Question

multiple choice question

changes in environmental conditions can cause the denaturation of cellular enzymes, resulting in:

• cell death.
• blocks to metabolic reactions.
• blocks to metabolic reactions and ultimately cell death.

Explanation:

Analyze the consequences of enzyme denaturation

Denaturation alters the three-dimensional shape of cellular enzymes, rendering them nonfunctional. Because enzymes catalyze essential biochemical pathways, their inactivation blocks metabolic reactions.

Determine the ultimate cellular outcome

Without active metabolic pathways to generate energy and synthesize cellular components, the cell cannot maintain homeostasis, which ultimately leads to cell death.

Answer:

• cell death.
• blocks to metabolic reactions.
• blocks to metabolic reactions and ultimately cell death. (Correct answer)
