Question

The (Na+-K+)-ATPase

A) is a voltage gated channel

B) an antiporter

C) maintains the intracellular [Na+] higher than the extracellular [Na+]

D) consumes ADP

E) binds Na+ and K+ simultaneously

Expert Solution

Step 1

(Na+-K+)-ATPase ( Sodium- Potassium) ATPase is also called as sodium- Potassium pump. It is a primary active transport and an example of P-type ATPase pump. It also act as enzyme like ATPase. It maintains the permeability of the cell membrane. It transport only ions 3 Na+ ions out and 2 K+ in the cell by the hydrolysis of ATP.

The rate at which the Na+K+ pump operates is not constant but is controlled by a combined effect of changes in ICF Na+ concentration and ECF K+ concentration. Do you think the changes in both ICF Na+ and ECF K+ concentration following a series of action potentials in a neuron would accelerate, slow down, or have no effect on the Na+K+ pumps in this cell?

Which of the following happens if the concentration of potassium in the extracellular fluid increases too much?A) Potassium would be taken up by the oligodendrocytes, so no net change in signaaaling would result. B) No signaling could occur. C) The Neuron would become hyperexcitable D) The sodium pumps would immediately fix the situation, so no net change in signaling would result.
Severe burns, particularly third-degree burns that damage a significant portion of the body surface, can result in the release of sodium from damaged cells into the bloodstream leading to hypernatremia. Note: Words with the suffix '-emia' generally indicate a presence of a substance or condition in the blood. Question: Based on this information, which of the following statement/s is/are true? ☐ Hypernatremia would lead to a greater Na* influx through voltage-gated Na* channels. This increased Na* influx would cause the cell to reach threshold faster and increase cell excitability. ☐ Hypernatremia can result in more negative resting membrane potential due to the reduced efflux of Na+ ions. Consequently, this may lead to a decrease in the rate of action potential generation in excitable cells. Hypernatremia can result in a more positive resting membrane potential due to the increased influx of K+ ions. Consequently, this may lead to a decrease in the rate of action potential generation…

The fight-or-flight reaction prepares an animal to Pesponu Lu a threatening situation, by either fighting or running away. One aspect of this response is changes in blood flow such that the skeletal muscles and heart receive higher blood flow (vessels dilate) while digestive organs receive less (vessels constrict). A) Which signal molecule(s) is/are involved in this response, and how do they produce these changes in blood vessels? Briefly explain how this example illustrates how different cells are able to use the same ligands in different ways.
