Which of the following best describes the electron transport chain? A Electrons are pumped across a membrane by active transport. B Acetyl CoA is fully oxidized to CO2. C Hydrogen atoms are added to CO2 to make an energy-rich compound. D Glucose is broken down to a three-carbon compound in preparation for the citric acid … Read more

Which statement describes the electron transport chain? This process joins 2 pyruvic acid molecules into a molecule of glucose. This process converts pyruvic acid to acetyl CoA. This process splits glucose in half and produces 2 ATPs for each glucose. This process produces some ATP and carbon dioxide in the mitochondrion. This process uses energy … Read more

Which of the following is not true of the Electron Transport Chain? a. movement through ATPase provides the energy required to resynthesize ATP from ADP and phosphate. b. is pumped into the intermembrane space of mitochondria via a series of four cytochrome complexes c. NADH and donate electrons to the ETC. These electrons provide the … Read more

Which of the following statements concerning the electron transport chain is false? a. The final electron acceptor is oxygen. b. Each NADH yields three ATP molecules. c. Each FADH2 yields two ATP molecules. d. The electron transport chain will work whether oxygen is present or not.

Which of the following statements about the electron transport chain in cell respiration is CORRECT? The electron transport chain of proteins contains pores that are leaky to H. The loss in free energy of the electron initially donated by NADH is used to transport H+ across the inner mitochondrial membrane against its electro The ATP … Read more

State whether the following statements are true or false. The carrier molecules of the electron transport system are located in the cytosol. True False

Which of the following statements about the electron transport chain is true? Group of answer choices A) It is driven by ATP hydrolysis. B) It includes a series of hydrolysis reactions associated with mitochondrial membranes. C) It consists of a series of redox reactions D) It occurs in the cytoplasm of both prokaryotic and eukaryotic … Read more
