i. In bright sunlight, the Calvin cycle takes place in the stroma. At the time of the Calvin cycle, the products of the light-dependent reactants, that is, ATP and NADPH are used to transform molecules of carbon dioxide into high-energy sugars.
ii. In the darkness, the Calvin cycle also takes place in the stroma. During the Calvin cycle, the products of the light-dependent reactions, that is, ATP and NADPH are used to transform the molecules of carbon dioxide into high-energy sugars.
iii. If the plant has been kept in dark for an extended period of time, then there may be not enough production of ATP and NADPH taking place in order to continue the Calvin cycle.
Answer A
Explanation: It gives a lot of info about the food chain so it is A
Answer:
The second step in cellular respiration is called the Krebs cycle. The Krebs cycle uses pyruvic acid to create ATP, along with additional molecules like NADH, FADH2, and CO2. The NADH and FADH2 molecules are used during the final step of cellular respiration, while the CO2 is exhaled
