2015.12.10 CSCS Daily Study Question:
At the end of glycolysis, which metabolic pathway does pyruvate enter if there is insufficient oxygen present?
A) Krebs Cycle
B) Lactic Acid Fermentation
C) Oxidative Phosphorylation
D) Tricarboxylic Acid Cycle
scroll down for answer…..
B) Lactic Acid Fermentation
At the end of the first part of glycolysis, you end up with two molecules of pyruvate (2 pyruvates because the one molecule of 1,6-bisphosphoglycerate gets split into dihydroxyacetone phosphate and glyceraldehyde-3-phosphate, each proceeding through identical pathways). If the body needs energy quickly (faster than oxygen-utilizing energy production methods can produce), then pyruvate is reduced (accepts an electron) by NADH. By NADH giving up an H+, the NAD+ can be used again in the first part of glycolysis.
