Diffusion Flashcards
1
Q
Diffusion in respiration
A
During respiration Oxygen is used up.=low concentration of oxygen
Therefor oxygen is let in which then diffuses into cells
2
Q
Plant Cells
A
Semi-permeable membrane. Selected gases are allowed to permeate through the membrane
3
Q
Diffusion
A
Oxygen diffuses in and is met by glucose. Reacts during respiration.
CO2 and H2O are created.
CO2 diffuses out water is urinated and breathed out.
4
Q
What is a concentration gradient?
A
When something more concentrated mives to an area of lower concentration.
Eg. If 1 mole CO2 is inside cell and only 1/2 mole is outside CO2 is let out to balance the concentration. This is carried out along a CONCENTRATION GRADIENT
