12 points! describe the two major types of active transport in cells. .

1. SIMPLE DIFFUSION

Diffusion is the tendency of molecules to spread from regions of high concentration to regions of low concentration.  This movement is due to a concentration gradient.  This is the difference in concentration between two different regions.  An example - when you spray perfume in the corner of a room and eventually you can smell it everywhere.

2. OSMOSIS

Osmosis is the diffusion of water across a selectively permeable membrane from a region of high water concentration to a region of low water concentration.

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.
