Question

Why does Calvin cycle needs the products of light phase?
A. Because it is needed to convert oxygen into sugar.
B. Because it is needed to convert sugar into oxygen.
C. Because it is needed to convert carbon dioxide into sugar.
D. Because it is needed to convert sugar into carbon dioxide.​

Answer 1

Answer:

Although the Calvin Cycle is not directly dependent on light, it is indirectly dependent on light since the necessary energy carriers (ATP and NADPH) are products of light-dependent reactions. ... In the last stage of the Calvin Cycle, RuBP is regenerated, which enables the system to prepare for more CO2 to be fixed

Answer 2

Calvin cycle needs the products of light phase A. Because it is needed to convert oxygen into sugar.

Explanation:

Although the Calvin Cycle is not light-dependent directly, it is light-Dependent indirectly because the required energy carriers  are results of light-dependent processes.

Because it is needed to convert oxygen into sugar:

• Oxygen is released as a result. Oxygen is required to break down glucose in cellular respiration, producing chemical energy and heat in the process.

Because it is needed to convert sugar into oxygen:

• Autotrophs, or self-feeding plants, make their own nourishment. Photosynthesis converts water, sunshine, and carbon dioxide into oxygen and simple sugars, which are used as fuel by the plant.

Because it is needed to convert carbon dioxide into sugar:

• An enzyme is an organic catalyst utilised by plants; the researchers used tungsten diselenide, a metal compound.

Because it is needed to convert sugar into carbon dioxide:

• Ethanol fermentation, also known as alcoholic fermentation, is a biological process in which carbohydrates like glucose, fructose, and sucrose are converted into cellular energy.
