Biochemistry Question of the Day

NADPH, which is used in reductive biosynthesis reactions, and Ribose-5-Phosphate, which is used as a major precursor to generate nucleotides

NADH and FADH2, both of which are used to generate ATP in the cell via oxidative phosphorylation

Glutathione, which helps to maintain a reducing environment inside of cells, and 2,3-bisphosphoglycerate, which helps to reduce hemoglobin's affinity for O2.

Fructose-2,6-bisphosphate, which plays a major regulatory role in glycolysis and gluconeogenesis, and glycerol-3-phosphate, which plays a role in the synthesis of triglycerides and phospholipids.

Acetoacetate and beta-hydroxybutyrate, both of which are ketone bodies that serve as a fuel source for cells in the body when blood levels of glucose are low.
