Predict what would happen if you treated cells with Cytocholasin D when the concentration of G-actin is lower than the critical concentration for either end.
Homework Answers
Actin is involved in muscle contraction, cell division, organelle movement etc. G-Actin is a free monomer. It forms F-Actin polymers.Below critical condition, there is depolymerization.
Cytochalasin D is a fungal metabolite. It prevents addition of monomers to a polymerized microfilaments. Thus, the dynamics of actin is disrupted by Cytochalasin D.

Compared to the normal situation, in which actin monomers carry ATP, what do you predict would happen if actin monomers that bind a nonhydrolyzable form of ATP were incorporated into actin filaments? (a) Actin filaments would grow longer. (b) Actin filaments would grow shorter because depolymerization would be enhanced. (c) Actin filaments would grow shorter because new monomers could not be added to the filaments. (d) No change, as addition of monomers binding...

1. If you add short actin filaments marked by bound myosin heads
(myosin-decorated filaments) to a solution with an excess of actin
monomers, wait for a few minutes, and then examine the filaments by
electron microscopy, you see the picture shown in Figure 16-5.
A. Which is the plus end of the myosin-decorated filaments and
which is the minus end? Which is the "barbed" end and which is the
"pointed" end? How can you tell?

You have a 100X stock of cytochalasin (a drug that depolymerizes actin). You want to treat some cells with cytochalasin and caffeine to see what happens. The cells are already in 200μl of a solution of caffeine at approximately the right concentration. How much cytochalasin would you add to the cells in caffeine?

You run a small business and would like to predict what will happen to the quantity demanded for your product if you raise your price. While you do not know the exact demand curve for your product, you do know that in the first year you charged $45 and sold 1200 units and that in the second year you charged $30 and sold 1800 units. a. If you plan to raise your price by 10%, what would be a reasonable...

CONCEPT CHECK 23-4 When some cells are treated with growth factors that act through receptor tyrosine kinases, they divide rapidly. These cells are also known to be able to respond to the hormone epinephrine, which leads to the activation of adenylyl cyclase. In addition, it is known that protein kinase A (PKA) inhibits the protein Raf in these cells. Based on this information, how do you predict that cells treated with growth factor alone will compare with cells treated simultaneously...
