Muscular System: Muscle Metabolism

1. List the three roles of adenosine triphosphate in brawn contraction1. Energize the power stroke of the myosin dumbfound bridge.2. Disconnecting the myosin head from the binding site on actin at the conclusion of a power stroke.3. Energizing the calcium ion pump.2. The potential energy in adenosine triphosphate is released when the terminal laid-back-energy bond is broken by a surgical procedure called hydrolysis. Write the end products of this attend to adenosine triphosphate (+ H2O) ( adenosine diphosphate3. Rebuilding automatic data cognitive operationing into ATP with a new fount of energy is carried out by a process called dehydration synthesis.Write the equation for this process ADP ( ATP (+ H2O)4. List the three processes used to synthesize additional ATP when ATP supplies are low1. Hydrolysis of creatine phosphate2. Glycolysis3. The Krebs musical rhythm and oxidative phosphorylation5. An contiguous source of energy is creatine phosphate (CP), but the supplies are control and rapidly depleted. One molecule of CP produces one ATP.6. Glucose is a major source of energy for synthesizing ATP. List the dickens sources of glucose1. Glucose enters the muscle cell directly from the blood.2. Glucose is produced by hydrolysis of glycogen stored in the muscle cell.7. Glycolysis is the process that breaks down glucose. severalize two products of the breakdown of glucose1. Two ATP molecules2. Pyruvic erosive If oxygen is not available, pyruvic acid is converted to lactic acid, which is the end product of anaerobic respiration.8. If oxygen is available, the process is known as ___aerobic_ respiration. Name two sources of oxygen1. Oxygen enters the muscle cell directly from the blood.2. Oxygen is stored in myoglobin, an oxygen-binding protein.The aerobic pathway consists of glycolysis + krebs cycle + oxidative phosphorylation. The net result of one glucose molecule is 36 ATP.9. The process of restoring depleted energy reserves after exercise is called repaying the oxygen debt. Name four processes that occur during this time1. Lactic acid is converted corroborate to pyruvic acid, which enters the Krebs cycle, producing ATP.2. This ATP is used to rephosphorylate creatine into creatine phosphate.3. Glycogen is synthesized from glucose molecules.4. Additional oxygen re-builds to myoglobin.10.
