(b) They derive energy from aerobic processes

(c) They are not rich in myoglobin

(d) They contain fewer mitochondria than red fibres

This question was posed to me by my school teacher while I was bunking the class.

Answer 1

Correct answer is (b) They derive energy from aerobic processes

Easiest explanation: Muscles contain red fibres and white fibres. The white fibres are rich in sarcoplasmic reticulum. They contain a small number of mitochondria and myoglobin. They derive energy from anaerobic processes.
