Why can Iodine diffuse through a cell membrane? : r/askscience

WebTwo important factors are involved in the passage of solutes across a selectively permeable membrane: 1) whether the membrane is permeable to the solute, and 2) the concentration (or electrochemical*, if ionic) gradient Solutes move across membranes by diffusion: DOWN their concentration or electrochemical (if ionic) gradient. * an ... WebThe results show that the water, glucose, and IKI molecules were small enough to pass through the selectively permeable membrane. The starch didn't leave the beaker because its molecules were too large to pass through the selectively permeable membrane's pores. Quantitative data uses numbers to measure observed changes. Webthe iodine moved into the plastic bag. Small lipid soluble molecules would move through the plasma membrane bydiffusionIn the process of diffusion, when sugar is mixed with water, equilibrium would be reachedwhen the dissolved sugar molecules are evenly distributed throughout the solution. northern hemisphere astronomy

WebCell membranes are semipermeable, meaning they have control over what molecules can or cannot pass through. Some molecules can just drift in and out, others require special … WebIf a channel protein exists and is open, the sodium ions will be pulled through the membrane. This movement is used to transport other substances that can attach themselves to the transport protein through the membrane. Many amino acids, as well as glucose, enter a cell this way. how to rob the money truck in jailbreakWebDiffusion can occur across a semipermeable membrane; however diffusion also occurs where no barrier (or membrane) is present.

Webyes. what can you conclude about the diffusion of iodine, glucose, and starch across the selectively permeable dialysis tubing membrane. diffusion occurred based on molecular size. iodine and glucose are much smaller molecules than starch; therefore, they were able to … WebDec 30, 2024 · Higher concentrations of cholesterol, by filling in gaps between phospholipid tails, decreases permeability even for small molecules that can normally pass through the membrane easily. Cells need far more than small nonpolar molecules for their material and energy requirements.

WebIodine is not a gas. It is, however non-polar, and would be able to diffuse through the cell membrane without a terrible amount of trouble. Keep going. Iodine is a solid at room … WebOsmosis is the diffusion of water. And usually you're talking about the diffusion of water as a solvent and usually it's in the context of a semi-permeable membrane, where the actual solute cannot travel through the membrane. Anyway, hopefully you've found that useful and not completely confusing. Up next: video.
