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.
In phase II of ETS diagram and label the ATP synthase along with the inner mitochondrial membrane it is sitting in. Your diagram must show the intermembrane space and the mitochondrial matrix. Describe how it works step by step
You are growing human muscles cells in the lab and you are trying to test how wellthe cells survive with decreasing concentrations of oxygen. As part of yourexperiment, you are measuring the rate of glucose use, the rate of mitochondrial ATPproduction and the pH of the solution surrounding the cells. As the concentration ofoxygen becomes lower änd lower, what changes might you expect to observe inthese cells?A. The rate of glucose use would increase, the rate of mitochondrial ATP productionwould decrease, and the pH of the solution would decrease (become more acidic).B. The rate of glucose use would decrease, the rate of mitochondrial ATP productionwould decrease, and the pH of the solution would increase (become more basic).C. The rate of glucose use would increase, the rate of mitochondrial ATP productionwould increase, and the pH of the solution would decrease (become more acidic)D. The rate if glucose use would decrease, the rate of mitochondrial ATP productionwould decrease, and…
The proton motive force is the result ofa. ATP synthase transporting protons during ATP synthesisb. an electron gradient between the matrix and the intermembranespace of a mitochondrionc. a proton gradient between the matrix and intermembrane space ofa mitochondriond. a buildup of negatively charged ions
Cyanide is a poisonous substance. Cyanide is a cytochrome c oxidase inhibitor that is competitive. The last enzyme of the electron transport chain in mitochondria is cytochrome c oxidase. One of the most common substrates for cytochrome c oxidase is oxygen.Would an increase in the concentration of oxygen affect the inhibitioncaused by cyanide?How would conditions in the mitochondrial intermembrane spacechange if cytochrome c oxidase and the electron transport chain are notfunctioning properly.. Explain why this change in conditions will be harmful to a cell.
SCIENTIFIC INQUIRY In the 1930s, some physiciansprescribed low doses of a compound called dinitrophenol(DNP) to help patients lose weight. This unsafe method wasabandoned after some patients died. DNP uncouples thechemiosmotic machinery by making the lipid bilayer of theinner mitochondrial membrane leaky to H+. Explain howthis could cause weight loss and death.

Luckily, protons (a.k.a. hydrogen ions or H+) are small enough to passively go right through a membrane, otherwise mitochondria would have to work too hard to regenerate ATP! True or False?
The proton-motive force is a measure of the potential energy generated across the mitochondrial inner membrane during electron transport. Explain the factors that constitute this potential energy, that will be converted to the chemical energy of ATP by the cell
The electron transport chain of mitochondria: O makes ATP. contains cytochromes and proteins containing flavins (FAD). O generates an H* gradient such that the outside of the mitochondrion is more basic than the inside. O is present in the outer membrane of the mitochondrion. O reduces NAD*.
