Muscular System: Muscle Metabolism

1. List the three roles of adenosine triphosphate in muscle contraction1. Energize the fount stroke of the myosin cross bridge.2. Disconnecting the myosin manoeuver from the binding site on actin at the conclusion of a power stroke.3. Energizing the calcium ion pump.2. The potential susceptibility in adenosine triphosphate is released when the storage high-energy bond is broken by a process called hydrolysis. write the end products of this process adenosine triphosphate (+ H2O) ( ADP3. Rebuilding ADP into adenosine triphosphate with a new source 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 cycle and aerobic phosphorylation5. An immediate source of energy is creatine phosphate (CP), but the supplies are limited and speedily scummy. One molecule of CP produc es one ATP.6. Glucose is a major source of energy for synthesizing ATP. List the two sources of glucose1. Glucose enters the muscle stall 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. Name two products of the segmentation of glucose1. Two ATP molecules2. Pyruvic acid If oxygen is not available, pyruvic acid is born-again to lactic acid, which is the end product of anaerobic respiration.8. If oxygen is available, the process is know 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 4 processes that occur during this time1. Lactic acid is converted back 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. localise the following characteristics under the correct fiber type in the mesa belowKrebs cycle and oxidative phosphorylationuses glycolysis fatigue rapidlyhigh natural selection few capillariesmany capillaries lots myoglobinlittle myoglobin long-distance runnersprinter Krebs cycle and oxidative phosphorylation uses glycolysis fatigue rapidly high endurance few capillaries many capillaries much myoglobin little myoglobin long-distance runner sprinter light-headed in color, large diameter red in color, small diameter.
