Integral Proteins

Our video takes the viewer on an educational journey about integral proteins. The structure of a phospholipid includes a hydrophillic, or water loving, phosphate head and several phosphate tails. One of the phosphate tails is saturated and the other one is unsaturated. Both of these tails are hydrophobic or water hating. The phospholipid bilayer is one of three ways phospholipids are arranged. Integral proteins are embedded within the bilayer allowing for active and passive transport. While active transport pushes a substance against the concentration gradient, passive transport allows a substance to move with the concentration gradient. It is active transport that requires Adenosine Triphosphate or ATP. Integral proteins are responsible for metabolic processes such as glycolysis, photosynthesis and aerobic metabolism. These metabolic processes allow for an internal balance known as homeostasis.

I like how you acted out the bilayer. The tails are hydrocarbons, not phosphate. Just a technicality: the proteins actually stick out from either side of the membrane. They're embedded but part of them sticks out. It would have been interesting for you to explain just a bit more what you meant by "concentration gradient." PS Integral proteins are also vital to photosynthesis (and millions of other functions). (-:
