WebMar 26, 2024 · When each side of a membrane has equal solute concentration, the solution is said to be isotonic and water molecules will be equally likely to move in both directions across the membrane. In the case of a hypertonic solution, there is more solute outside the cell than inside the cell. Hypertonic solutions cause water molecules to move out of the … WebAll substances that move through the membrane do so by one of two general methods, which are categorized based on whether or not energy is required.

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. Webacross the membrane when it is so big? (Think what provides the energy to move it). Expert Answer Relation between hydrogen pump and sucrose transport : If sucrose molecules follow apoplastic pathway, the transfer cells or modified companion cells pump out hydrogen ions into the cell wall from cytoplasm through the proton pumps, which is … WebMar 6, 2024 · A protein involved in moving only one molecule across a membrane is called a uniport (Figure 3.25). Proteins that move two molecules in the same direction across the membrane are called symports (also called synporters, synports, or symporters).
