37. What process(es) is/are required for phospholipids to flip-flop across the lipid bilayer?A) The process requires an enzyme called flippase. B) The process occurs spontaneously, requiring no energy. C) The process occurs spontaneously and requires the flippase enzyme. D) The process requires energy. E) The process requires energy and the flippase enzyme. 

Cellular respiration produces the most energy in the form of ATP from which of the following? glycolysis the citric acid cycle substrate-level phosphorylation production of lactate oxidative phosphorylation

36. The ultimate source of energy for photosynthetic reactions in a plant isA) catabolism. B) the sun. C) plants. D) glucose. E) glycogen.

The process that forms the electrochemical gradient during photosynthesis is the production of H+   in the stroma during NADPH production. movement of water by osmosis. hydrolysis of ATP. production of water from oxygen in the thylakoid lumen. pumping of  H+ into the thylakoid lumen.

The route that most accurately describes secretory protein movement through the endomembrane system would be Golgi apparatus→smooth endoplasmic reticulum →lysosome→vesicles→plasma membrane. nuclear envelope→vesicles→Golgi apparatus→rough endoplasmic reticulum→plasma membrane. rough endoplasmic reticulum→vesicles→ Golgi apparatus→vesicles →plasma membrane. plasmid→plasma membrane→nuclear envelope→smooth endoplasmic reticulum→ lysosomes→rough endoplasmic reticulum→smooth endoplasmic reticulum→vesicles→plasma membrane.
