The energy required to run the Calvin cycle reactions of photosynthesis comes from which two substances produced during the ligh
Lelu [443]

Answer:

a. ATP and NADPH

Explanation:

Light-dependent reactions of photosynthesis include splitting of water in the presence of sunlight and release of electrons. The electrons move from the reaction center of the PS-II via electron carriers to the PS-I. From the reaction center of PS-I, the electrons finally reach NADP reductase and reduce NADP into NADPH.

During this electron transfer via electron carriers, a proton concentration gradient is generated across the thylakoid membrane. The energy of this gradient is used to drive ATP synthesis. ATP and NADPH formed during the light-dependent phase of photosynthesis are then used during the reactions of the Calvin cycle.

Why is lactic acid moved from the muscles to the liver
Sati [7]

Explanation:

Significance. The cycle's importance is based on the prevention of lactic acidosis in the muscle under anaerobic conditions. However, normally, before this happens, the lactic acid is moved out of the muscles and into the liver. The cycle is also important in producing ATP, an energy source, during muscle activity.
