Which of the following molecules can diffuse through the mem
Which of the following molecules can diffuse through the membrane faster?
CO2, CH4
Sugar, glucose
H2O, H3O
Ca2+, Ka1+
Solution
H20 Water. oxygen is a small molecule and its non -polar makes the water molecules ,can pass through the membrane easyly by water diffusion calle osmosis.C02 ,the by product of cell respiration,is small enough to readily
diffuse out of a cell. small uncharged lipid molecules can pass easyly the membrane.
Large and charged molecules show slow movement.
Glucose also move easyly across the membrane.
