How do molecules get into cells
WebApr 14, 2024 · Your cells dump their waste/toxins into the tiny spaces between them that are filled with extracellular fluid. Throughout most of the body, this is called lymphatic fluid; in your brain and central nervous system it is called the cerebrospinal fluid (CSF). The CSF drains back into your lymphatic fluid, which then enters back into your blood.

WebMar 5, 2024 · Small nonpolar molecules can easily diffuse across the cell membrane. However, due to the hydrophobic nature of the lipids that make up cell membranes, polar molecules (such as water) and ions cannot do so. Instead, they diffuse across the membrane through transport proteins.
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.
