Part A Explain the rationale for the production of ketone bodies during starvation. During starvation, glucose is in short supply, and the body responds by producing ketone bodies as a source of energy During starvation, the oxygen concentration in blood drops and the body responds by metabolizing nutrients to less oxidated compounds such as ketone bodies. proton concentration high enough to maintain ATP synthesis by ATP synthase. During starvation, pH gradient decreases and the body have to produce acidic ketone...

Which of the following statements regarding catabolic pathways are true? 1. When proteins are used as a source of energy for the body, the proteins are first broken down to produce amino acids, which are then converted into either glyceraldehyde 3 phosphate or acety CoA The enzyme phosphofructokinase is subject to allostericinhibition by high levels of citric acid When acety CoA builds up in the call it increases the activity of the enzyme that synthesizes oxalacetato from pyruvate and carbon...
