You treat cells with 2,4 dinitrophenol (DNP). This compound creates a temporary channel in the inner membrane of the mitochondria though the protons can move. Which of the following would you observe in these cells? Select all that apply The cells do not synthesize ATP in the presence of DNP The cells synthesize ATP in the presence of DNP The cells reduce oxygen in the presence of DNP The cells generate carbon dioxide in the presence of DNP

Loss of this enzyme would be lethal to the cell CH₂-CH-CH₂ OH OH Glycerol- phosphate Loss of this enzyme would severely reduce the exchange of lipids between the cytosol and lumen P CH₂-CH-CH₂ O O I =C C=O Loss of this enzyme would lead to membrane phospholipids with identical phosphate head groups Phosphatase Acyl transferase Loss of this enzyme would result in membranes deficient in phosphatidylcholine Choline head Cytosol group ER lumen Choline phosphotransferase Loss of these enzymes would prevent lipid transfer between the ER and mitochondria Flippase lipid exchange proteins
All of the following compounds have sufficiently high group transfer potentials to lead to the production of ATP except: 1,3-bisphosphoglycerate. acetyl-CoA. O phosphocreatine. glucose-6-phosphate. phosphoenolpyruvate.
Can you explain why when the pH level was changed from 0 to 5, the ATP production was affected despite the supply of glucose being constant at just 1 mol for both treatments (At 0 pH and 5 pH). What is the reason on why this could have happened?
Explain in complete manner why these 3 became the major pathway that eventually become the entry points for molecules into the Citric Acid Cycle: Glycolysis Oxidation of fatty acid Protein catabolism
Which steps are part of the energy investing half of glycolysis? OPhosphorylation Isomerization Second Phosphorylation Cleavage Conversion of DHAP into GADP O Dephosphorylation Phosphate transfer O Dehydration Second dehydration
All of the following statements about the citric acid cycle are true except: O The citric acid cycle occurs in the cytoplasm of prokaryotes. O The citric acid cycle regenerates NAD+ and FAD. O The citric acid cycle involves one or more redox reactions. O The citric acid cycle is part of cellular respiration.
Like many fruits, apples contain not only fructose and glucose, but also sucrose, a dimerof fructose and glucose. Synthesizing sucrose is endergonic and so not spontaneous. Onerole of ATP is to facilitate reactions that would not occur spontaneously. The threephosphate groups are electron rich and tend to repel each other. Therefore, ATP is a bitlike a compressed spring, ready to kick off one phosphate group releasing energy.Consider: Fructose + glucose --> Sucrose delta G= 6.4 kcal/mol ATP --> ADP + Pi delta G= -7.3 kcal/mol a. Draw a simple energy diagram (including the relative energy of the reactants andproducts) that shows why the sucrose synthesis reaction doesn’t occur spontaneously. b. How could having these two reactions occur at the same time help with sucroseproduction? c. Draw the energy diagram that shows all the reactants and products for the combinedreactions. d. What is delta G for the combined reactions? e. Name a few of the biological processes in the body that…
ADP and inorganic phosphate are provided for oxidative phosphorylation via an: ADP-ATP antiport and a proton-phosphate symport in the inner mitochondrial membrane. ADP-ATP antiport and a proton-phosphate symport in the outer mitochondrial membrane. O ADP-ATP antiport in the inner mitochondrial membrane and a phosphate uniport in the mitochondrial intermembrane space. ADP-phosphate symport in the inner mitochondrial membrane.
Transporting anything through the mitochondrial membrane can be difficult. How do cells get Oxaloacetate in and out?
