glycogenesis.glycogenolysis.gluconeogenesis. - 6. Multiple ChoiceWhich of the following is the correct order of the body’s energy fuel preference, starting with the first choice and ending with the third choice?
Carbohydrates, fats, proteinsCarbohydrates, proteins, fatsFats, carbohydrates, proteinsProteins, carbohydrates, fats - 7. Multiple ChoiceFat or lipids are mostly stored in what form?proteincarbohydratestriglyceridesglucose
- 8. Multiple ChoiceWhen the blood glucose level starts to decrease toward lower than normal:liver cells increase the rate at which they convert glycogen, amino acids, and fats to glucose.there is an increase in glycogenolysis.there is an increase in gluconeogenesis.all of the above occur.
- 9. Multiple ChoiceGlucose must be broken down by the process known as ___ in order to processed by the mitochondria.glucogenesisglycongenolysisglycolysisglycogenesis
- 10. Multiple ChoiceGlycolysis always requires oxygen.TrueFalse
- 11. Multiple ChoiceAerobic metabolism means that oxygen is involved in the process.TrueFalse
- 12. Multiple ChoiceAerobic metabolism takes place in what cell organelle?mitochondriaGolgi apparatusnucleuscytoplasm
- 13. Multiple ChoiceThe process of glycolysis takes __ carbon glucose and breaks it down to __ carbon pyruvic acid.3,62,46,34,3
- 14. Multiple ChoiceThe conversion of proteins to glucose is an example of:
glycogenesis.gluconeogenesis.glycogenolysis.glycolysis. - 15. Multiple ChoiceThe process by which proteins are synthesized by the ribosomes in all cells is called protein:catabolism.anabolism.metabolism.transcription.
- 16. Multiple ChoiceEnergy in our bodies comes in the form ofADPATPpyruvic acidphosphate
- 17. Multiple ChoiceWhat process has pyruvic acid and two gained ATPs as end products?Krebs cycleGlycolysisAnaerobic pathwayElectron transport chain
- 18. Multiple ChoiceWhich process produces lactic acid? (The Cori cycle helps repay the oxygen debt incurred by this process.)Krebs cycleGlycolysisElectron transport chainAnaerobic metabolism
- 19. Multiple ChoiceThe waste product produced from the citric cycle iscarbon dioxide (CO2)pyruvic acidADPacetyl-CoA
- 20. Multiple ChoiceWhat is the percentage of ATP created in the mitochondria?25%55%70%90%
- 21. Multiple ChoiceWhich process begins with acetyl CoA and produces high-energy electrons and hydrogen carrier molecules?Krebs cycleAnaerobic pathwayGlycolysisElectron transport chain
- 22. Multiple ChoiceWhich statement best compares the processes of anabolism and catabolism?Both catabolism and anabolism take place outside of the cells in the GI tract.Catabolism breaks food molecules down into smaller molecular compounds and, in so doing, releases energy from them. Anabolism does the opposite.Anabolism breaks food molecules down into smaller molecular compounds and, in so doing, releases energy from them. Catabolism does the opposite.Anabolism occurs when nutrient molecules enter cells, undergo many chemical changes, and release ATP for energy; catabolism doesn’t release ATP.
- 23. Multiple ChoiceThe sum of all of the biochemical processes going on within the human body at any given time is calledglycolysis.oxidative phosphorylation.metabolism.catabolism
- 24. Multiple ChoiceThe electron transport systemreceives electrons from coenzymes.produces energy that supports the synthesis of ATP.is found on the inner mitochondrial membrane (the cristae)all of the above
- 25. Multiple ChoiceReactions within ________ provide most of the energy needed by a typical cell.cytoplasmthe plasma membranethe mitochondriathe endoplasmic reticulum
- 26. Multiple ChoiceThe function of the citric acid cycle is toremove hydrogen atoms from organic molecules and transfer them to coenzymestransfer the acetyl group.hydrolyze glucose.produce carbon dioxide.
- 27. Multiple ChoiceCells perform catabolism to generate ATP, which can be used formuscle contraction.protein synthesis.glycogen synthesis.all of the above
- 28. Multiple ChoiceCatabolism of all of the following is fairly common for energy production, except A) B) C) D)carbohydrates.lipids.glucose.protein.
