- Put the following pathways in the order they occur during aerobic respiration. a. electron transfer phosphorylation b. acetylCoA formation c. citric acid cycle d. glycolysisThe aerobic part of aerobic cellular respiration occurs during (a) glycolysis (b) the conversion of pyruvate to acetyl CoA (c) the citric acid cycle (d) electron transport (e) all the preceding are aerobic processesIf glycolysis has an overall –DG (i.e., it’s exergonic), why does it require an energy investment of two ATP to happen?
- A 70-kg adult human (154 lb) could meet his orher entire energy needs for one day by eating 3 moles ofglucose (540 g). (We do not recommend this.) Each mol-ecule of glucose generates 30 molecules of ATP when it isoxidized to CO2. The concentration of ATP is maintained incells at about 2 mM, and a 70-kg adult has about 25 litersof intracellular fluid. Given that the ATP concentrationremains constant in cells, calculate how many times perday, on average, each ATP molecule in the body is hydro-lyzed and resynthesized.dtermoine numberof ATPS GENERATED FROM COMPLETE oxidation of fructose-6-phosphate isocitrate stearidonic acid [18 carbons triangle 6,9,12,15] indicate where everything comes from ex ATPS FROM GLYCOLYSIS , NADH FROM TCA ETC LIST ALLThe energy stored in the carbon-carbon bonds of glucose is anexample of _____ energy.a. kineticb. potentialc. chemicald. mechanicale.

(The other 60% is lostas heat and in waste products.) Before being used by the cells, effectively allof this energy is stored in ATP, which is then cleaved into ADP and PO3−2 , with the release of 12.5 kcal per mole of ATP.(a) How many moles of ATP are turned over per day in this fashion? Whatmass of ATP does this correspond to? (The molecular weight of ATP is507 g/mol.)(b) The body actually contains approximately 5 g ATP. Estimate the averagerecycle time for an ATP molecule. You see that it is much more efficientto reuse ADP rather than to synthesize it de novo (from scratch).
