Product Description
I created this activity to help students holistically make the connection that in order for our cells to perform protein synthesis, we first need to consume protein as a source of raw materials (amino acids). In this investigation, students examine whether a fictitious serving of white meat and milk will provide enough amino acids to synthesize an actin muscle protein. While the protein molecules in comparison are not structurally representative of the actual molecules in sequence, size, or scale, this lab activity reinforces the principle that cellular protein synthesis is dependent on having us first consume protein. Students count the amino acids ingested in the two servings of protein. Then they transcribe a gene and translate the mRNA to determine the sequence of amino acids in the faux actin protein. Then they count the amino acids required to assemble the actin protein to determine if enough protein was consumed. A page of analysis questions concludes the activity, where students further examine the limits of diffusion, the role of peptide bonds, and the primary factor that determines the sequence of amino acids on a polypeptide chain. Answer keys are provided.
