Answer:

C. CALVIN CYCLE(LIGHT INDEPENDENT REACTIONS OF PHOTOSYNTHESIS.

Explanation:

Photosynthesis is the process whereby green plants manufacture their food (organic matters in form of glucose) from carbon IV oxide and water molecules in the presence of sunlight.

The glucose formed undergoes two purposes; provision of energy and in the fixing of carbon.

This process involved two steps : The light dependent process and the light independent (Calvin cycle).

The light dependent reaction takes place in the thylakoid membrane and requires supply of light energy.

ATP and NADPH are formed, water molecules are also formed.

The light independent reaction occurs in the stoma and does not require light energy. The process used the ATP and NADPH formed from the light dependent reaction to fix carbon and produce three carbon sugars.

So the Calvin cycle light independent reaction is involved in the fixing of carbon molecules into organic molecules in the absence of sunlight and the ATP and NADPH formed from the light dependent process of photosynthesis.

How does light intensity affect oxygen production?
ZanzabumX [31]
Greater light intensity would mean a faster rate of photosynthesis in plants. photosynthesis takes in carbon dioxide and water to produce glucose and oxygen. therefore, a greater light intensity would mean faster oxygen production

What structure on the human body is comparable to the alula?
melomori [17]
The alula is a small structure that is found on birds. It is located at the joint between the hand wing and the arm wings of birds and it is the freely moving, first digit of a bird's wing. It is normally used by birds in slow flight. In humans, the structure that is comparable to the alula is the thumb.
