Front

What is the primary function of carbohydrates in living organisms?

Back

To store energy and provide structural support.

Front

Which macromolecule is primarily responsible for storing energy in the body?

Back

Lipid.

Front

What happens to an enzyme when it is denatured?

Back

It loses its shape and functionality.

Front

What is the active site of an enzyme?

Back

The region on the enzyme where the substrate binds.

Front

What effect does high temperature have on enzymes?

Back

Enzymes can denature (change shape) and lose their function.

Front

What is the optimal temperature range for most enzymes?

Back

Typically around 37°C (98.6°F), but varies by enzyme.

Front

What is the role of enzymes in biochemical reactions?

Back

To lower the activation energy required for the reaction.

Front

What is a substrate in the context of enzyme activity?

Back

The reactant molecule that an enzyme acts upon.

Front

What is the relationship between enzyme concentration and reaction rate?

Back

Increasing enzyme concentration generally increases the reaction rate until saturation.

Front

What is enzyme saturation?

Back

The point at which all active sites of the enzyme are occupied by substrates.
