Question 1 of 10 0.5/ 0.5 Points I ons are unable to freely cross membranes. When charged atoms (ions) are  pumped across cell membranes by specialized proteins, an electro-chemical  gradient is formed. Electro-chemical gradients are a form of order, because  more of a particular ion is found on one side of a membrane than on the other  side. If the ions are allowed to cross the membrane through a specialized  protein, A. A flagellum can be forced to rotate, moving the cell. B. A fuel molecule can be pumped into the cell, against its concentration gradient. C. Other forms of work, such as the formation of bonds within molecules, could theoretically be driven by the released energy. D. All of the choices are correct. Answer Key: D Question 2 of 10 0.5/ 0.5 Points The purpose of both alcohol fermentation and lactic acid fermentation is to A. reduce NAD+ to NADH. B. Oxidize NADH to NAD+. C. Phosphorylate ADP to ATP. D. Oxidize fuel molecules to release energy. Answer Key: B Question 3 of 10 0.5/ 0.5 Points Cells that perform respiration can make more ATP per glucose. Where is most of  this ATP made?
