what is the transmembrane protein responsible for ATP synthesis during both photosynthesis and cellular respiration? a. Na+/K+ ATPase b. SGLUT-1 c. ATP synthase d. carbonic anhydrase e. rubisco

what will happen if the Na+ and K+ pumps are blocked?  a. intracellular Na+ will build up and sugars and amino acids will not be transported into the cell b.extracellular Na+ will build up and fats wont be co-transported into his cells  c. intracellular Na+ will build up and fats wont be transported into the cell

Which of the following would yield the most ATP? Select one: a. fermentation to produce alcohol b. fermentation in skeletal muscle c. aerobic respiration of glucose d. anaerobic respiration of glucose O

In order to improve their recovery after an intense work out or competition, many high-level athletes use "cool downs" to rapidly slow down their movements, by eating a snack, and breathing deeply. What choice below accurately explains how these steps aid cellular respiration? A. Eating a snack takes in more energy which converts to sugar needed by the body to produce oxygen to begin cellular respiration. B. Cooling down in this way they are able to take in oxygen and sugar, which allows their cells to produce energy through cellular respiration. C. Breathing deeply and eating a snack releases more carbon dioxide and sugar, which leads to more energy for cellular respiration to begin. D. Cooling down in this way they are able to take in carbon dioxide and water which allows their cells to produce energy through cellular respiration. 5.

Which process in the respiration pathway produces pyruvate, ATP, and NADH? Incorrect Answer: C. Citric acid cycle Correct Answer: A. Glycolysis. Rationale:

Palmitate is a 16-carbon fatty acid. After complete ß-oxidation of one molecule of palmitate, how many molecules of NADH are formed? a. 8 O b. 1 c. 7 O d. 2 O e. 16

Which statement is TRUE regarding the glycolytic pathway? a. It includes five phosphate transfer reactions. b. All of the enzymes that are regulated by product inhibition. c. It includes reactions catalyzed by three isomerase enzymes. d. All of the enzymes are regulated by high ATP concentratrion

E.coli can grow using various strategies to harvest energy. It can use fermentation pathways or cellular respiration either anaerobic or aerobic cellular respiration. Which pathway would provide the bacteria with the most loaded up ATP and why? A. Fermentation Because it harvests the most ATP  B. Anaerobic cellular respiration Because this is the quickest way to get ATP  C. Fermentation Because they use the energy in lactic acid  D. Aerobic cellular respiration Because oxygen is the best, most efficient electron acceptor to ultimately load up ATP
