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.
