Detailed explanation-1: -Although the primary source of ATP in aerobic metabolism is carbohydrates, fatty acids and protein can also be used as fuel to generate ATP.
Detailed explanation-2: -The graph shows that from the start of exercise the ATP PC system provides the majority of the energy but as time progresses the Lactic Acid system will become predominant followed by the aerobic system.
Detailed explanation-3: -Source of Fuel – The aerobic system can use CHO, fats, and protein as its source of fuel, though protein is used sparingly. The aerobic system uses aerobic glycolysis, the Krebs cycle and the electron transport chain in its production of ATP.
Detailed explanation-4: -Carbohydrates are the most versatile fuel source available to supply energy for ATP resynthesis. Carbohydrates in the form of glycogen can provide the energy for ATP resynthesis under both anaerobic (no oxygen required) and aerobic (oxygen required) conditions.
