Very Very Tough Question?

Question

What function might each of the 3 types of diffusion serve in a multicellular organism- for example, a human or a tree?

(simple diffusion, facilitated diffusion, and Active Transport

Yes I'm taking AP bio

Sam how do you remember all the info. How do you study? And how often..

Answer 1

um ahh u meaning diffusion as in seperate.......if so would hurt very bad fattalitys may occur(will)

Answer 2

I don't know much about trees so I will try to answer for humans. First simple diffusion, a great example would be the exchange of gasses in the lungs all by simple diffusion. Now facilitated diffusion is also called carrier-mediated diffusion, because a substance transported in this manner cannot pass through a membrane without a specific carrier protein helping it. A good example would be glucose, and amino acids entering a cell requires a carrier protein. Active transport is transport that requires ATP energy. A good example is the sodium-potassium pump that each of our cells has. It is pumping both sodium and potassium against their concentration gradient so it takes energy to do this. Passive diffusion is transport down the concentration gradient so no additional energy is required.

Answer 3

teh types of diffusion will be acting across each cell even in a multicellular organism:

simple diffusion: exchange of gases across the pulmonary capillary membrane for effective gas exchange!

facilitated diffusion: entry of glucose into red blood cells

active transport: Na K atpase to maintain the membrane potential

Answer 4

simple diffusion would affect a human or a tree in that it would allow a cell to get rid of excess concentration(of sugar/glucose)

facilitated diffusion would allow a human/ tree to push away only certain molecules(you'll have to look those up) to keep the cell from lyseing.(exploding)

Active transport would allow a human/tree to push out OR take in excess concentration to created an isotonic enviroment.(concentration is same on inside/outside of the cell)

Are you taking AP Bio?

Answer 5

I have no idea. But ask me anything in Psychology I have a background degree in that :)
