Which part of the chloroplast contains enzymes responsible for the synthesis of carbohydrates and proteins?
Thylakoid
Stroma
Granna
Inner membrane of the chloroplast
The stroma of the chloroplast contains enzymes required for the synthesis of proteins and carbohydrates. Ribosomes and tiny, circular, double-stranded DNA molecules are also present. Hence, the correct answer is option 2.
Explanation for the incorrect options:
Option 1 is incorrect because the photochemical or light-dependent processes of photosynthesis take place in the thylakoid.
Option 3 is incorrect because the execution of the photosynthetic process is the grana's primary function. The photosynthetic light processes take place in the grana (more specifically, in the thylakoid membrane). The growth of light responses triggers a strong response from the grana stacks.
Option 4 is incorrect because the inner membrane of chloroplast plays a crucial role in the transport of electrons and the chemiosmotic synthesis of ATP in chloroplasts.
