Yeast cells that have defective mitochondria incapable of respiration will be able to grow by catabolizing which of the following carbon sources for energy? a) glucose b) proteins c) fatty acids d) glucose, proteins, and fatty acids e) such yeast cells will not be capable of catabolizing any food molecules, and will therefore die.

A. Glucose

Explanation:

When oxygen is not present to serve as a terminal electron acceptor to perform aerobic respiration for energy production, yeast cells carry out ethanol fermentation. Ethanol fermentation is an incomplete oxidation of glucose in the absence of oxygen. It obtains ethanol, CO2 and a small amount of energy to the yeast cell. Glucose is broken down into pyruvate by glycolysis. Decarboxylation of pyruvate forms acetaldehyde which in turn is reduced into ethanol accompanied by regeneration of NADH.

i believe the answer would be b. hope it : )

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
