Answer 1

Explain how the body metabolizes carbohydrates and amino acids in the short term fasting states (prior to using up all your glycogen)

Answer:

During the short term fasting glucose levels start to deplete, glycolysis will shut off in cells and fatty acids are converted into acetyl CoA and make ATP through krebs cycle. Pyruvate, lactate, and alanine from muscle instead of entering into krebs cycle goes to the liver for glucose synthesis. Glycerol from fatty acid can be used as a source for gluconeogenesis. Ketones are also produced from fatty acids and triglyceride stores for gluconeogenesis.
