These enzymes are proteins. The transport of molecules. Generation and transmission of nerve impulses. Control of growth and differentiation. Another stain, Coomassie blue can also be used.
Cells unfortunately contain thousands of different proteins.
Electrophoresis will separate protein based on the migration of charged particles in an electric field. This procedure uses a polyacrylamide gel which acts like a sieve to slow proteins based upon their molecular weight. The heavier the molecular weight the shorter path it will travel, the lighter the molecular weight the longer path it will travel. The information from the sixth grade Life Science curriculum on foods will be incorporated into the seventh grade Physical Science unit. There will be a two-step approach.
