1. Alcohol is lipophilic as it is mostly non-polar, and hence it diffuses into cells very readily. The glucose which comprises sugar is both polar and very large, and hence it may only diffuse into a cell through a transport protein embedded on the membrane.
2. Phagocytosis involves the vesicular internalisation of solid particles. A particle that has been transported into the cell by phagocytosis is enveloped in a vesicle but it is not considered a part of the cytosol until lysosomes hydrolyse it by fusing onto the vesicle and degrading it .
