- Match the term with the best description. _____ mitochondrial matrix a. needed for glycolysis _____ pyruvate b. inner space _____ NAD+ c. makes many ATP _____ mitochondrion d. product of glycolysis _____ NADH e. reduced coenzyme _____ anaerobic f. no oxygen requiredWhich of the following statements is most correct? The electron transport chain - A: generates a pH gradient that reduces O2 to H2O B: generates a proton gradient across the outer mito membrane C: generates a proton gradient across the inner mito membrane D: uses the energy stored in high energy electron carriers to synthesize ATP E: establishes a membrane potential across the outer mito membraneThere are some drugs that can inhibit the activity of ATP synthase. How does this affect the pH of the inner membrane space and the mitochondrial matrix?
- In the cellular respiration process located where CO2 is given off, NAD and FAD pick up H’s and ATP is recharged and how many are involved in each location?Why are electron carriers (NAD+/NADH and FAD/FADH2) so important in the process of cellular respiration? A)NADH and FADH2 are major components of the ETC, so without them, there would be no ETC in the cell. B)They deliver electrons to the ETC, which in turn sets up chemiosmosis, where most of the ATP is generated. C)They separate the electrons from the protons so that the protons can be moved out of the mitochondrion. 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. 14.Does the electron transport chain produce ATP?(directly) If yes, draw the steps that directly produce ATP. If no, draw the process that directly produces ATP and explain how it relates to the electron transport chain.
