Isolated mitochondria are able to sustain ATP synthesis when provided with ADP, Pi, O2, and a regenerating supply of NADH or FADH2 as the sole source of electrons for oxidative phosphorylation. Predict how inhibition of Complex I will affect O2 consumption and ATP synthesis. Answer choices: Decrease Increase No change Site of inhibition Sole source of electrons Oxygen consumption ATP synthesis Complex I NADH Complex I FADH2

Given the definition of a monosaccharide as an aldehyde or ketone having two or more hydroxyl groups, identify the monosaccharide among the glycolytic intermediates below.  glycolytic 3-carbon intermediates.png

Given that all phosphotransferases have similar catalytic mechanisms, consider the half-reactions for the uncatalyzed transfer of inorganic phosphate from 1,3-BPG to ADP. One half-reaction produces water and the other consumes water. Observe that the phosphoglycerate kinase (PGK)-catalyzed phosphoryl transfer from 1,3-BPG to ADP does not include water. Select the best explanation for why the catalyzed reaction does not include water. uncatalyzed half-reaction 1 1,3-BPG + H2O → 3BPG + Pi uncatalyzed half-reaction 2 ADP + Pi → ATP + H2O PGK-catalyzed coupled reaction 1,3-BPG + ADP → 3PG + ATP

The exergonic flow of electrons from NADH catalyzed by Complex I is sufficient to drive which of the following endergonic processes? 

Given the Bx resource and the reductants below, identify the one that will most readily give up its electrons.

Given the Gibbs free energy equation in the Bx resource, the reaction catalyzed by phosphoglycerate kinase, its ΔGo’, and its ΔG under typical physiological conditions, 1 , 3 – B P G + A D P ⇄ 3 P G + A T P Δ G 0 ‘ = 18 . 8   k J · m o l – 1 Δ G = 1 . 3   k J · m o l – 1 identify each statement as True or False.   The reaction is near equilibrium under physiological conditions.   ΔG is the determining factor for whether the reaction is near or far from equilibrium.   Elevating the concentration of ATP will accelerate the forward reaction.   At equilibrium, the product of the concentrations of 3PG and ATP will equal the product of the concentrations of 1,3BPG and ADP.

Malate dehydrogenase catalyzes the following reaction in the citric acid cycle (ΔGo’= +29.7 kJ mol-1).malate + NAD+ → oxaloacetate + NADHMatch each half reaction with its correct thermodynamic nature of the reaction.
