Anaerobic respiration releases more energy from glucose tan aerobic respiration.c. There maybe insuffiecient oxyen supplied to the muscle cells.d. Carbon dioxide builds up in the respiring muscle cells.
Mark the following statements as true or false. If a statement is false, correct it to make a true statement. a. Stored ATP and creatine phosphate are immediate energy sources for muscle fibers. b.
