Is associated with an enzyme and not a mobile electron carrier c. Serves to facilitate redox reactions d. s an electron carrier in the TCA cycleWhen NAD picks up two electrons and a proton in reactions of the Krebs cycle to form NADH, the NAD+ isWhich of the following statements about oxidation-reduction (redox) reactions is correct? A) The molecule that is oxidized loses electrons and is the oxidizing agent. B) The molecule that is reduced gains electrons and is the oxidizing agent. C) The molecule that is oxidized gains electrons and is the reducing agent.
- Based on the name, NADH dehydrogenase isa) a vitamin that oxidizes NADH.b) a vitamin that reduces NADH.c) a vitamin that produces NADH.d) an enzyme that oxidizes NADH.e) an enzyme that reduces NADH.During the citric acid (Krebs) cycle, the energy from acetyl-CoA is captured in which molecules? CHOOSE ALL THAT APPLY. A)Hydrogen Atoms B)Pyruvate C)ATP D)Carbon Dioxide E)Reduced electron carriersWhich statement about NADH is true? It only functions in photosynthesis. It is a key electron carrier in redox reactions. It does not carry electrons. It binds with an acetyl group to form acetyl CoA. It is not involved in cellular respiration.
- Which of the following reaction pathways is primarily exergonic? (Remember that exergonic reactions do not need a continuous energy input.) Group of answer choices A. glycolysis B. P680 C. Krebs cycle D. Calvin cycle E. P700Why is the formation of ATP by ATP synthase referred to as oxidative phosphorylation? A. A phosphate is transferred from oxygen to ADP to form ATP B. Oxygen provides the mechanical energy that is used to create ATP from ADP C. Oxygen is the final electron acceptor in the electron transport chain, which creates the proton gradient necessary to power ATP synthase D. ADP combines with oxygen to form ATPConsider the reaction: Ketoglomerate + NAD --> ketocitrate + NADH In the reaction to the left, NADH is the ___________ and is in a/an ______ state compared to NAD. Select one: a. substrate, oxidized b. substrate, reduced c. product, reduced d. product, oxidized
- Which of the following reactions is the most exergonic? a Conversion of PEP to Pyruvate b Conversion of Glucose-6-phosphate to Glucose c All of the reactions are equally exergonic. d Hydrolysis of ATPIn cellular respiration, what happens as a direct result of the oxidation of NADH? A)Glucose is converted to two pyruvates B) The electron from NADH is attached to ADP to create ATP C)Acetyl-CoA enters the Calvin cycle D)Electrons enter the electron transport chain (ETC) 8.True 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
