Passive transport is the movement of substances across the membrane without any input of energy by the cell active transport is the movement of materials where a cell is required to expend energy in the case of this lab the discussion will be centered on passive transport. Lab #3 - membrane transport lecture notes in today’s experiments we will explore membrane transport processes, focusing on passive transport, specifically diffusion of molecules through various types of matter and across semipermeable membranes.
For this lab, the focus was on passive transport, specifically the passive process of osmosis osmosis is a form of diffusion diffusion refers to the random movement of solute particles across the cell membrane. Transport of such molecules and ions across all cellular membranes is mediated by transport proteins associated with the underlying bilayer because different cell types require different mixtures of low-molecular-weight compounds, the plasma membrane of each cell type contains a specific set of transport proteins that allow only certain ions . Water lab report - water is a charged or polar molecule (h+ - o- - h+) that is always moving across cell membranes scientists theorize that this is possible because it is such a small molecule or because there are special gap or pores that allow water movement through the cell membrane.
