please help!! 37. What is the name of the enzyme that creates ATP in oxidative phosphorylation?...
Which two processes make up oxidative phosphorylation? A. Chemiosmosis and ATP synthesis B. Electron transport chain and chemiosmosis C. Pyruvate oxidation and electron transport chain D. Proton motive force and chemiosmosis What is the final electron acceptor in the electron transport chain? A. FADH2 B. Water C. Oxygen D. NADH
Fill in the blanks regarding the electron transport chain and oxidative phosphorylation. Complex1 accepts electrons from NADH and uses coenzyme Q to transport them to complex 3. Complex 2 accepts electrons from FADH2 and uses coenzyme q to transport them from complex 3 to complex 4. The ATP synthase will transport 3H+ ions for every 2 ATP produces. This entire process occurs across the inner mitochondrial membrane. Fill in the blanks regarding the electron transport chain and oxidative phosphorylation
Which of the following could explain why transfer of electrons from FADH2 to Coenzyme Q (CoQ) is not coupled to proton transfer, but transfer from NADH to Coenzyme Q is? Select one: a. FADH2 donates more electrons than NADH to the electron transport chain. b. Because FADH2 has higher affinity for electrons than Coenzyme Q c. Because FADH2 is a higher energy carrier than NADH d. Because the transfer of electrons from FADH2 to CoQ does not release enough energy....
C. Considering Electron Transport: In LA3 Video 3, we are considering electron transport and oxidative phosphorylation. Please answer the following multiple choice questions (0.5 pts each) and follow instructions for two final drawings (2 pts each). 1. The electrons involved in electron transport come from (A) glycolysis (B) the pyruvate dehydrogenase complex (C) the citric acid cycle (D) all three processes 2. When NADH and FADH2 transfer their electrons to the electron transport chain, they are (A) oxidized (B) epimerized...
1. Select the TRUE statement about the citric acid cycle. A. Isocitrate dehydrogenase is a multienzyme complex that is very similar to the pyruvate dehydrogenase complex B. The two decarboxylation steps occur right after each other, first via oxidative alpha- decarboxylation, then via oxidative beta- decarboxylation. C. In one turn of the cycle, the two carbons that enter the cycle as acetyl CoA are the same two carbons that are released as CO2. D. A flavin containing dehydrogenase enzymes oxidizes...
1. Select the TRUE statement about the component of the electron transport chain. A. Complex III is a peripheral membrane protein B. Cytochrome c is a lipid-linked protein C. Complex II is a transmembrane protein D. Complex I is an integral membrane protein E. Complex IV is not a transmembrane protein 2. The rate of oxygen consumption at the inner mitochondrial membrane is related to all the following EXCEPT: A. Availability of ADP in the mitochondria B. The rate of...
QUESTION 2 What is the main mechanism of action for oxidative phosphorylation? A Uses the free energy of the proton gradient generated as a result of transferring electrons from NADH OF FADH2 to O2 by a series of electron carriers for ATP production B. Uses the net yield of ATP produced by Glycolysis and the Citric Acid Cycle to produce more ATP. Uses the free energy released during redox reactions in Complexes I-IV (the electron transport chain) and is uncoupled...
