Enzymes are crucial for speeding up biochemical reactions in living cells, allowing them to occur efficiently at body temperature. Each enzyme is highly specific to its particular reaction, ensuring precise biochemical processes.

What is the primary function of enzymes in biochemical reactions?

• To change the products of reactions

• To provide energy for reactions

• To slow down reactions

• To speed up reactions

How do enzymes affect the rate of biochemical reactions?

• They stop the reactions

• They increase the rate

• They have no effect on the rate

• They decrease the rate

Why are enzymes crucial for reactions at body temperature?

• They increase the temperature of the body

• They allow reactions to occur without additional heat

• They change the pH of the body

• They cool down the reactions

Which statement best describes the specificity of enzymes?

• Enzymes can catalyze any reaction

• Enzymes work only in acidic environments

• Each enzyme is specific to a particular reaction

• Enzymes are not specific and can work on multiple reactions

What is a unique feature of enzymes in biological systems?

• They work only at high temperatures

• They are not affected by environmental conditions

• They are highly specific to their reactions

• They are non-specific
