Question 61 The ATP dependent sodium-potassium pump forces potassium ions the cell and sodium ions the cell. out of, out of out of into into; out of into: into
In the sodium-potassium pump: sodium and potassium both enter the cell sodium and potassium both leave the cell potassium enters and sodium leaves the cell sodium enters and potassium leaves the cell. The movements of sodium and potassium depends on concentration differences. The reticular activating system is composed of neurons that are part of the reticular formation is a loose arrangement of neurons with many interconnecting synapse. functions in the brain stem and midbrain. functions to arouse the cerebral cortex...
The sodium potassium uses energy in the form of ATP hydrolysis to move 3 sodium ions out of the cell and 2 potassium ions into the cell. The concentration of sodium inside is 14mM and outside is 143mM. The concentration of potassium inside is 157mM and outside is 4mM. Membrane potential is -50mV and temperature is 310K. Demonstrate that hydrolysis of ATP to ADP provides enough energy to move 3 sodium ions out and 2 potassium ions in to the...

1. 2. 3. Select all that apply. The sodium-potassium ion pump: hydrolyzes ATP, utilizing the free phosphate ion to temporarily bind to the transport protein. opens a channel through the membrane by phosphorylating one subunit of the transport protein. D is the only known ion pump. D is mediated by one enzyme that both hydrolyzes ATP and transports the ions. can be run in reverse, phosphorylating ADP to ATP Which of the following describes secondary active transport? O The antiport...
suggest a precipitation method for the separation of potassium ion from sodium and lithium ions
How does facilitated diffusion differ from simple diffusion? Facilitated diffusion requires ATP Facilitated diffusion requires a solute-specific protein carrier Facilitated diffusion transports solute against its’ concentration gradient Which of the following is TRUE about primary active cell membrane transport? It is a form of transport that requires a protein “pump” It is a form of transport that transports ions and/or solute against their concentration gradient It is a transport mechanism that requires energy released from the splitting of ATP by...
