- 10. Multiple Choice
Which of the following statements describes the role of ATP in animal cells?
ATP stores and releases energy.
ATP forms the channels in the plasma membrane.
ATP serves as the hereditary material in the nucleus.

- 11. Multiple Choice
Which statement is supported by the diagram?
The mitochondrion uses the sun’s energy directly.
The end products of photosynthesis do not provide energy for cellular respiration.
The main source of energy for photosynthesis is carbohydrates.
Carbohydrates are converted into ATP by the mitochondrion.
- 12. Multiple Choice
The diagram below represents some chemical events that take place in one type of autotrophic nutrition. The arrows labeled A best represent...
carbon dioxide
glucose
energy
lactic acid
- 13. Multiple Choice
Which of the following is the correct equation for photosynthesis?
CO2 + H2O + light → C6H12O6 + O2
6CO2 + 6H2O + light → C6H12O6 + 6O2
C6H12O6 + 6O2 → 6CO2 + 6H2O + energy
C6H12O6 + O2 → CO2 + H2O + energy
