A. Cell engulfs molecules in cell "drinking"
a. Pinocytosis
B. Molecules helped by protein
b. Transmembrane molecules that act as carrier proteins to facilitate the movement of molecules
C. move insoluble molecules across plasma membrane
c. Insoluble molecules such as lipids are transported in vesicles
D. molecules move in and out freely from high to low concentration
d. this is diffusion, molecules such as sodium ions can move from where it's at a high concentration to where it's in a low concentration in the cell
E. cell engulfs microorganisms in cell "eating"
e. this is achieved by Phagocytosis and is done by specialist cells
F. molecules "pumped" in or out from low to high concentration
f. This is Active transport, molecules are pumped in or out of the cell against a concentration gradient. this process requires ATP
G. Oxygen, carbon dioxide in and out of cells
g. Where gases such as carbon dioxide and oxygen enter or leaves cells is called Gas exchange.
H. Transport sodium, potassium
h. sodium and potassium ions are transported around cells by Active transport and are aided by the use of sodium and potassium pumps.
I. transport of glucose and amino acids
i. glucose and amino acids can be transported in a number of ways, simple diffusion, facilitated diffusion and active transport which is facilitated by proteins in the cells. glucose and amino acids are often absorbed into cells at the PCT in the kidneys
Hope this helps to answer your question :)
