Answer
Option d:All of the above
Work Step by Step
ATP production in muscle fibres occurs by three ways:
✓Aerobic respiration:Occurs during prolonged and moderate muscle activity.
✓Lactate fermentation:Occurs mostly during exercise by conversion of pyruvate to lactate,less ATP is produced.
✓Creatine phosphate breakdown:Muscle fibres store creatine phosphate and later forms ATP by transferring a phosphate group to ADP.
