(A) Glysolysis (B) Krebs cycle (citric acid cycle) (C) Calvin cycle (light-independent reactions of photosynthesis) (D) Light-dependent reactions of photosynthesis (E) Chemiosmosis Process in which carbon from CO2 is incorporated into organic molecules A

Answer 1

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.

Answer 2

Answer:

The correct heading to which the given phrase is closely related is

C. Calvin cycle (light-independent reactions of photosynthesis).

Explanation:

Photosynthesis is defined as the process in which green plants and certain bacteria in the presence of sunlight manufacture their food. The organic molecule is converted into glucose in the presence of carbon dioxide, water, and sunlight. Photosynthesis is the process in which oxygen is yielded as the by-product. Photosynthesis is the type of oxidation-reduction reaction. Carbon dioxide undergoes reduction, whereas water undergoes oxidation.

Kreb's cycle or citric acid cycle is an important step in the cellular respiration. The process occurs in the mitochondrial matrix, where the acetyl coenzyme A (decarboxylated pyruvate) is broken down into $\text {CO}_{2}$ and $\text H_{2} \text {O} }$.

Calvin cycle or the light-independent reactions of photosynthesis involves the fixation of carbon dioxide into sugar molecules. The process takes place in the thylakoid membrane, which results in the formation of ATP and NADH. The process occurs in the absence of sunlight.

Light-dependent reactions of photosynthesis involve the conversion of light energy into chemical energy. The process occurs in the presence of oxygen, within thylakoids.

Chemiosmosis involves the movement of ions across the membrane. It results in the generation of an electrochemical gradient. This electrochemical gradient drives the process of ATP synthesis.

Glycolysis occurs in prokaryotes and eukaryotes, which involves the breakdown of glucose to yield energy. It is an important step in the respiration process. The end-product of glycolysis is pyruvate, which is then incorporated into several cycles to extract energy.
