A drug reduces mitochondrial activity in nephrons of the kidney. Which chemical will be present in increased amounts in the urine?
Correct answer: B. Glucose
- A. Ammonia
- B. Glucose
- C. Hydrogen bicarbonate
- D. Urea
Explanation
This happens because in mitochondria aerobic respiration occurs(breakdown of food in presence of oxygen)The food is glucose.Aerobic respiration:Glucose+O2=CO2 + ATPSo if the mitochondrial activity is reduced then glucose will not be used and will be excreted out through urine.

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
