why can the citric acid cycle not function without the electron transport chain?

Expert Solution

The Krebs cycle is a series of reactions which occurs in the mitochondria and results in the formation of ATP and other molecules which undergo further reactions to form more ATP.
The electron transport chain is the final stage of aerobic respiration. It utilizes the molecules of NADH and FADH2 formed during glycolysis and the Krebs cycle to produce great amounts of ATP. During glycolysis and the Krebs cycle, the NAD+ and FAD coenzymes were passed high energy electrons. The purpose of the electron transport chain is to pass those electrons to other carrier molecules which hold the electrons at slightly lower energy levels. As the electrons are passed from high to low energy levels, energy is released. After many steps, the electrons are finally accepted by oxygen at the lowest energy level, producing water.
in these crebs cycle there will be oxidation reduction reactions by transfer of electrons so electron transport chain required to citric acid cycle

Glucose Catabolism 1) Aerobic cellular respiration Glycolysis, Citric Acid cycle, Electron Transport Chain etc. 2) Anaerobic Respiration 3) Fermentation Name the three major pathways for glucose catabolism (on the top ^) and briefly describe them (names of major step, inputs, outputs). For inputs and outputs, consider both carbon-based molecules and energy-containing molecules. For each pathway, discuss: An example of a final electron acceptors for each pathway The relative electronegativity of the final electron acceptor (comparing the 3 pathways) Relative amount...

From these pathways, the TCA cycle, electron transport chain, oxidative phosphorylation, β-oxidation for fatty acid degradation, ketone body metabolism, and lipid biosynthesis which ones are affected by low oxygen? Where in the cell do these pathways occur? Next, explain how reduced oxygen slows each pathway(s) identified. Once oxygen is no longer limiting, energy production resumes. Explain how the concentration of ATP increases with the availability of oxygen (detailed pathways and structures are NOT required). Next explain in detail how ATP...

inThe citric acid cycle there are three reactions of the citric acid cycle it's self that are regulated: -citrate synthase which is where ATP inhibits in in citeo -isocitrate dehydrogenase: alosterrically activated by Ca2+ and ADP also is inhibited by NADH - alpha ketoglutarate dehydrogenase which is where Ca2+ increases the rate of formation of succinyl-CoA what would happen if all three of these reactions were not present? what would happen if citrate synthase was not functioning, what would happen...
