Arsenate (AsO³-) closely resembles phosphate in structure and reactivity. However, arsenate esters are unstable and arespontaneously hydrolyzed.If arsenate is added to actively respiring mitochondria, what would be the effect on ATP synthesis?ATP synthesis will decrease because cells require less energy when arsenate is available.ATP synthesis will not be affected because mitochondria are incapable of taking up arsenate.ATP synthesis will stop due to the formation arsenate-ADP anhydrides.ATP synthesis will increase because arsenate anhydride hydrolysis increases ATP turnover.If arsenate is added to actively respiring mitochondria, what would be the most likely effect on the rate of theelectron-transport chain?The rate of electron transport will decrease, because arsenate inhibits Complexes I and II.The rate of electron transport will decrease, because arsenate inhibits the citric acid cycle.The rate of electron transport will increase, because arsenate increases the demand for ATP.The rate of electron transport will increase, because arsenate is uncoupling respiration.

Arsenate mimics the structure of phosphate. Because of this, arsenate binds to the phosphate binding…

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?

TPI deficiency is a rare human condition. Patients who lack TPI cannot convert the triose dihydroxyacetone phosphate into glyceraldehyde 3-phosphate.What happens to glycolysis in TPI patients?TPI patients suffer from chronic hemolytic anemia (abnormal breakdown of red blood cells) and have variable neuromuscular dysfunctions, including muscle weakness, poor muscle tone, and atrophy. Most die of respiratory failure during childhood. Explain why TPI-deficient patients exhibit these conditions using the diagram to justify your answer. TPI is enzyme 5.G6PD deficiency is one of the most common human genetic conditions, affecting about 40 million people worldwide. Patients suffer from hemolytic anemia when exposed to certain drugs, viral or bacterial disease, or fava beans.
What terms would best describe the above coupled reaction? (If the DGo for ATP hydrolysis into ADP + inorganic phosphate is -7.3 kcal/mole, and the DGo for maltose synthesis from glucose + glucose is +3.7 kcal/mole, calculate the standard free energy change for the combined reaction of ATP + glucose + glucose g ADP + maltose + inorganic phosphate.) it is non-spontaneous and endothermic (because the overall DGo is negative) it is spontaneous and exothermic (because the overall DGo is negative) it is non-spontaneous and endothermic (because the overall DGo is positive) it is spontaneous and exothermic (because the overall DGo is positive) it is non-spontaneous and exothermic (because the overall DGo is negative)
In a major metabolic pathway involving the monosaccharide glucose, one of the reactions involve the conversion of glucose to glucose-6-phosphate summarized below together with accompanying free energy change: glucose + phosphate = glucose-6-phosphate + H,0 AG = 13.8 kJ · mol-1 (Reaction 1) In cells, the production of G6P (Reaction 1 above) is coupled to a reaction that involves the hydrolysis of ATP to ADP (shown below, Reaction 2) which makes the overall reaction much more favorable to the production of glucose-6-phosphate. ATP + H,O = ADP + phosphate (Reaction 2) Why do you think coupling the production of glucose-6-phosphate to the hydrolysis of ATP makes the overall reaction spontaneous? What can you say about the free energy change accompanying the hydrolysis of ATP (Reaction 2)?
