Question

The cytoplasm within the muscle fiber is known as the

• A. myoglobin component
• B. sarcolemma
• C. sarcoplasm
• D. sarcoplasmic reticulum

Answer 1

The correct option is C

sarcoplasm

Sarcoplasm is the cytoplasm of a myocyte (muscle fiber). It is comparable to the cytoplasm of other cells, but it contains unusually large amounts of glycosomes (granules of stored glycogen) and significant amounts of myoglobin, an oxygen-binding protein. Sarcolemma is the name of the cell membrane that encloses each muscle cell.
