecules bind.

Front

What happens to enzymes at high temperatures?

Back

Enzymes can denature and lose their functionality at high temperatures.

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 a different part of the enzyme.
