David Hopkins Cell Membranes and Transport 1. Explain, using your own words, the fluid mosaic model of the cell membrane. Sketch the different components of the membrane below. 2. Sketch a phospholipid below and label the components. (Should include, Polar head: polar alcohol, phosphate group, glycerol; nonpolar end: hydrophobic tail) Types of Passive/Active Transport Characteristic Simple Diffusion Facilitated Diffusion Active Transport Require ATP? Binding of Transported molecule? With gradient or against gradient of transported molec.? Specificity of transported molecule? Membrane components responsible for transport?

Osmosis/Diffusion problems 1. Here is a cell inside a container of solution. Inside the cell there is 0.5M sucrose and 0.1M fructose. In the solution around the cell there is 0.2Mfructose, 0.1M sucrose, and 0.1M glucose. Please draw these values in below. The cell membrane is permeable to water and glucose only! 1.
