Which part of the chloroplast contains enzymes for carbohydrate and protein synthesis?

Option: 1


Option: 2


Option: 3


Option: 4


Answers (1)


The stroma of the chloroplast includes enzymes essential for glucose and protein synthesis. Enzymatic processes in the stroma produce sugar, which is then converted into starch. It also has ribosomes and tiny, double-stranded circular DNA molecules. Hence option 3 is the correct answer.

Explanation for the incorrect  options :

Option 1 is incorrect because thylakoids are in charge of producing ATP (Adenosine Triphosphate), as well as assisting in the electron transport chain and promoting water photolysis. These reactions and activities in the plant cell are critical because they create energy for the plant cell to survive.

Option 2 is incorrect because grana's primary job is to carry out the photosynthetic process. Grana (thylakoid membrane, to be exact) is the site of photosynthetic light reactions. Grana stacks are extremely sensitive to the development of light responses.

Option 4 is incorrect because the function of chlorophyll in a plant is to absorb light, mainly sunlight. The light energy is delivered to two types of energy-storing molecules. The stored energy is used by the plant to transform carbon dioxide (absorb from the air) and water into glucose, a type of sugar.
