ATP production would increase since glycolysis would be using less ATP. The Krebs cycle production of FADH2 would increase. O The Krebs cycle would continue to function at a normal rate. O The Krebs cycle production of NADH would decrease.
Which statement is not completely true? O Stage 3 is composed of the citric acid cycle, and the elecrtron transport chain coupled with oxidative phosphorylation. O Anabolism are reactions involved in the breakdown of biomolecules energy is released. O The ultimate goal of the 3 stages of catabolism is to regenerate ATP from ADP. O In Stage 2 of Catabolism, the main energy molecule that all macronutrients are broken down into is Acetyl groups (combined with the shuttle CoA) to form Acetyl COA. O An array of chemical reactions (series of steps) that are organized into orderly well regulated sequences are called metabolic pathways. O The purpose of the citric acid cycle is to regenerate NAD* and FAD to NADH and FADH2
Choose all of the following true statements. Hint: 6 statements are true. □ If an electron moves from an atom of higher electronegativity to an atom with lower electronegativity, energy is released. O Glycolysis occurs with or without oxygen present. Other biomolecules such as lipids, disaccharides, and proteins can enter the biochemical pathway of aerobic respiration just not directly into the first step of glycolysis. Molecules other than glucose can be broken down and used to build up ATP in aerobic respiration. Glycolysis occurs during both alcohol and lactic acid fermentation, producing 2 net ATP. The higher the electronegativity of an atom, the tighter it holds an electron and the lower its potential energy. Water is the final electron acceptor of the ETC in aerobic respiration. Each protein component of the ETC in aerobic respiration is more electronegative than the last.
How much fat (in grams) would the body have to burn to produce the daily minimum requirement of 40 kg ATP from ADP and phosphate? Assume that: 1. The fat is metabolized completely to water and carbon dioxide. 2. The energy that is released can be used entirely for ATP production. 3.
