The electron transport chain (ETC), or respiratory chain, is linked to proton movement and ATP synthesis. Select the STATEMENTS that ACCURATELY describe the electron transport chain. (True/False)
a)Electron transfer in the ETC is coupled to proton transfer form the matrix to the intermembrane space. b)Electrons generated by he citric acid cycle in the mitochondrial matrix enter the ETC. c)The outer membrane of mitochondria is readily permeable to small molecules and hydrogen ions. d)Electron carriers in the mitochondrial matrix include ubiquinone (coenzyme Q), FMN, and cytochrome c. e)Prosthetic groups, such as iron-sulfer centers, are directly involved with electron transfer. f)Electron carriers are organized into four complexes of proteins and prosthetic groups. g)The reactions of the ETC take place in the outer membrane of mitochondria.

Which pair of quantities includes one quantity that increases as the other decreases during simple harmonic motion?

To understand the behavior of the electric field at the surface of a conductor, and its relationship to surface charge on the conductor. a conductor is placed in an external electrostatic field. the external field is uniform before the conductor is placed within it. the conductor is completely isolated from any source of current or charge. part a: which of the following describes the electric field inside this conductor? it is in the same direction as the original external field.it is in the opposite direction from that of the original external field.it has a direction determined entirely by the charge on its surface.it is always zero. part b: the charge density inside the conductor is: 0non-zero; but uniformnon-zero; non-uniforminfinite part c: assume that at some point just outside the surface of the conductor, the electric field has magnitude e and is directed toward the surface of the conductor. what is the charge density η on the surface of the conductor at that point? express your answer in terms of e and ϵ0
