Enzymes are proteins that accelerate biochemical reactions, essential for nearly all cellular processes. They enable reactions to occur efficiently at body temperature, with each enzyme being highly specific to its reaction.

What is the primary function of enzymes in biochemical reactions?

• To provide energy for reactions

• To slow down reactions

• To change the products of reactions

• To speed up reactions

Why are enzymes crucial for reactions in living cells?

• They decrease the need for reactants

• They eliminate the need for energy

• They allow reactions to occur at body temperature

• They increase the temperature of reactions

How do enzymes affect the efficiency of cellular reactions?

• They make reactions slower

• They make reactions more efficient

• They stop reactions from occurring

• They change the reactants

What is true about the specificity of enzymes?

• Each enzyme can catalyze any reaction

• Enzymes are not specific to any reaction

• Each enzyme is specific to a particular reaction

• Enzymes can only catalyze reactions at high temperatures

How many different types of enzymes exist?

• Only a few

• Many, each specific to a reaction

• Only one type

• None, they are all the same
