4) a)Fill in the blanks: When oxygen is the final energy carrier in the production of ATP, the process is called _________________. When an inorganic molecule is used to drive theoxidation in a cell to produce ATP, the process is called _______________.b)How is energy transferred to proteins in the process called phosphorylation?c) Fill in the blanks: When a molecule is oxidized it has (more/less) _________ electrons than it did before being oxidized. When a molecule is reducedit has (more/less)_________ electrons than it did before being reduced.d) Is NADH is the oxidized or reduced form of NAD+?
9 .The energy of electron transport (by the ETC) serves to move protons (hydrogen ions, or H+) to the intermembrane space of the mitochondrion. How does this help the mitochondrion produce ATP? a) This movement of protons sets up the electrochemical gradient that drives ATP synthesis in the mitochondrion. b) The protons pick up electrons from the electron transport chain on their way through the inner mitochondrial membrane c) The protons receive electrons from the NAD+ and FAD that were accepted in glycolysis ad the citric acid cycle d) The protons are transferred to oxygen in an energy-releasing reaction
7. Why are electron carriers (NAD+/NADH and FAD/FADH2) so important in the process of cellular respiration? a) They deliver electrons to the ETC, which in turn sets up chemiosmosis, where most of the ATP is generated. b) They separate the electrons from the protons so that the protons can be moved out of the mitochondrion. c) NADH and FADH2 are major components of the ETC, so without them, there would be no ETC in the cell. d) The electrons that they carry are able to directly phosphorylate ADP in order to generate the bulk of ATP in the cell. e) They transport protons across the mitochondrial membrane.
The proton motive force is the result ofa. ATP synthase transporting protons during ATP synthesisb. an electron gradient between the matrix and the intermembranespace of a mitochondrionc. a proton gradient between the matrix and intermembrane space ofa mitochondriond. a buildup of negatively charged ions
