0. During Calvin cycle, it takes 3 turns to produce 6 molecules of glyceraldehyde-3-phosphate where 5 molecules proceeds for the regeneration of RuBP and 1 molecule is use for the synthesis of what molecule?

A. RuBP C. 2,3—PGA

B. Oxygen D. Glucose

11. The best explanation of the equation in an aerobic respiration.

A. Glucose is oxidized to produce the energy

B. Oxygen oxidizes glucose to produce CO2, H2O and Energy

C. Glucose plus the presence of oxygen produces the energy needed by the organism

D. The oxidation of glucose produces energy as the product and molecules of CO2 and H2O as a by-product

12. What is the importance of anaerobic respiration?

A. produces lactic acid needed by the organism

B. provides the right energy needed by the organism

C. the failed—play safe of organisms when aerobic respiration takes all the oxygen supply to be used during

strenuous activities

D. all of the above

13. The obvious difference of aerobic and anaerobic respiration is the presence of oxygen in the process and the

products they produce. This means that

A. NADH for aerobic and NADPH for anaerobic respiration

B. ATP is produced during aerobic respiration and ADP for anaerobic respiration

C. ATP is the product of aerobic respiration and NADH is the product of anaerobic respiration

D. ATP is the product of aerobic respiration and Lactic acid for anaerobic respiration to be utilize by the organism​
