Has Glycolysis Changed in 50 Years? Comparing a 1974 Biochemistry Textbook with Modern Biochemistry
A 1974 biochemistry textbook shows a glycolytic pathway remarkably similar to the one taught today—but it also reports 38 ATP per glucose. What changed in 50 years, and what stayed the same?
Why RPM Alone Is Not Enough: RCF, ×g, and Reproducible Centrifugation
Learn the difference between RPM and RCF (×g), why rotor radius matters, how to convert centrifuge speed correctly, and why reporting RPM alone can reduce experimental reproducibility.
