- please help with this question. I am stuck. I listed the graph below ! Exergonic reactions such as the breakdown of ATP, are said to be “spontaneous.” However, by themselves, even exergonic reactions often proceed very slowly. What part of the curve helps to explain this?CHOOSE THE CORRECT LETTER Hydrolysis of ATP yieldsA.-30.5 kJB. -30.5 kcalC.30.5 kJD. 30.5 kcalTrue or False compared with NAD+, electrons transferred to FAD lead to less proton translocation in the electron transport chain I chose FALSE and it was incorrect. Since the correct answer is TRUE, explain why it is so i can better understand where i went wrong
- Please answer this question in detail because I don't understand it. Thank you. Which of the following best describes the role of chemiosmosis in oxidative phosphorylation? (A) Chemiosmosis is the movement of electrons down their electrochemical gradient, which generates energy in the electron transport chain. (B) Chemiosmosis is the chemical breakdown of ATP into ADP and inorganic phosphate. (C) Chemiosmosis is the movement of chemicals dissolved in water down their concentration gradient, across the mitochondrial membrane. (D) Chemiosmosis is the chemical breakdown of water into hydrogen and oxygen ions at the final stage of the electron transport chain. (E) Chemiosmosis is the movement of ions down their electrochemical gradient, which generates ATP.Briefly outline the electron flow in oxidative phosphorylation to describe how its function is directly coupled to ATP synthesis. Be sure to include where the electrons that feed into oxidative phosphorylation come from in your answer.Which of the following statements are correct? Explain your answers.A. Many, but not all, electron-transfer reactions involve metal ions.B. The electron-transport chain generates an electrical potential across the membrane because it moves electrons from the intermembrane space into the matrix.C. The electrochemical proton gradient consists of two components: a pH difference and an electrical potential.D. Ubiquinone and cytochrome c are both diffusible electron carriers.E. Plants have chloroplasts and therefore can live without mitochondria.

E. electrons moving through the electron transport chain, proton gradient 77. The product of photosystem I is A. ANDPH B. Water C. ATP. D. glucose E. NADHPlease answer fast The equilbrium constant (Keq) under standard conditions for the hydrolysis of ATP is 200,000 M. This would suggest the reaction is: 1. proceeding in reverse direction 2. proceeding in forward direction 3. in equilibrium However, this does not take into consideration the concentration of substrates/products within the cell. This is can be calculated by determining the reaction quotient, Q by: [ATP] x [Pi] / [ADP] [ATP] + [Pi] / [ADP] [ADP] x [ATP] / [Pi] [ADP] x [Pi] / [ATP] Biochemical reactions commonly involve the transfer of groups from ATP. What is one of the products of pyrophosphate cleavage from ATP? AMP Adenosine ADP Inorganic phosphate Q5-6. The hydrolysis of ATP is often coupled to other reactions. For example: Phosphoenolpyruvate (PEP) + H2O → Pyruvate + Pi (ΔG'° = -63.1 kJ/mol) ATP + H2O → ADP + Pi (ΔG'° = -30.5 kJ/mol) (The standard free-energy changes for the reactions are indicated in brackets) Q5. Given the information above, what is the…Choose the correct answer from the options in brackets. The [positive/negative] standard free‑energy change favors the oxidation of succinate by covalently‑bound FAD. This is consistent with K′eq [ >1 / =1 / <1 ]. Oxidation by NAD+ would require a large, [positive/negative] standard free‑energy change, with K′eq favoring the synthesis of succinate.
