AP Biology - Energy & Enzymes

Front

What does 'C' represent in the context of energy and enzymes?

Back

Free energy released.

Front

What does it mean when an enzyme solution is said to be 'saturated'?

Back

The enzyme is working at its maximum speed.

Front

Describe the induced fit model of enzyme action.

Back

Enzymes mold with their substrates for a good fit.

Front

What is the optimum temperature for enzyme activity based on typical graphs?

Back

30°C.

Front

What term best describes a reaction that requires energy input?

Back

Endergonic.

Front

What is the role of enzymes in biochemical reactions?

Back

Enzymes act as catalysts to speed up reactions by lowering the activation energy.

Front

Define activation energy in the context of enzyme-catalyzed reactions.

Back

Activation energy is the minimum energy required for a reaction to occur.

Front

What is the difference between exergonic and endergonic reactions?

Back

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

Front

How does temperature affect enzyme activity?

Back

Enzyme activity typically increases with temperature up to an optimum point, after which it decreases.

Front

What is enzyme specificity?

Back

Enzyme specificity refers to the ability of an enzyme to select and catalyze a specific substrate.
