Question
Chapter 13, Problem 17P
Interpretation Introduction
Interpretation:
The reason for the flow of a small number of sodium ions through the Na+ channel needs to be explained.
Concept introduction:
Diffusion is defined as the movement of particles such as atoms, molecules or ions from a higher concentration region to a lower concentration region. This process is continued till the concentration of the particles is same on both sides of the membranes or boundary.
In the body, the diffusion of ions/molecules/atoms takes place inside or outside of the cell through the cell membrane.

- very cold climates. When marathoners or other endurance athletes sweat heavily and drink a large amount of pure water, their sodium level drops. The resulting condition, called "water intoxication," can be fatal. Why is maintaining the sodium level so important? . Drinking alcohol inhibits ADH secretion. What effect will drinking a beer have on the permeability of kidney tubules to sodium? To water? CHAPTER 40 MAINTAINING THE INTERNAL ENVIRONarrow_forwardFrog poison. Batrachotoxin (BTX) is a steroidal alkaloid from the skin of Phyllobates terribilis, a poisonous Colombian frog (the source of the poison used on blowgun darts). In the presence of BTX, Na+Na* channels in an excised patch stay persistently open when the membrane is depolarized. They close when the membrane is repolarized. Which transition is blocked by BTX?arrow_forwardMultiple Choice. Imagine a solution containing only water, sodium, and glucose. If a voltage is applied to the solution, glucose would move: (a) There would be no net movement of glucose (b) In the opposite direction of sodium (c) In the same direction and speed as sodium (d) In the same direction as sodium, but slower. (e) In the same direction as sodium, but faster.arrow_forward

- Please help me with this question. More than one answer may be correct. THe graph relating to the information is included below. The above figures show the rate of actin polymerization in the presence of various concentration of profilin (Pfn). In the top figure, flourescence intensity is a measure of total actin that has been polymerized, and this is plotted versus time in seconds. The shade of blue of the lines in the top figure correspond to the shaded blue bars representing various concentrations of profilin in the lower figure. The lower graph shows the initial rates of polymerization of actin plotted again concentration. Which of the following is true: Question 21 options: profilin in a molecular motor profilin is a promoter of actin polymerization profilin replaced G-actin in an F-actin strand and breaks the filament profilin is an inhibitor of actin polymerization profilin binds to G-actin, preventing it from polymerizingarrow_forwardPlease ASAP.
