Front

What happens to the enzyme 'catalase' during the breakdown of hydrogen peroxide?

Back

The enzyme would remain unchanged in any way.

Front

What is the definition of Selective Permeability?

Back

The ability of the cell membrane to allow some things to pass through while preventing other things from passing through.

Front

How is the structure of enzymes related to their function?

Back

Enzymes’ unique active site allows it to fit with only one substrate molecule.

Front

What is true about active transport?

Back

It requires energy.

Front

Why is the 'lock and key' analogy used to describe enzyme function?

Back

Each enzyme will fit with only one specific kind of substrate.

Front

What is an enzyme?

Back

A protein that acts as a catalyst to speed up chemical reactions in the body.

Front

What is the role of the active site in an enzyme?

Back

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

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy, while active transport requires energy.

Front

What is a substrate in the context of enzyme activity?

Back

A substrate is the reactant molecule that an enzyme acts upon.

Front

What is the significance of enzyme specificity?

Back

Enzyme specificity ensures that enzymes only catalyze specific reactions, preventing unwanted reactions.
