[Answer] In this activity the solutes were transported through the dialysis membrane by _______. facilitated diffusion osmosis simple diffusion active transport

Answer: simple diffusion
In this activity the solutes were transported through the dialysis membrane by _______. facilitated diffusion osmosis simple diffusion active transport
The nature of biological membranes especially that of its lipids is amphiphilic as they form bilayers that contain an internal hydrophobic layer and an external hydrophilic layer. This structure makes transport possible by simple or passive diffusion which consists of the diffusion of substances through the membrane without expending metabolic energy and without the aid of transport proteins.

Primary active transport also called direct active transport directly uses metabolic energy to transport molecules across a membrane . Substances that are transported across the cell membrane by primary active transport include metal ions such as Na + K + Mg 2+ and Ca 2+.These charged particles require ion pumps or ion channels to cross membranes and distribute through the body.
Facilitated diffusion is the passage of molecules or ions across a biological membrane through specific transport proteins and requires no energy input. Facilitated diffusion is used especially in the case of large polar molecules and charged ions; once such ions are dissolved in water they cannot diffuse freely across cell membranes due to the hydrophobic nature of the fatty acid tails of the …
Tue Jan 08 2002 13:30:00 GMT-0500 (Eastern Standard Time) · Facilitated diffusion (also known as facilitated transport or passive-mediated transport ) is the process of spontaneous passive transport (as opposed to active transport ) of molecules or ions across a biological membrane via specific transmembrane integral proteins. Being passive facilitated transport does not directly require chemical energy from ATP hydrolysis in the transport …
Osmosis (/ ɒ z ˈ m oʊ. s ɪ s /) is the spontaneous net movement of solvent molecules through a selectively permeable membrane into a region of higher solute concentration in the direction that tends to equalize the solute concen…
