However, when oxygen is present in a very less quantity inside the muscle cells, they temporarily convert pyruvate into a substance called lactate, which allows glucose breakdown for energy. This is also called as anaerobic energy production and as a result lactic acid is accumulated inside the muscle cells. Well, I was gasping because, I needed more oxygen to supply to my body cells for aerobic respiration and my legs were shaking because of a freight hormone, adrenaline – it is released when one feels some kind of fear, for example, examination fear in this case. In addition, the lactic acid accumulation increases the acidity of the muscle cells and disrupts other metabolites, and the muscle strains occur.
2.Deltoid is a three-headed muscle that caps the shoulder. The three heads are anterior, lateral and posterior heads.
