‘A structure in the sarcoplasm responsible for aerobic energy production’

A	Mitochondria
B	Myoglobin
C	Phosphocreatine
D	None of the above

Explanation:

Detailed explanation-1: -In skeletal muscle, the sarcoplasmic reticulum (SR) is the primary regulator of calcium storage, release, and reuptake while glycolysis and the mitochondria are responsible for cellular ATP production.

Detailed explanation-2: -Mitochondria were called sarcosomes by Kolliker and bioblasts by Altman. Other names proposed were chondrisomes, chondriomites and plastochondria. Term Chondriome includes all mitochondria of a cell.

Detailed explanation-3: -The cytoplasm of a muscle cell or fibre (the sarcoplasm) contains all the usual subcellular organelles, including many nuclei and mitochondria.

Detailed explanation-4: -Skeletal muscle cells have high energy requirements, so they contain many mitochondria in order to generate sufficient ATP.
