The optimal growth temperature of a bacterium is most closely related to the optimal temperature for
A) transcription of DNA.
B) DNA replication.
C) enzyme function.
D) mRNA attachment to ribosomes.

Question

Quizplus · Accepted Answer

The optimal growth temperature of a bacterium is related to the optimal temperature for enzyme function because enzymes are the biological catalysts that drive all metabolic processes in cells, including growth and division. Enzyme activity is highly temperature-dependent, with each enzyme having an optimal temperature range at which it functions best. If the temperature is too far from the optimal range, the enzyme activity decreases, leading to a decrease in cell growth and division. Therefore, the optimal growth temperature of a bacterium is most closely related to the optimal temperature for enzyme function.
