Cell Biology Final Exam (T or F & MC)0 mV - ANS-What would be the resting potential across an artificial membrane if call charged
molecules on both sides were equally permeable?
10 - ANS-If each NADH can drive the synthesis of 2.5 ATP, and FADH2 can drive the synthesis

bonds can be involved in the quarternary structure of a protein
B - ANS-In the diagram which letter represents the energy of activation for the enzyme
catalyzed reaction
CH3OH --> CH2O - ANS-Which of the following reactions is an oxidation of the substrate
Cl- - ANS-All of the following can diffuse through the cell membrane except
confocal microscopy - ANS-Suppose you want to study how the surface features of a cell
change while the cell is treated with a certain drug. What type of microscopy would you most
likely use?
Contact dependent - ANS-Delta binding to the Notch receptor is a type of ______ signaling
cytochrome c - ANS-Which component of the electron transport system is NOT embedded in a
membrane

False - ANS-Green plants have only chlorophyll as the photosynthetic pigment in their leaves
False - ANS-Histone proteins have a large number of negatively charged amino acids in their
sequence
False - ANS-In prokaryotes the electron transport chain involves the mitochondrial membrane
False - ANS-Membrane phospholipids often flip-flop across the membrane
False - ANS-Mutations in the DNA of an organism are kept to a small rate of occurrence by the
5' to 3' exonuclease activity of DNA polymerase
False - ANS-Phosphorylation of glycogen phosphorylate inactivates it
False - ANS-Proteins are transported into the MITOCHONDRIA in their completely folded
conformation
False - ANS-The Calvin cycle creates ATP and NADPH for use by the cell
False - ANS-The pyruvate dehydrogenase reaction results in the reduction of FAD+ to FADH2
False - ANS-The set of metabolic reactions in cells that help synthesize all the cellular
components are called catabolism
