Where does the energy for glycolysis come from?
Where does the energy for glycolysis come from?
Kevin Cann. It lasts from roughly ten seconds into physical activity up to about two to three minutes. The energy for glycolysis comes from glucose, or our stored form of glucose – glycogen. Glycogen is stored in muscle tissue and the liver, and the average person holds about 1,500-2,000 calories of stored glycogen.
Which is the primary fuel for cellular respiration?
During glycolysis, a glucose molecule is cleaved in two, creating two pyruvate molecules and the energy molecule, ATP. The pyruvate molecules are shuttled quickly into the mitochondria, where they are used in the remainder of the respiration process. The glucose molecule is the primary fuel for cellular respiration.
What are the steps of the anaerobic glycolytic system?
Steps of the anaerobic glycolytic system: Initially stored glycogen is converted to glucose. 2 ATP are used to fuel glycolysis and 4 are created so the body gains 2 ATP to use for muscular contraction. The breakdown of glucose to synthesise ATP results in the creation of a substance called ‘pyruvate’ and hydrogen ions.
How are ATP and pyruvate used in the aerobic system?
2 ATP are used to fuel glycolysis and 4 are created so the body gains 2 ATP to use for muscular contraction. Pyruvate is created as the end product of the breakdown of glucose. As oxygen is present pyruvate is converted into a substance called ‘acetyl coenzyme A’.

What are the breakdown products of anaerobic glycolysis?
Anaerobic glycolysis is an inefficient means of ATP production from glucose and leads to raised concentrations of adenosine and of its breakdown products, including hypoxanthine and xanthine, which are substrates for the xanthine dehydrogenase enzyme system.
What are the sources of fuel for the lactic acid system?
Sources of fuel for the anaerobic/lactic acid system includes complex carbohydrates. The lactic acid system specifically uses a stored carbohydrate known as glucose.
