Which of the following statements about enzymes in organic chemistry reactions is false?
A
Enzymes increase the rate of a reaction by lowering the activation energy.
B
Enzymes can be affected by changes in temperature and pH.
C
Enzymes are consumed in the reaction they catalyze.
D
Enzymes are highly specific to the substrates they bind.
Verified step by step guidance1
Understand the role of enzymes: Enzymes are biological catalysts that speed up chemical reactions without being consumed in the process. This means they can be used repeatedly in multiple reaction cycles.
Analyze the statement about activation energy: Enzymes increase the rate of a reaction by lowering the activation energy, which is the energy barrier that must be overcome for a reaction to proceed. This statement is true.
Consider the effect of temperature and pH: Enzymes are sensitive to environmental conditions such as temperature and pH. Extreme changes can denature the enzyme, altering its structure and function. This statement is true.
Evaluate the specificity of enzymes: Enzymes are highly specific to the substrates they bind due to their unique active sites, which fit only specific substrate molecules. This statement is true.
Identify the false statement: The statement 'Enzymes are consumed in the reaction they catalyze' is false because enzymes are not consumed; they remain unchanged after the reaction and can catalyze subsequent reactions.
