Equation for Cellular Respiration: (Sharata, 2011).

Aerobic and Anaerobic Respiration

Aerobic respiration happens when glucose reacts with oxygen; it takes place in the mitochondria. For one molecule of glucose aerobic respiration produces 38 ATP, anaerobic only produces 2 ATP molecules. The end product of aerobic respiration is carbon dioxide and water and the end product of anaerobic respiration is ethyl alcohol or lactic acid and carbon dioxide. Therefore, aerobic respiration produces significantly more ATP than anaerobic respiration. (Scoville, 2014).

Effects of Exercise on Cardiovascular and Respiratory System

When you begin exercising your energy requirements increase instantly, the increased demand places stress on the cardiovascular and respiratory system to deliver more oxygen to working tissue cells and to remove carbon dioxide to remove carbon dioxide and other waste from tissue cells. (Ohara 2009). Blood flow must increase and the heart must pump more blood. Regular exercise results in increased cardiac output, this results in an improved delivery of oxygen to active muscles. The more you exercise the more efficient cardio-respiratory system becomes at supplying oxygenated blood throughout your body. Exercise can also form an addiction, which could also be detrimental to your health. (Kochen, 2014).

Excessive exercise can have an adverse effect on the heart, scarring, enlargement and stiffening of the heart can occur with excessive training. There could be an increased risk of stroke and possibly developing heart rhythms. (Web MD, 2005-2014). Also you could suffer from exercise induced asthma or a condition know
