Every one of our cells is doing cell respiration to generate enough ATP so that they will have the energy on hand to do the work they need to do.  This means that all of your cells need to absorb monomers, glucose being the most common, in order to fuel cell respiration. Those monomers came from our food, via our digestive system, absorbed into our blood stream and delivered to each cell. We covered this last week, and it is outlined in green.

Cell Membrane Structure and Function

At the cell level, the membrane is controlling the entry of glucose into the cell. In order to understand this process, we will first learn about cell membrane structure and function. We're focusing on the part outlined in red:

Type of molecule Method of crossing the membrane  Why?
small non-polar molecules (O2, CO2, H2O) 
medium sized non-polar molecules (fatty acids)
medium sized polar molecules ( sugar, amino acids, ions like Calcium)
very large molecules (proteins, carbohydrates)
