DRAW IT The graph here showsthe pH difference across theinner mitochondrial membraneover time in an actively respiringcell. At the time indicated by thevertical arrow, a metabolic poisonis added that specifically andcompletely inhibits all function ofmitochondrial ATP synthase. Drawwhat you would expect to see forthe rest of the graphed line, andexplain your graph.

co S Question #6. On the right is a schematic showing the structure of complex V (ATP Synthase). The various subunits are labeled. 6A Label the figure to show the location of the mitochondrial matrix αβλαβ Y 6B On the figure indicate the direction of proton flow across the membrane in the direction of ATP synthesis. Make sure to specifically indicate through which portion of the complex the protons move. E Ab, a a cc ccc Inner membrane 6C List the specific subunits in the complex that rotate as protons flow through the complex (select from: a, b2, c, a, ß, y, 8, ɛ) 6D Rotation occurs in 120° steps. Briefly explain why this is consistent with the bind-and-change mechanism that produces ATP. In your answer, make sure to indicate the number of active sites in the complex and how rotation alters their ability to promote catalysis.

In the absence of oxygen, cells consume glucoseat a high, steady rate. When oxygen is added, glucose con-sumption drops precipitously and is then maintained atthe lower rate. Why is glucose consumed at a high rate inthe absence of oxygen and at a low rate in its presence?

Which ion gradient is used in electron transport chain to produce ATPs? What is that ATP-producing protein called?
