Depednign on what the cell is trying to transport there could be a variety of ways for the cell to transfer materials.
If the item is small and np then it can go through the lipid bilayer.
Simple diffusion and facilitated diffusion are passive transport meaning the cell does not need energy to transfer the membrane
and active diffision means they need to spend energy.
you need transmembrane protiens to move things inside the cell
I think the answer is true
Genomics..Data mining contributes to the field of genomics..
Question 4
Which of the following would be considered a form of active transport?
o the movement of oxygen molecules from high concentration in the blood to low concentration in the cell.
O the movement of carbon dioxide from high concentrations in the cell to low concentrations in the blood.
o the movement of glucose into the cell down its concentration gradient,
o the movement of sodium atoms from low concentration in the cell to higher concentrations outside the cell.
