NEET · Biology · STD 11 - 12. Respiration in plants

Cytochromes are found in

A cristae of mitochondria
B lysosomes
C matrix of mitochondria
D outer wall of mitochondria.

Verified Solution

Answer & Solution

Correct Answer

(A) cristae of mitochondria

Step-by-step Solution

Detailed explanation

(a) : Cytochrome is a group of proteins, each with an iron containing haeme group. They are a part of electron transport chain in mitochondria (present in cristae) and chloroplasts (in thylakoids).

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
