Potassium flows the cell through leak channels, its gradient. into, down out of , up into , up out of , down

There are differences in Na+, K+, and Cl- ion concentrations across the membrane.  Knowing that ions like to flow down their respective concentration gradients explain how the movement of Cl- and K+ ions can result in membrane hyperpolarization.

The Na+/glucose cotransporter in ION-GRADIENT-DRIVEN ACTIVE TRANSPORT, against its gradient. Na+/glucose Na+/K+ glucose/glucose Na+/Na+ moves down its gradient and

"Transporters saturate at high concentrations of the transported molecule when all their binding sites are occupied; channels, on the other hand, do not bind the ions they transport and thus the flux of ions through a channel does not saturate." is true or false.

"Sodium is usually more concentrated outside the cell than inside. Therefore, it is transported into the cell through this (name the transport process)" A Moving to another question will save this response. «< Question 57 of 80 tv Aa MacBook Air 80 DII F2 F3 F4 F6 F7 FB F9 F11 %23 $ 3 4 9 - E R Y { D J K C V command option .... * 00 ト

Nervous cells use both chemical and electric communication mechanisms, whereas the endocrine system typically uses for communication

difference between channels and transporters is that O Only channels allow for the passage of solutes against their electrochemical gradient. OTransporters allow for a greater rate of transport across a membrane than channels do. O Only channels allow for the transport of ions. Transporters must undergo a conformational change upon binding to the solute.

describe in detail:how the Dopamine transporter (DAT)transporter works whether it is an active or passive transportera specific type of cell that it can be found in and why it is important in this cell typeconsequences for body function when this transporter type fails (due to a mutation that makes it non-functional)

Which of the following regarding the sodium potassium pump is FALSE?   It tends to be found on the apical plasma membrane of polarized cells It transports three sodium ions to the outside of the cell It transports two potassium ions to the inside of the cell. It helps to maintain unequal distribution of ions across the plasma membrane
