How does the aerobic energy system work?
uses oxygen to drive the complete breakdown of glucose/ fats/ protein, using the processes of, glycolysis, lipolysis, krebs cycle, electron transport system after pyruvic acid-> krebs cycle-> electron transport system–> glucose completely metabolised
lipolysis
breakdown of fat (lipo- fat lysis- breakdown)
describe the process of lipolysis
triglyceride-> fatty acid-> krebs cycle-> electron transport system
Aerobic glycolysis
When carbohydrates are used as the fuel for the aerobic system
How is the aerobic system different from the anaerobic?
• The first steps for glycogen and glucose are the same as for the LA system. • Fats and proteins can also be used as a fuel source. • Oxygen is required. • By-products are produced, but these are non-fatiguing
What can compromise the removal of byproducts in aerobic respiration?
• usually easily removed • removal of heat and water through sweat can be compromised in conditions of high temperature/ humidity
Aerobic energy production when muscles are at rest (equation)
Fuel: 1/3 glucose from muscles and liver, 2/3 fats *triglycerides and fatty acids) from blood Oxygen breathed in —> (with enzyme assistance) • CO2 breathed out • Water as water vapour and in sweat and urine • heat • Energy used to combine ADP and phosphate into ATP
