Photorespiration is detrimental for a plant because Homework a. 02 is required b. CO2 is synthesized c. RuBP is degraded d. glucose is synthesized e. no glucose is produced 15. Where does the C4 cycle get its name? a. Only four carbons are used in the cycle. b. It is a four-step process. c. Four CO2 molecules are released d. The first product in the cycle has four carbons. e. PEP is a four-carbon molecule. 16. If C4 photosynthesis prevents photorespiration, why haven't all plants evolved to use the C4 pathway? a. b. c. All plants will evolve to be C4 in time C4 produces some toxic by-products C4 is not advantageous in all climates 17. What is the significance of the C4 pathway? It gives individual plants the option of undergoing the Cs or C4 pathway for more efficient photosynthesis. It minimizes photorespiration in plants that live in dry environments It maximizes photorespiration in plants that live in dry environments It minimizes photorespiration in plants that live in humid environments a. b. c. d.Explanation / Answer
Answer:
14). E. No glucose is produced
Explanation:
Photorespiration is detrimental fo a plant because as it diverts energy from the calvin cycle by making useless products.
15). D. The first product in the cycle has four carbons
Explanation: The first product produced in the C4 cycle is oxaloacetate, which contains four carbons so the cycle is called c4 cycle.
16). C. C4 is nto advantageous in all climates
Explanation:
C4 photosynthesis is clearly advantageous in hot and dry climates, this is not true in cool and moist ones. This is because C4 photosynthesis is more complex: it has more steps and requires a specialized anatomy.
17). C. It minimizes photorespiration in plants that live in dry environments
