Reactions that require carbon dioxide take place in the calvin cycle alone
Answer: Option D
<u>Explanation:</u>
Calvin cycle is an important cycle that plays a major role in the synthesis of starch through the photosynthesis. Calvin takes place as a part of the dark reaction in the stroma.
It is the calvin cycle that requires carbon dioxide. It uses the ATP that are produced by the light reaction that takes place in the thylakoid with the help of chlorophyll that traps the sunlight.
This process is called meiosis. Mitosis produces two identical daugheter cells, each with 12 chrimosomes. Meiosis produces four daughter cells with 6 chromosomes.
The major food molecule in living organisms is a sugar called glucose. Most carbohydrates (sugars and starches) are converted into glucose before they are broken down in the cytosol to release energy. ... If oxygen is present, then glucose can be broken all the way down into carbon dioxide and water.
