Osmosis

In simple words, osmosis is the slow, gradual movement of a liquid through a membrane. But there are nuances to this process. For instance, there has to be an imbalance in the distribution of solute in the liquid on either side of the membrane, which has to be semipermeable. The liquid in the region with a lower solute concentration moves to the region with a higher concentration, thereby displacing the solution in the process. The objective is to equalize the concentration of molecules on both sides of the membrane; the displacement of liquid can be viewed as a byproduct of this equalization. Since there is no energy required to carry osmosis, it is considered a passive process.

**Please just answer the questions no need for explanation** 1) What effect would the toxin have on a cell with a non-excitable membrane in the man's body? Answer choice (Hyperpolarization, Afterhyperpolarization, No effect, Depolarization) b)True/false A cell membrane can have a membrane potential of 0mV c) True/false If the effect of EPSPs from many synapses outweighs the effect of many IPSPs from many synapses, threshold potential can be reached at the initial segment. d) true/false Under normal conditions, one EPSP, from a single synapse on a dendrite, can stimulate an action potential at the initial segment. e) True/false A cell affected by tetrodotoxin would have an action potential firing rate in the initial segment of the axon of about 100 action potentials per second
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.
For most neurons, the extracellular concentration of chloride ions (Cl-) is 108 mM, whilethe intracellular concentration of Cl- is 5 mM.If the plasma membrane becomes more permeable to Cl-, would there be Clinflux or Cl- efflux at an RMP of -70 mV? Why?
Let’s say that the intracellular tonicity is 300 mosm. Checkmark the correct response to what would happen to the cell when it is placed in the following solutions prepared from sucrose (impermeable), NaCl (impermeable), and urea (permeable). Solution Nothing Swell Shrink 100 mM sucrose 200 mM NaCl 300 mM urea 300 mM NaCl 100 mM sucrose + 100 mM NaCl 100 mM urea
Please answer both questions: 1) The sodium-potassium pump: a) equalizes the charge distribution across the cell membrane. b) transports K+ into the cell where it is in high concentration. c) requires very little energy expenditure on the part of nerve cells. d) establishes concentration gradients across the cell membrane. 2) Membrane potentials are always expressed comparing the inside of the cell relative to the outside of the cell. The resting membrane potential is -70 mV because the inside of the cell accumulates ions with negative charges. a) True b) False
If sodium permeability were to increase compared to normal what would be the resulting effect on the membrane potential 1.The charge on the inside of the cell becomes less negative compared to resting conditions and hyperpolarizes 2.The charge on the inside of the cell becomes more negative compared to resting conditions and hyperpolarizes 3.The charge on the inside of the cell becomes less negative compared to resting conditions and depolarizes 4.The charge on the inside of the cell becomes more negative compared to resting conditions and depolarizes
