Cell Equilibrium

Cell Equilibrium

To function properly the cell must maintain a stable internal environment; therefore, transfer of materials has to be achieved without an excessive buildup of chemicals. When particular molecules are needed-for example, glucose-the cell will take these in and discard other materials to preserve equilibrium. There are three types of transport when maintaining cell equilibrium. Passive transport occurs when chemicals concentrated outside the cell cause a flow of small molecules to push through the membrane until a balance exists. This process, known as diffusion, is the basis of the intake of digestive products by cells lining the intestines. Active transport is the process, using chemical energy, by which the cell takes in larger molecules that would otherwise be unable to enter in sufficient quantities. Carrier molecules within the cell membrane bind themselves to incoming molecules, rotate around them and release them into the cell. This is the means by which the cell absorbs glucose. Active transport may upset stability, but the cell compensates by shedding other matter. The movement of water through the cell membrane from areas of low to high chemical concentration is called osmosis. This alternative process provides for dilution of chemicals-unable to cross the membrane by diffusion-to maintain equilibrium within the cell.

Active transport results in a STEADY STATE away from equilibrium being attained. EQUILIBRIUM is attained when the cell is DEAD.

[sam061091]

your active transport discription and explination is incorrect and misleading. The carrier molecule is a carrier protien inbedded in the phospholipid bilayer, it does not rotate; the substrate molecule binds to the protien, ATP is then asserted to the carrier protien and the chemicle structure changes thus causing the molecule to move. the ATP is turned into ADP becuase of the energy transphere to the protien, it then goes back to the mitochonidria and gets changed back into ATP lol but still kl

i know what all these things are anyway but that just confused me lol dunno why just his voice i think

[jimmykay01]

heard of sarcasm? ofcourse equil. it obtained when the cell is dead, wat the fuck else would be happening...

[gastonlegrand]

Yes! A basic tenet of thermodynamics is that no work can be done by a system at equilibrium. Hence a dead cell is at equilibrium. Your final remark shows that you are a pathetic retard who should be in rehab.

you really dont know how to spell any thing

[jimmykay01]

Equilibrium is obtained when the cell is dead? you fucking dumbass

[ProRobzy]

YOu stupid arsehole

[Nickisrad34]

i hate this im doing ferensics or hoever the fuck its spelld but neways yea i hate it we have a test tamarow so im looking on here for more help

[RLhockey203]

i hate biology exams
