When fats are used as an energy source, the glycerol portion enters _____ after it has been converted to _______. - The citric acid cycle ; pyruvate  - The electron transport system ; coenzyme Q  - The citric acid cycle ; acetyle oA - Glycolysis ; fructose-6-phosphate - Glycolysis ; dihydroxyacetone phosphate

Each NADH and FADH2 molecule formed represents ______ energy… contain high energy electrons from food molecules (glucose_ which are carried to an electron transport chain.

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…

All are steps of aerobic cellular respiration EXCEPT for (you can select more than one answer):   glycolysis   Krebs cycle   electron transport chain   fermentation

The first energy production pathway in glycolysis involves the conversion of ______ to ______.   Glycerhaldehyde-3-phosphate; 1,3-bisphosphoglycerate   Fructose-6-phosphate; Fructose-1,6-bisphosphate   1,3-bisphosphoglycerate; 3-phosphoglycerate   Phosphoenolpyruvate; pyruvate

The final net products of glycolysis are ________.     4 molecules of ATP and 2 NADH 4 molecules of ATP and 2 NADH 2 molecules of ATP and 2 NADH 2 molecules of ATP and 2 NADH 2 molecules of ATP and 4 NADH 2 molecules of ATP and 4 NADH

Which of the following releases 4 CO2 per glucose? O glycolysis O pyruvate oxidation citric acid cycle O chemiosmosis O electron transport chain
