Yeast cells that have defective mitochondria incapable of respiration will be able to grow by catabolising which of the following carbon sources for energy?
A) glucose
B) cholesterol
C) fatty acids
D) amino acids

Question

Quizplus · Accepted Answer

Yeast cells with defective mitochondria cannot carry out oxidative phosphorylation to generate ATP from glucose. However, they can still use glucose as a source of carbon and energy through glycolysis, which does not require functional mitochondria. Therefore, of the options given, glucose is the only suitable carbon source for growth of these yeast cells. Cholesterol, fatty acids, and amino acids require functional mitochondria for metabolism and ATP production.
