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.

hen an action potential arrives at the nerve terminal of a neuromuscular junction, which of the following statements best describes the events that occur? Depolarisation of the nerve terminal causes the release of ACh which activates nicotinic receptors on the skeletal muscle membrane to cause Ca2+ entry and muscle contraction. Depolarisation of the nerve terminal opens voltage-gated Ca2+ channels, Ca2+ entry brings vesicles containing ACh to the membrane which form fusion pores causing the release of ACh which activates voltage-gated Na+ channels at the end-plate. Depolarisation of the nerve terminal opens voltage-gated Ca2+ channels, Ca2+ entry brings vesicles containing ACh to the membrane which form fusion pores causing the release of ACh which binds to muscarinic receptors at the end plate. Depolarisation of the nerve terminal opens voltage-gated Ca2+ channels, Ca2+ entry brings vesicles containing ACh to the membrane which form fusion pores…
