Phosphate

A chemical compound containing the phosphate ion, PO4^3-, crucial for energy transfer in biological systems and a key component of nucleic acids and cellular membranes.

Glucose Metabolism

Biochemical processes responsible for the generation of energy and metabolic precursors from glucose.

Compare with diffusion and facilitated diffusion.
