- When proteins are used as a source of energyfor the body, the proteins are changed into glucose molecules and fed into Glycolysis. A) true
- From the process of Glycolysis through to the end of the Citric Acid cyclemost of the energy remaining from the original glucose molecule that makes ATP is stored in molecules of NADH+H+ A) true
Proteins are source of gluconeogenic substrates and during fasting or starvation, then proteins can be used to generate more glucose which can then be used in cellular respiration. Some amino acids can enter the cellular respiration process as pyruvate.
The process of cellular respiration has three main stages: Glycolysis, TCA and ETC. Gylcolysis forms 2 ATP molecules and a pyruvate molecule which enters TCA as acetyl CoA which then produces NADH and 2 more ATP molecules. After this, the only molecule that enters the last stage of cellular respiration is the electron carriers (NADH) which provide more ATP than the other steps.
