Document Summary

It"s always going to be using transporters inserting transporters in specific locations in cells to move ions so that water can flow osmotically. In any case we find that it"s like that. Osmoconformers vs osmoregulators be comfortable with these 2 terms. This doesn"t mean that the composition of the ions/ solutes on the inside is the same on the outside. It means the overall concentration is the same. This becomes important if you live in a marine environment na/k how many physiological processes those can effect. Not necessariliy an ionic regulator don"t need to go into detail here. Water vs. solute need to be confident with this water is simply going to follow we cannot actively transport water in all cases. There are transporters like aquaporins but those just facilitate the movement of water not active transport! Euryhaline orgs are able to adapt to a wide range of salinities or else they die they are good regulators.
