Processes of Chemical Changes in Muscles | Humans | Biology
Following chemical changes take place during contraction in the anaerobic and aerobic phases in human body. 1. Glycolysis and Oxidative Breakdown: This process involves many separate enzymes and different intermediates. The end products are pyruvic or lactic acid. The first step in the liberation of energy for contraction is the breakdown of glycogen in the muscle fibre. The glycogen reacts [...]
