1. How do uncoupling agents like DNP (dinitrophenol) affect the electron transport chain and the activity of the F0F1 ATP synthase.?
a) They provide an alternative path for protons to re-enter the mitochondrial matrix, so ATP synthesis decreases. Electron flow and proton pumping are not inhibited.
b) They block the flow of electrons, so protons aren't pumped, and ATP synthesis ceases
c) They remove electrons from the chain, so less protons are pumped, and ATP synthesis ceases
d) They block the flow of protons through the ATP synthase, so ATP synthesis ceases. Electron flow and proton pumping are also halted as a result
The volume of a sample of gas, initially at 25oC, increase from 158 ml to 450 ml. What is the final temperature (C) if the pressure in the container is kept constant.
Draw several Lewis structures and determine the geometry, bond angle, and hybridization about the central atom
An apparatus to be used in a decomposition study was filled with N2 gas at 400.00 mm Hg and 400.0 deg C. The volume of the apparatus was 400.0 mL.
