When testing the effect of molecular weight on diffusion, the hydrochloric acid and ammonia molecules were placed at different ends of a sealed tube. The ammonium chloride that formed when the molecules diffused towards each other and met was closer to the ammonia end of the tube. TRUE OR FALSE? Diffusion continues to occur until there is an equal concentration of particles on both sides of a semi-permeable membrane. TRUE OR FALSE? Diffusion is the spontaneous net movement of particles...

I did a simple experiment regarding osmosis and the rate of diffusion along a concentration gradient. I practiced changes of weight of dialysis bags used as cellular models. My last measurement of Bag A, which contained 10 ml of 1% sucrose in a beaker of 10%sucrose and water, ended up having a total weight of 28.1 grams after 60 minutes. This was a -0.5 change in weight from the 45 minute interval where I calculated the weight. I am just...

Diffusion Is a passive process of transport. A single substance tends to move from an area of high concentration to an area of low concentration until the concentration is equal across a space. Facilitated transport Facilitated diffusion is the process of spontaneous passive transport of molecules or ions across a biological membrane via specific transmembrane integral proteins. Channels The integral proteins involved in facilitated transport are collectively referred to as transport proteins, and they...
