aerobic energy system

Question 1

How does the aerobic energy system work?

Answer 1

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

Question 2

lipolysis

Answer 2

breakdown of fat
(lipo- fat
lysis- breakdown)

Question 3

describe the process of lipolysis

Answer 3

triglyceride-> fatty acid-> krebs cycle-> electron transport system

Question 4

Aerobic glycolysis

Answer 4

When carbohydrates are used as the fuel for the aerobic system

Question 5

How is the aerobic system different from the anaerobic?

Answer 5

• 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

Question 6

What can compromise the removal of byproducts in aerobic respiration?

Answer 6

• usually easily removed
• removal of heat and water through sweat can be compromised in conditions of high temperature/ humidity

Question 7

Aerobic energy production when muscles are at rest (equation)

Answer 7

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
