How do molecules get into cells
WebIn animals, glucose molecules have to be moved across the gut wall into the blood. The glucose molecules in the intestine might be in a higher concentration than in the intestinal cells and blood ... WebLarge molecules, such as proteins and solid particles, are often transported by pinocytosis. The cell membrane engulfs a particle or protein molecule outside the cell, and brings it into the cell. Although inefficient, pinocytosis operates in the slow absorption of proteins and particles in the intestine and respiratory tract.
