Dr. Ahern pointed out very interesting aspects like heat generation/high energy of PEP and the 2,3-BPG production. Maybe I wasn't paying attention the first time I learned about glycolysis, but this extra integrative information it makes this step easier to remember. Actually, in generally, these human focused biochemistry lectures, are easier to digest, since when I learned it originally, it was mixed with plant and microbial biochem.
