Science / Marine Biology / Osmosis: The movement of pure water across a membrane from a compartment with relatively low dissolved ions to a compartment with higher concentrations of dissolved ions

Reverse Osmosis

Science / Chemistry / Reverse Osmosis: Solvent molecules flow spontaneously from a dilute solution through a semipermeable membrane to a more concentrated solution (osmosis). In reverse osmosis, pressure is applied to the more concentrated MORE


Science / Biology / Chemiosmosis: The process by which ATP is produced in the inner membrane of a mitochondrion. The electron transport system transfers protons from the inner compartment to the outer; as the protons flow back to the MORE


Science / Biology / Mitochondria: Self-replicating membrane-bound cytoplasmic organelles in most eukaryotic cells that complete the breakdown of glucose, producing NADH and ATP (singular term: mitochondrion). The powerhouse of the cel MORE


Science / Biology / Chloroplasts: Disk-like organelles with a double membrane found in eukaryotic plant cells; contain thylakoids and are the site of photosynthesis. ATP is generated during photosynthesis by chemiosmosis. MORE


Science / Biology / Osmoregulation: The regulation of the movement of water by osmosis into and out of cells; the maintenance of water balance within the body. MORE

Osmotic Pressure

Science / Biology / Osmotic Pressure: Pressure generated by water moving by osmosis into or out of a cell. MORE
