MUSCLE PHYSIOLOGY

Detailed explanation-1: -Sarcoplasm is the cytoplasm of a muscle fibre. It is a water solution containing ATP and phosphagens, as well as the enzymes and intermediate and product molecules involved in many metabolic reactions.

Detailed explanation-2: -Sarcoplasmic Organelles The abundant sarcoplasm (i.e., cytoplasm) within the core of the myotube between and around nuclei contains membranous organelles. These are mitochondria with well-formed cristae, Golgi apparatuses generally located at the end of a nucleus, and single-membrane vesicles.

Detailed explanation-3: -The sarcoplasm contains myoglobin, a hemoprotein that reversibly binds oxygen and functions as a molecule for storage and transport of O2 within the muscle.
