Textbook Question
Chapter 11.3, Problem 4CC
WHAT IF? → If you exposed a cell to a ligand that binds to a receptor and activates phospholipase C, predict the effect the IP3-gated calcium Channel would have on Ca2+ concentration in the cytosol.

Need help, please. I know the answer isn't mitotic spindle or secretory and endocytic vesicle transport. I
think the answer is option C, axon stiffening, and neurotransmitter vesicle transport, but I am not 100%
sure.
What function of the microtubule motor proteins dynein and kinesin is
blocked by the use of colchicine to treat gout?
Select one:
O a. mitotic spindle
b.
secretory and endocytic vesicle transport
c.
axon stiffening and neurotransmitter vesicle transport
O d. ER, Golgi, and mitochondria movement
. What would happen in each of the following cases? Assume in each case that the protein involved is a soluble protein, not a membrane protein.
You add a signal sequence (for the ER) to the N-terminal end of a normally cytosolic protein.
You change the hydrophobic amino acids in an ER signal sequence into charged amino acids.
You change the hydrophobic amino acids in an ER signal sequence into other hydrophobic amino acids.
4 You move the N-terminal ER signal sequence to the C-terminal end of the protein.
From the image. Do you think that a membrane potential exists for this synthetic plasma membrane? If your answer is “yes,” please indicate whether it is negative or positive at the region closer to the inner leaflet of the plasma membrane. Explain your reasoning.
