- The first step of the metabolic process known as glycolysis is the conversion of glucose to glucose- 6-phosphate. This process has a positive value for rG' Glucose + Pi Glucose-6-phosphate + H2O rG' = +13.8 kJ/mol-rxn This reaction is coupled to the hydrolysis of ATP ATP + H2O ADP + Pi rG' = -30.5 kJ/mol-rxn What is the sum of these two equations and the value of rG' for the coupled reaction? Is the coupled reaction product-favored at equilibrium?arrow_forwardWhy are so many different enzymes needed?arrow_forwardList, by name, the four general stages of the process by which biochemical energy is obtained from food.arrow_forward
- What is the most biochemical reactions inside our body need to speed up?arrow_forwardWhich of the following are thought to be possible explanations for apparent contradictions in the energy balance as it relates to weight loss and the thermodynamic laws? O self reported energy intake and expenditures. O the assumption that weight loss is based on carbohydrates decreases only. O metabolic efficency D over time as weight loss occurs there will be increases in resting energy expenditure.arrow_forwardWhat is metabolism and where is energy produced in cells?arrow_forward
- 1a) Under aerobic conditions, what is the net production of ATP under glycolysis? a. 2 ATP b. 4 ATP c. 36 ATP d. None of the above 1b). What reaction occurs when NAD+ is converted to NADH + H+? a. Hydrolysis b. Oxidation c. Reduction d. Phosphorylatioarrow_forwardThe AGo' of a reaction is -250 kcal/mol. Which of the following can be deduced about this reaction? At equilibrium, [products] > [reactants]. Keq < 1 The reaction will proceed spontaneously under cellular conditions. None of the above can be deducedarrow_forwardGlycolysis, A. is the breakdown of glucose to two pyruvic acid molecules. B. requires the input of two ATP molecules. C. produces two NADH molecules. D. does not require oxygen. E. all of the above.arrow_forward
- The carbon dioxide you breathe out comes from A. glycolysis. B. the electron-transport chain. C. anaerobic respiration. D. the food you eat.arrow_forwardFor what is the energy released during metabolism in humans used?arrow_forward1- Find the amount of energy released (in kcal) by: • 1 gram of proteins • 1 gram of carbohydrates • 1 gram of fatsarrow_forward
