One record opens the network.
Glycolysis
The ten-step cytosolic pathway that splits one glucose into two pyruvate, with a net gain of 2 ATP and 2 NADH.
DNA
A double-stranded molecule whose sequence stores and passes on hereditary information in most cells.
Photosynthesis
The capture of light energy and transfer of carbon from carbon dioxide into organic molecules by plants, algae, and some bacteria.
Insulin Signaling
How insulin receptor signaling coordinates glucose uptake and nutrient storage.
TP53
A protein-coding gene whose product helps cells respond to stress by regulating cell-cycle arrest, DNA repair, senescence, and apoptosis.
Cellular Respiration
How cells transfer energy from fuel molecules into ATP, often using oxygen in the final electron-accepting step.
