Ten-Step Program?

Standard

The Embden- Meyerhof pathway or as we all call it, glycolysis, is the pathway for acquiring energy from carbohydrates. It is a ten step process and each step is enzyme catalyzed resulting in the production of energy in the form of ATP and NADH (Pratt, 2012).

  • It begins with glucose, a carbohydrate consisting of mainly six carbons.
  • The carb is  oxidized and two (3-carbon) pyruvate.
  • Each metabolized molecule produces two ATP and two NADH molecules.
  • Glycolysis interacts with other pathways of metabolic reactions.
  • During the pathway, other molecules (like glucose-6-phosphate) come in at the 2nd step.(Stoker, 2010)

Three parts, ten steps, and no this isn’t a dance move :|.  Glycolysis is as complicated as it is tear-inducing (well… for those who’ll have to memorize it, anyway).

A few facts:

  • Glycolysis can occur in anaerobic and aerobic conditions.
  • It’s the oldest metabolic pathway known to man.
  • Abnormally high rates may lead to tumor cell formation (the Warburg effect).
  •  Glycolysis is occurs everywhere in the body.
  • It’s responsible for the process of fermentation where yeast is converted into alcohol.

blehhhhhh

With finals right around the corner…  the truth is…

bad time
