Transport Process - Coggle Diagram
One fundamental aspect of life itself is the ability to transport specific substances to particular site.
Transport processes consume energy, and many are driven by the exergonic breaking of ATP's high-energy phosphate-bonding orbitals.
-
Diffusion
Movement of by which the materials move from higher concentration to areas where they are relatively low concentration
-
osmosis
Osmosis is a passive transport process during which water moves from areas where solutes are less concentrated to areas where they are more concentrated.
-
Active Transport
The forced pumping of molecules from one side of a membrane to the other by means of molecular pumps located in the membrane.
-
All cell membranes in transport process; are plasma membrane governs movement of material into and out of the cell.
Membranes are of three types: freely permeable membrane, completely impermeable membranes, differentially or selectively permeable membranes.
Water molecules, even though highly polar, pass through all membranes, but their movement is more rapid if the membrane has protein channels called aquaporins.
Water potential
The chemical potential of water; a measure of the ability of a substance to absorb or release water relative to another substance. It is pronounced as "sigh".
Components: osmotic potential, pressure potential, matric potential.
