Maria has drawn a flow chart using stars to track electron carriers (NADH and FADH₂) during cellular respiration, but she hasn't completed her model. If twelve electron carriers are delivered to the electron transport chain (ETC) per molecule of glucose, how many stars should she show being produced during glycolysis and pyruvate processing? Glucose 0 stars + 4 stars 2 stars + 2 stars 4 stars+ 0 stars no more stars Pyruvate Acetyl CoA) ETC

An animal cell, roughly cubical in shape with side length of 10 μm, uses 109 ATP molecules every minute. assume that the cell replaces this ATP by the oxidation of glucose according to the overall reaction 6O2 + C6H12O6 →6CO2 + 6H2O and that complete oxidation of each glucose molecule produces 30 ATP molecules. how much oxygen does the cell consume every minute? How long will it take before the cell has used up an amount of oxygen gas equal to its own volume?
Firefly luciferase is the enzyme that allows fireflies to illuminate their abdomens. Because this light generation is an ATP-requiring reaction, firefly luciferase can be used to test for the presence of ATP. In this way, luciferase can test for the presence of life. The coupled reactions are luciferin+O2 ⇌ oxyluciferin+light ATP ⇌ AMP+PPi, ΔGo=−31.6 kJ/mol If the overall ΔGo of the coupled reaction is -8.70 kJ/mol, what is the equilibrium constant, K, of the first reaction at 27oC?
Draw and label a lipid bilayer containing the large mitochondrial trans-membrane protein complexes representing complex I, II, III, and IV, and ATP Synthase. Label your diagrams with the correct names for the membranes, Make two more of these drawings. Label the first one mitochondrial electron source and using a different ink color, indicate the source(s) of electrons. Label the second mitochondrial energy source, and indicate the source of energy driving the electron transport chain. In the third, label the mitochondrial electron acceptor in its proper position. Also include ATP synthase (in its correct orientation-the spherical part is on the opposite side of the membrane as the H+ reservoir). Use a different color of ink to show where the protons (H+) are pumped to drive ATP synthesis. also indicate where ATP is generated and were the power is stored to generate ATP.

SEQUENCE THE FOLLOWING MAJOR EVENTS IN CELLULAR RESPIRATION USING NUMBERS 1 - 4 - A series of reactions wherein the pyruvic acid is converted from one compound to another releasing CO2, NADH, FADH2, and 2 ATP molecules. - The breakdown of one glucose molecule into two molecules of pyruvic acids; 2 ATP molecules are produced and NADH is released to be used in the later stage of cellular respiration. - In this stage, the NADH and FADH2 produced in the previous reactions give up high-energy electrons that are passed from one molecule to another, producing ATP in the process. It is in this stage that most ATP molecules are produced. - Each molecule of pyruvic acid produces one molecule each of CO2 and acetyl CoA and more NADH is produced.
Figure 7.11 Dinitrophenol (DNP) is an "uncoupler" that makes the inner mitochondrial membrane "leaky" to protons. It was used until 1938 as a weight- loss drug. What effect would you expect DNP to have on the change in pH across the inner mitochondrial membrane? Why do you think this might be an effective weight-loss drug?
