Treatment of inside-out vesicle preparation with sodium dodecyl sulfate causes decrease in oxidative phosphorylation. Why?
Treatment of inside-out vesicle preparation with sodium dodecyl sulfate causes decrease in oxidative phosphorylation. Why?
Homework Answers
Yes because SDS leads to membrane disruption. This will lead to a decrease in an oxidative phosphorylation as Oxidative phosphorylation complexes are located in the inner membrane of mitochondria in the cristae.
The topography of the inside out vesicle is changed so the inner membrane and outer membrane will be changed. there will be no proton gradient so there will be no generation of ATP.

3. Sodium dodecyl sulfate (SDS) polyacrylamide gel electrophoresis a. After pouring the SDS polyacrylamide gel, you realize that instead of 2 ml, you used 4 ml of 30% acrylamide/bisacrylamide solution for the preparation of the separating gel (in both cases for 5 ml, total gel volume). How would this affect the separation of your proteins during SDS PAGE? Explain your answer! b. You have to remake the gel and are now making sure just to add...

3. Oxidative phosphorylation (50 pts) A) In his studies of alcoholic fermentation by yeast, Louis Pasteur noted that the sudden addition of oxygen (O,) to a previously anaerobic culture of fermenting grape juice resulted in a dramatic decrease in the rate of glucose consumption. This "Pasteur effect can be counteracted by the addition of 2.4-dinitrophenol (DNP), an uncoupler of oxidative phosphorylation. 0) Why would the yeast cells consume less glucose in the presence of oxygen?

1. Extensive treatment with phospholipase A2 of a right-side-out, sealed plasma membrane vesicle preparation from a human fibroblast cell line hydrolyzes a fraction of the lipids in each phospholipid class (see table below). Note that phospholipase A2 hydrolyzes the ester linkage on the fatty acyl chain at the 2-position of a phosphoglyceride. Assuming that the accessible substrate lipids are present on both leaflets (monolayers) of the plasma membrane, calculate the phospholipid composition of each leaflet. Report the calculated percentage of...

Question 1 1 pts When acetic acid and sodium bicarbonate react, why does the total mass decrease? the bubbling of the reaction mixture always causes spattering of the sodium bicarbonate which causes the overall mass to decrease. O a gas is released in the reaction so it's mass is not part of the reaction mixture after the reaction is complete some of the acetic acid gets consumed in the reaction which causes the overall mass to decrease the total mass...
