When we discussed Biological Hierarchy levels, at the bottom, or smallest level, we had subatomic
particles. (COMMAS = cell, organelle, macromolecule, molecule, atom, subatomic particle)
In this video, we see molecules hooking together to form macromolecules. The molecule is an amino
acid or peptide, joining together to form a poplypeptide or protein.
Please answer these questions:
What is the same about each amino acid?
Amino acids linked together form what?
When two amino acids are joined together, what is the name of the reaction?
Why is it called that?
What are the names of the 4 levels of structure in a protein? (Don’t worry if you don’t understand them.
Just start with the names of the structure and we’ll take it from there.)
Mr. Anderson said something about heat, cold, pH change, could do something to the protein. What?
(see 7:35 into the video).
