- The oxidative phase of the pentose phosphate pathway produces which of the following (note - select all that apply)? A. ATP B. Glucose-6-phosphate C. NADPH D. Ribose-5-phosphatearrow_forwardWhich of the following dehydrogenases delivers electrons to directly to UQ in the electron transport pathway from the intermembrane space side of the inner mitochondrial membrane? a. succinate dehydrogenase b. acyl CoA dehydrogenase c. creatine kinase dehydrogenase d. glycerol-3-phosphate dehydrogenasearrow_forwardWhich of the following statements are TRUE?Multiple answers are accepted for this question a .Two molecules of CO2 are produced each time a molecule of Acetyl-CoA is oxidized. b. During the first turn of the TCA Cycle the carbon atoms of Acetyl-CoA become CO2. c. The number of molecules of ATP that can be produced in the Citric Acid Cycle by substrate level phosphorylation of ADP from two molecules of Acetyl-CoA is 30. d. Fumarate contains a trans double bond. The cis isomer of Fumarate is Maleate which cannot serve as carbon source for a cell. e. Lack of O2 would decrease the rate of the Citric Acid Cycle in red blood cells. f. If a potent inhibitor of Succinyl-CoA Synthetaseis is applied to liver cells both energy production and synthesis of carbohydrate would be affected. g. The overall chemical changes that occur during one complete turn of the Citric Acid Cycle is the complete oxidation of one molecule of Acetyl-CoA plus the production of two molecules of CO2 plus the…arrow_forward
- At the very end of cellular respiration (glycolysis followed by pyruvate oxidation, the citric acid cycle, and electron transport/ATP synthesis), a. In what molecules are all of the carbons from the glucose? b. In what molecules are many of the electrons from the glucose? c. In what molecules is much of the free energy that was harvested from the glucose?arrow_forwardIndicate whether each of the following aspects of the carnitine shuttle system associated with the process of B oxidation occurs in the mitochondrial matrix or in the mitochondrial intermembrane space. a. Acyl CoA is reactant b. Carnitine enters the inner mitochondrial membrane. c. Carnitine is covered to acyl carnitine. d. Free CoA is reactantarrow_forwarda) Explain how in oxygenated tissue your cells use your MITOCHONDRIA to produce energy: DESCRIBE the processes occurring in your MITOCHONDRIA (intermediate stage, Krebs, and ETC), Make sure to mention where those processes occur.b) How many ATP per glucose are formed in your mitochondria? Where are they formed?arrow_forward
- Which of the following statements concerning the enzyme regulation is CORRECT? Select one: A. Citrate is the allosteric inhibitor of hexokinase. B. AMP is the alloseric activator of pyruvate dehydrogenase. C. Glucose-6-phosphate is the allosteric activator for phosphofructokinase. D. ATP is the activator of pyruvate kinase.arrow_forwardConsider ten glucose molecules that enter a cell. How many ATP can be generated by the complete catabolism of these into CO2 and H2O? If all ten are first incorporated into glycogen, liberated from glycogen, and then fully catabolized into CO2 and H2O, does the ATP tally increase, decrease or stay the same? Consider that 1 UTP = 1 ATP. Explain. Describe the processes which produce ATP and provide a balanced equation of glucose, CO2, H2O and O2arrow_forwardIf your body sense that is very low on the substrates necessary to produce ATP homeostatic control mechanisms will alter enzyme levels such that your body begins the processes of deamination and gluconeogenesis. Combined, these two sets of chemical pathways convert amino acids and already assembled proteins into substrates for glycolysis and the citric acid cycle, thereby replenishing (in part) your supply of energy. This is an example of what? a. positive feedback loop b. negative feedback loop c.feedforward regulationarrow_forward

A voltage that reflects the movement of protons across the inner mitochondrial membrane d.) A voltage that reflects the movement of ATP across the inner mitochondrial membranearrow_forwardMark each as true or false with brief explanation to whyarrow_forwardConsider a 24:1 △cis-9 fatty acid in the mitochondrion.
