In vertebrates, motor neurons release acetylcholine (ACh), a small molecule neurotransmitter, which diffuses across the synaptic cleft and binds to nicotinic acetylcholine receptors (nAChRs) on the cell membrane of the muscle fiber, also known as the sarcolemma.
Using energy is the answer to this question :)
Since the client is throwing tantrums and outburst, it is best to calm the client but taking an action of having to talk to him or her or try to get closer to him or her will likely provoke him or her into doing what he or she is currently doing. It is best for the nurse to calm the client by having to tell him or her that the nurse will leave and will be back as soon as he or she calms down.
Answer:
The proteins will be transported through exocytosis; the carbon dioxide will diffuse through the membrane.
Explanation:
Diffusion is the passive transport of substances down their concentration gradient. The process moves the substances from the region of higher concentration to that of lower concentration. CO2 is a small molecule and does not have any charge. Small, uncharged molecules can diffuse through the lipid bilayer of the cell membrane. Therefore, CO2 can exit a cell by simple diffusion.
On the other hand, proteins are too large to be transported by diffusion across the cell membrane. The proteins are transported by exocytosis. During exocytosis of proteins, membrane-bound vesicles are formed inside the cell. These vesicles carry proteins in them and are called secretory vesicles. The membrane of the vesicles fuse with the cell membrane of cells and transport the proteins outside the cell.
