Question

Which organelle is abundant in red fibres of muscles?

(a) Sarcoplasmic reticulum

(b) Nuclei

(c) Mitochondria

(d) Peroxisomes

This question was addressed to me by my college professor while I was bunking the class.

Origin of the question is Locomotion & Movement in section Locomotion and Movement of Biology – Class 11

Answer 1

Correct choice is (c) Mitochondria

For explanation I would say: Red fibres of muscle are rich in mitochondria as produce energy in the form of ATP. Red fibres are also rich in myoglobin, which is a red coloured protein that has the function of oxygen storage.
