The Relative Efficiency of ATP Synthesis in Noncyclic versus Cyclic Photophosphorylation If noncyclic photosynthetic electron transport leads to the translocation of 7 H+/2e- and cyclic photosynthetic electron transport leads to the translocation of 2 H+/e-, what is the relative photosynthetic efficiency of ATP synthesis (expressed as the number of photons absorbed per ATP synthesized) for noncyclic versus cyclic photophosphorylation? (Assume that the CF1CF0-ATP synthase yields 3 ATP/14 H+.)
Concerning the process of the aerobic fate of glucose oxidation, which of the following statements is false? a. The spontaneous movement of protons is coupled to the unfavorable movement of electrons through the electron transport chain b. Pyruvate is recognized by a pyruvate/proton symporter for movement into the matrix of the mitochondria c. The matrix of the mitochondria is more negative than the inner membrane space d. Mitochondria contain two membranes, only the inner mitochondrial membrane is highly selective for what passes across it e. The movement of protons through ATP synthase drive the production of ATP
The binding of ATP with the enzyme pyruvate kinase result's in this enzyme's failure to catalyze the last step in the breakdown of glucose during the process of glycolysis. In this situation, ATP acts as the ________ of pyruvate kinase.
(a) Hexokinase (HK), phoshofructokinase (PFK) and pyruvate kinase are three regulatory enzymes that regulate metabolic reaction in glycolysis. Elaborate how equilibrium conditions would be controlled by these enzymes. PLEASE FAST AND RIGHT CLEER.
In order for an adipose cell to synthesize decanoic acid, it will need substrates in the form of _______ ATP, _______ NADPH from the transport of citrate into the cytoplasm and the subsequent recycling of oxaloacetate, and _______ NADPH from the pentose phosphate pathway. You can ignore the ATP used to regenerate mitochondria oxaloacetate via pyruvate carboxylase.
In terms of aerobic cellular respiration, explain how the irreversible steps of glycolysis and krebs, work in concert with oxidative phosphorylation (i.e., ETC and ATP synthase) to regulate the energy charge of the cell? Why do hepatocytes make more ATP from glucose than myocytes?
Assuming that the glycerol 3-phosphate shuttle is operative, a complete oxidation of five molecules of glucose (by a eukaryotic cell) into carbon dioxide and water would produce approximately _________ ATP molecules via oxidative phosphorylation only. (Consider NADH = 2.5 ATP and FADH2 = 1.5 ATP)
The citric acid cycle is frequently described as the major pathway of aerobic catabolism, which means that it is an oxygen-dependent degradative process. However, none of the reactions of the cycle directly involve oxygen as a reactant. Why is the pathway oxygen dependent?
The proton-motive force drives the rotation of the Y subunit of ATP synthase. This creates conformational changes in the active sites of ATP synthase that accelerate the rate of bond formation between ADP and P, through the stabilization of a tetrahedral intermediate. True False
Liver cells need NADH and ATP for gluconeogenesis, which involves both cytoplasm and mitochondria. From cytoplasm, pyruvate enters the mitochondria via transporter protein and in mitochondria, pyruvate undergoes carboxylation and reduction. The reduction produces _______, which is transported from mitochondria to cytoplasm via its transporter protein.
