Concept explainers
(a)
Interpretation:
Whether the “production of citrate from oxaloacetate and acetyl CoA” in citrate-malate shuttle system occur in the mitochondrial matrix or in the cytosol has to be determined.
Concept introduction:
Lipogenesis is the process employed for the synthesis of fatty acid. The starting precursor for the synthesis is acetyl CoA. The enzyme employed for the process is fatty acid synthase. It is a multienzyme complex that ties the reaction responsible for the synthesis of fatty acid.
Acetyl CoA is synthesized in mitochondria and then transported to cytosol through the citrate-malate shuttle system.
(b)
Interpretation:
Whether “ATP conversion to ADP” occurs in the mitochondrial matrix or in the cytosol in the citrate–malate shuttle system has to be determined.
Concept introduction:
Lipogenesis is the process employed for the synthesis of fatty acid. The starting precursor for the synthesis is acetyl CoA. The enzyme employed for the process is fatty acid synthase. It is a multienzyme complex that ties the reaction responsible for the synthesis of fatty acid.
Acetyl CoA is synthesized in mitochondria and then transported to cytosol through the citrate-malate shuttle system.
(c)

(d)
Interpretation:
Whether “NADH is used as a reducing agent” in the mitochondrial matrix or in the cytosol in the citrate–malate shuttle system has to be determined.

- Why does a deficiency of carbohydrates in the diet lead to ketone body formation?arrow_forwardWhich nutrient provides energy in its most concentrated form?arrow_forwardFatty acids and triglycerides are an important source of nutrition and a dense form of stored energy. Digestion of fats yields more energy per gram than digestion of carbohydrates. Each turn on the B-oxidation spiral results in the formation of a new acetyl COA molecule. This molecule can then be used to generate more energy in A) fatty acid synthesis B) ketolysis C) glycolysis D) tricarboxylic acid cycle E) oxidative phosphorylationarrow_forward
- Which of these reactions take place in both anaerobic and aerobic respiration? A. glycolysis B. citric acid cycle C. electron-transport chain D. acetyl-CoA formation E. all of the abovearrow_forwardIn the electron transport chain, the hydrogen ions enter the inner compartment of mitochondria through special channels formed by A. ATP synthase. B. coenzyme A. C. acetyl CoA. D. oxygen.arrow_forwardRigor mortis, the stiffening of muscles. after death is due to the depletion of intracellular ATP. Provide the biochemical basis of rigor mortisarrow_forward
- How many electron carrier molecules (both NADH and FADH₂) are made per glucose put in to glycolysis? How many electron carrier molecules (both NADH and FADH₂) are made per pyruvate put in to the Krebs Cycle? How many electron carrier molecules (both NADH and FADH₂) are made by the Krebs Cycle per glucose consumed by the organism? How many electron carrier molecules in total (both NADH and FADH₂) have been made from a single glucose after both glycolysis and the Krebs Cycle? How many electrons are being carried from glucose at this point (Hint: 2 per molecule)?arrow_forwardWhat is the process that produces glucose intended for use in brain cells and red blood cells in starved state? Glycolysis Glycogenolysis Glycogenesis Gluconeogenesisarrow_forwardWhat is the key chemical reaction that is found in the first stage of metabolism?arrow_forward
- What is the name of the enzyme that converts glycerol to glycerol-3-phosphate?arrow_forwardQUESTION 41 In the deficiency referred to in question 40, a deficiency of the form of develops which makes the erythrocyte susceptible to oxidative destruction oxidized, oxaloacetate O oxidized, glutathione reduced, oxaloacetate reduced, glutathionearrow_forwardIn which direction do protons move through ATP synthase? a. from the intermembrane space to the matrix of a mitochondrion b. from the matrix to the intermembrane space of a mitochondrion c. from the inner membrane to the outer membrane of a mitochondrion d. from the outer membrane to the inner membrane of a mitochondrionarrow_forward
