Diffusion

[@AmoebaSisters]

We often put a time-stamped table of contents in the video description (check out our video description), but we thought we'd pin it here too for convenience :) 0:57 Relating intro event to diffusion 1:45 Diffusion explained 2:57 Molecules still move at equilibrium! 3:33 Diffusion is passive transport 3:45 Facilitated diffusion 4:22 Some factors that can affect rate of diffusion 6:35 Why care about diffusion?

Amoeba Sisters please stop. i hate how you constantly make gaming references. We watch you so much in biology. I’m sorry but please. The gaming references kill me. Literally portal references. I don’t even want to take credit for the class anymore because of your Naruto and portal references. Thanks. 🙏🐪

Staright facts

[@ericcartman9180]

so true

[@Celti_]

1:47 Diffusion is when the net movement of a substance travels DOWN its concentration gradient. This means it moves from a high concentration to a low concentration. Diffusion doesn't just happen in water, it happens when you spray an air freshener. 2:46 Net movement = overall movement but it doesn't mean the molecules can't move around the other direction or stop moving altogether. The overall/net movement is from a high concentration to low concentration until equilibrium is reached. Diffusion is a passive transport, meaning an input of isn't required. Kinetic (movement) energy is enough. Passive transport does not require added energy. 3:44 Facilitated diffusion is a type of diffusion when molecules still have a net movement from a high concentration to a low concentration but because the ion sizes are too large to travel directly through the plasma membrane, the ions travel through proteins. 4:21 Factors that can affect the speed of diffusion: temperature (higher temperature would mean more movement of the molecules, increasing diffusion rate), distance (the greater the distance that needs to be travelled, the slower the diffusion rate), characteristics of the solvent (is the solvent dense? This could slow to molecules down and decrease the diffusion rate), characteristics of the substance travelling (substances with greater mass will have a lower diffusion rate compared to a substance with less mass), characteristics of the barrier/plasma or cell membrane if it's passing a barrier (small non polar substances pass through a cell membrane easier than large polar substances) and the surface area/thickness of the cell membrane (a large surface area and thin membrane = faster diffusion compared to small surface area and thick membrane).

Thank you for this video! As a college bio student its nice to hear another explanation of stuff other than just lecture classes. The fish story at the beginning is also a great way to help get people interested and to stay focused on the content you are teaching as it is pretty difficult for me to stay focused when tons of info is being thrown at me. Thank you for helping me study for my exam!

[@coolbeans921]

Fun fact: a more natural way to treat ich is to turn the heat in an aquarium up to 86 degrees C as that is the temperature that ich dies. Leave it there for a few days and your fish will be cured without harming other life in the aquarium such as beneficial bacteria which is crucial to converting waste into less toxic substances such as Nitrate. Thanks for the vid!
