Which statements describe electron transport chain events?NADH releases two hydrogen ions and donates two electrons to coenzyme Q.ATP synthase uses the energy from the redox reactions to generate ATP.Citrate metabolism results in the formation of one FADH2 and three NADH.Two electrons pass between cytochromes through a series of redox reactions.IncorrectMacmillan Learning<Feedback> Attempt 2One of the statements you selected isincorrect. The high-energy moleculesthat donate their electrons are producedby the citric acid cycle, not the electrontransport chain.

The electron transport chain is a system of four protein complexes that oxidise NADH/FADH2 and…

Base from the diagram 1. what is the final electron acceptor of the electrons removed from the intermeddiate compounds in the glucose and catabolism? 2. what is the process in the electron transport chain that makes us energy from a proton gradient to make ATP? 3. What is the function of ATP synthase in the last stage of cellular respiration?
Show how the reactions of the electron transport chain differ from those in Question 3 when FADH2 is the starting point for electron transport. Show how the reactions that liberate enough energy to drive the phosphorylation of ADP differ from the pathway when NADH is the starting point

Look at the image of the electron transport chain below. Using the information provided in the picture only, in 4 or more sentences explain what is occurring. In your answer you must mention: electrons (e), NADH, FADH2, H* ions, ATP synthase and ATP. mitochondria ELECTRON INPUT electrons from TRANSPORT Kreb's Electron Cycle Transport NADH and FADH2 OUTPUT 34-36 ATP H+ H+ H* H' H+ ELECTRON TRANSPORT CHAIN ATP SYNTHASE H' ADP ATP NADH FADH, H.
The image below shows part of a key catabolic pathway. If an individual had a deficiency for the enzyme required at point "X", would they still be able to produce a high rate of ATP during very strenuous exercise? ATP in Glucose Prep. phase Payoff phase ļ - MacRoc Pyruvate →→→ Anaerobic fate of pyruvate ATP out ▬OD OF 1- HP 01 -- Select one: O a. No, because NAD* will not be regenerated by lactate dehydrogenase. The reduction of NAD+ to NADH is a required step during the payoff phase of glycolysis. O b. No, because lactate dehydrogenase is required for the continued recycling of NAD+ to NADH, thus allowing glycolysis to continue. Oc. Yes, because pyruvate dehydrogenase is necessary to produce acetyl-CoA, which under these conditions will feed into the citric acid cycle. Od. Yes, because this enzyme is responsible for the substrate-level phosphorylation necessary to maintain the ATP input for the preparatory phase of glycolysis.

Which statement is FALSE? Cytochrome c2 transfers the electrons from QH2 to complex bc1 The proton gradient drives the synthesis of ATP through the action of ATP synthase Complex bc1 is homologous to Complex III of the respiratory electron-transport chain the cytochrome subunit of the reaction center must regain an electron to complete the cycle After the waste of a valuable high-energy electron the absorbed light energy can be converted into heat
First, you should map out all of the biochemical stages and processes in cellular respiration and photosynthesis. This means all of the stages are unpacked in-depth (light-dark Calvin Krebs glycolysis) into stages, their inputs (reactants), outputs (Products), and interdependent molecules (connected molecules). Add more detail to the mind map below about cellular respiration and photosynthesis. (Also added an extra image of what the level of detail should be.)
When muscles contract, a chain of events result in greater activity by the TCA cycle. All of the following are links in that chain EXCEPT: The ADP concentration increases. Rate of respiration and oxygen consumption increases. The electron transport chain produces more water. The concentration of NADH decreases and the concentration of NAD+ increases. 2) (True or False )______The concentration of oxaloacetate drops and TCA cycle is halted which leads to the synthesis of ketone bodies. 3) NADPH is used for: a) Oxidizing vitamin E b) Oxidizing glutathione c) Reductive biosynthesis of fatty acids d) β-oxidation of fatty acids
The complete oxidation of glucose to carbon dioxide and water has a Δ G of -2870 kJ/mol glucose. Aerobic respiration captures about 930 kJ of this energy. What happens to the rest of the energy? Question 34 options: it is used for the chemiosmotic pumping of protons it is lost as heat and an increase in entropy it Is used in active transport it is used to synthesize NADH it is used for substrate-level phosphorylation
