<span>The production of red blood cells, which transport oxygen, is triggered by a low level of oxygen in the blood. is correct.</span>
When glucose is high, cAMP is low; CAP does not bind the lac operator, and RNA polymerase does not bind the lac promoter. CAP is only active when glucose levels are low, which means the cAMP levels are high, and therefore the lac operon can only be transcribed at high rate when glucose is absent. The importance of this is that the bacteria only turns on the lac operon and start using lactose only after they have used up all the preferred energy source which is glucose.
Answer:
The correct answer is ATP and NADPH
Explanation:
During the light reaction, the light energy is absorbed by the chlorophyll pigment present in the thylakoid membrane which moves through different electron acceptors and allows the formation of NADPH and ATP.
This ATP and NADPH get utilized into the Calvin cycle during carbon fixation, reduction and regeneration steps. This utilization converts ATP and NADPH into ADP and NADP+. The energy released by them is used to fix carbon to produce organic compounds. Therefore the correct answer is ATP and NADPH.
