What is the primary purpose of an enzyme in a biochemical reaction?
To increase the activation energy required
To act as a reactant
To lower the activation energy required
To change the equilibrium of the reaction
Which of the following best describes substrate specificity of enzymes?
Enzymes can act on any substrate without restriction.
Enzymes only interact with substrates of similar size.
Enzymes catalyze reactions by fitting precisely with specific substrates.
Enzymes degrade substrates indiscriminately.
What role do cofactors play in enzymatic reactions?
They are waste products of the enzyme activity.
They provide additional chemical groups to enhance reactions.
They completely replace enzymes in the reaction.
They disable the enzyme and halt the reaction.
