Based on the model of movement through the phospholipid bilayer, what is the most likely choice for the substance crossing the membrane? A) water B) glucose C) oxygen gas D) sodium ions

The correct option is C) oxygen gas

Explanation:

The cell membrane is a phospholipid bilayer membrane which is selectively permeable. This selectively permeable membrane allows the movement of small, uncharged molecules or substances easily through it by the simple method of diffusion. Hence, among the options mentioned, oxygen gas which is small and uncharged will be easily be able to pass through the cell membrane by the process of diffusion. Other molecules, like large molecules, require other methods such as carrier proteins for movement across the cell membrane.
