Explanation:

1. The subunits of DNA are nucleotides which store genetic information.
2. Organic compounds like $C_{6}H_{12}O_{6}$ (glucose) are common in living organisms.
3. Carbohydrates are the quickest source of energy for the body.
4. Glycolysis is the first - step in cellular respiration that releases energy from glucose.
5. The main energy source produced by cellular respiration is ATP. When oxygen is not present, glycolysis is followed by fermentation.
6. Cellular respiration requiring oxygen is aerobic.
7. The correct sequence in cellular respiration is Glycolysis → Krebs cycle → Electron transport chain.

Answer:

1. a. nucleotides that store information
2. a. $C_{6}H_{12}O_{6}$
3. a. carbohydrates
4. c. Glycolysis
5. c. fermentation
6. a. aerobic
7. d. Glycolysis → Krebs cycle → Electron transport chain
