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 cycle. E Electrons are passed from one carrier to another, releasing a little energy at each step.

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 captured from electrons flowing to oxygen to produce most of the ATPs in cellular respiration.

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 energy required to pump from the mitochondrial matrix to the intermembrane space of the mitochondria d. Without oxygen, the ETC is able to produce substantially greater amounts of ATP via aerobic metabolism.

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 synthase generates a H+ gradient across the inner mitochondrial membrane. The electron transport chain of proteins uses ATP to pump H+ across the inner mitochondria membrane against its electrochemical gradient
