Why a red muscle fibre can work for a prolonged period while a white muscle fibre suffers from a fatigue after a short period?

Study of following a. The accumulation of pyruvic acid in the muscle cause fatigue B. ATP is resynthesized in the muscle by the phosphorylation of ADP by a phosphagen. C. Cori and Cori cycle occurs in the liver D. The phosphagen in the vertebrate muscle is arginine phosphate. The correct set of answers for muscle contraction is

Why the white skeletal muscles undergo earline fatigue than the red skeletal muscles?

Assertion : During exercise, a person undergoes fatigue very soon. Reason : During this period , muscle fibres undergo oxygen debt.

Assertion: A parson undergoes fatigue very soon during exercise. Reason : Muscle fibres undergo oxygen debt during exercise.

Answer the following briefly : (a) How does the muscle shorten during its contraction and lengthen during its relaxation ? (b) What biological functions are served by the skeletal system ? (c ) What type of muscles will be antagonistic to pronators and abductors respectively, and why ? (d) Why a red muscle fibre can work for a prolonged period while a white muscle fibre suffers from fatigue after a shorter work? (e ) Where from the muscle gets energy for its contraction ?
