Question

a researcher hypothesizes that cells with this gene mutation will have impaired energy metabolism. which statement provides the strongest evidence? (1 point) heat stress increases both mrna and protein production. low nutrients cause similar changes to enzyme activity as gene mutation. normal conditions maintain 100% transcription and translation. protein levels and enzyme activity are dramatically reduced, limiting key metabolic reactions.

Explanation:

The hypothesis is about impaired energy metabolism in cells with gene - mutation. Protein levels and enzyme activity being dramatically reduced and limiting key metabolic reactions directly relate to energy metabolism impairment. Heat stress increasing mRNA and protein production, low nutrients causing similar enzyme changes as gene - mutation, and normal conditions maintaining 100% transcription and translation do not directly address the impaired energy metabolism due to gene - mutation as strongly.

Answer:

Protein levels and enzyme activity are dramatically reduced, limiting key metabolic reactions.
