WebbFuels for the heart are fatty acids, ketone bodies, and lactic acid taken from the blood. Evidently when the source of lactic acid is the blood, the heart does not take it up any faster than it can convert it to pyruvate (and then to AcCoA, etc.) Since aerobic metabolism is so important for the heart, is has a high content of mitochondria. WebbGlycolysis (anaerobic) System. Another system that doesn’t require oxygen is glycolysis, also known as the lactate system. This system provides enough ATP to fuel 1 to 3 minutes of intense activity when adequate oxygen isn’t available for aerobic metabolism. Lactate or lactic acid is something that most runners have heard of and may even ...
