What would be a likely consequence if step 4 of the citric acid cycle no longer operated far from equilibrium, and instead occurred near equilibrium? the step would need to be coupled to ATP hydrolysis none of these possibilities are likely this step would no longer be a highly regulated step the reaction would no longer occur
Sonicating a suspension of mitochondria produces submitochondrial particles derived from the innermitochondrial membrane. These membranous vesicles seal inside out, so that the intermembrane space of themitochondria becomes the lumen of the submitochondrial particle. Explain (or diagram) the process of electrontransfer and oxidative phosphorylation in these particles. Assuming all the substrates for oxidativephosphorylation are present in excess, does ATP synthesis increase or decrease with an increase in the pH ofthe fluid in which the submitochondrial particles are suspended? Why?
Multiple choice Ultimately, the goal of cellular respiration is to strip electrons from glucose. These stripped electrons are used to generate the energy in oxidative phosphorylation that is needed to: -Actively transport H+ into the intermembrane space -Actively transport NAD+ into the intermembrane space -Turn on ATP synthase -Allow H+ to diffuse down its concentration gradient into the mitochondrial matrix
MON TRANSPORT CHAIN Intermembrane Space 3 ACP Mitochondrial Matrix FADH FAD Copyrighs 0200n Benmin Cummings an impii s Addson identify the importance to keep the electrons (e-) running through the electron transport chain. The electrons move to and join with ADP to form ATP Electron movement causes the body to take in axygen. The electrons will flow through ATP Synthase in order to make ATP The energy of the moving electrons will power the transport of H+ to the intermembrane space. Next Previous 00
Concept 9.5: Fermentation and anaerobic respiration enable cells to produce ATP without the use of oxygen•Most cellular respiration depends on electronegative oxygen to pull electrons down the transport chain.•Without oxygen, the electron transport chain will cease to operate.Inthat case, glycolysis couples with anaerobic respiration or fermentation to produce ATP.•Anaerobic respirationuses an electron transport chain with a final electron acceptor other than oxygen, for example, sulfate.•Fermentationuses substrate-level phosphorylation instead of an electron transport chain to generate ATP.•Types of Fermentation, oIn alcohol fermentation, pyruvate is converted to ethanol in two steps(Figure 9.17)▪The first step releases CO2from pyruvate▪The second step produces NAD+and ethanol.▪Alcohol fermentation by yeast is used in brewing, winemaking, and baking.▪Reaction summary: Inputs _____ ______ _____Products _______ ______ _______oIn lactic acid fermentation, pyruvate is reduced by NADH,…

O Glycolysis is part of fermentation. Question 12 Which of these is a correct statement about energy-yielding pathways in bacteria? O Anaerobic respiration is the only pathway in aerotolerant anaerobes (no aerobic respiration or fermentation). O Fermentation makes less ATP compared to aerobic respiration, but more ATP compared to anaerobic respiration. O Aerobic respiration, anaerobic respiration, and fermentation all occur in facultative anaerobes. O Fermentation is the only pathway in obligate anaerobes (no aerobic or anaerobic respiration).
