1.

The pentose phosphate pathway is an important metabolic pathway within cells that allows them to synthesize two essential products. What are these two products, and what do they do?

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.

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

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

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.

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