The graph here shows the $\mathrm{pH}$ difference across the inner mitochondrial membrane over time in an actively respiring cell. At the time indicated by the vertical arrow, a metabolic poison is added that specifically and completely inhibits all function of mitochondrial ATP synthase. Draw what you would expect to see for the rest of the graphed line over the next short period of time. Explain.

Step 1
The ATP synthase is responsible for the production of ATP in the mitochondria. It does this by using the proton gradient across the inner mitochondrial membrane, where protons flow from the intermembrane space (high concentration) into the mitochondrial matrix Show more…

DRAW IT The graph here shows the pH difference across the inner mitochondrial membrane over time in an actively respiring cell. At the time indicated by the vertical arrow, a metabolic poison is added that specifically and completely inhibits all function of mitochondrial ATP synthase. Draw what you would expect to see for the rest of the graphed line, and explain your graph.

DRAW UU The graph here shows the pH difference across the inner mitochondrial membrane over time in an actively respiring cell. At the time indicated by the vertical arrow, a metabolic poison is added that specifically and completely inhibits all function of mitochondrial ATP synthase. Draw what you would expect to see for the rest of the graphed line, and explain your reasoning for drawing the line as you did.
The adjoining graph shows muscle phosphofructokinase activity as a function of ATP concentration in the presence of a constant concentration of fructose 6 -phosphate. Explain these results and discuss how they relate to the role of phosphofructokinase in glycolysis. (GRAPH CAN'T COPY)
