Because an inadequate supply of blood will not provide enough oxygen to keep up with the energy demands of contraction.
For muscles to contract there needs to be an adequate supply of ATP within the cell. ATP is generated in part by a supply of glucose and oxidative phosphorylation. An in … adequate supply of blood will not provide enough oxygen to keep up with the energy demands of contraction. 12 people found this useful. Slow twitch muscles fibres contract slowly and are small in diameter. They have a rich blood supply for oxygen delivery and lots of mitochondria, meaning they are very resistant to fatigue. Slow twitch muscle fibres react slowly to the neural stimulation that signals initiation of muscular contraction. Confidence votes 4.9K. For muscles to contract there needs to be an adequate supply of ATP within the cell. ATP is generated in part by a supply of glucose and oxidative phosphorylation. An inadequate supply of blood will not provide enough oxygen to keep up with the energy demands of contraction. For muscles to contract there needs to be an adequate supply of ATP within the cell. ATP is generated in part by a supply of glucose and oxidative phosphorylation. An inadequate supply of blood will not provide enough oxygen to keep up with the energy demands of contraction. Why is oxygen necessary for muscles to work;Energy to allow the muscle to contract is produced by respiration (respiration occurs in the mitochondria). Aerobic respiration takes oxygen and glucose and converts them into energy, water and carbon dioxide. The coronary arteries are responsible for carrying oxygen-rich blood to the heart. However, most oxygen-rich blood is being carried away from the heart, meaning that most arte … ries are not carrying blood into the heart at all. Coronary Arteries. Because the heart is composed primarily of cardiac muscle tissue that continuously contracts and relaxes, it must have a constant supply of oxygen and nutrients. The coronary arteries are the network of blood vessels that carry oxygen-and nutrient-rich blood to the cardiac muscle tissue.
