Definitions:

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.

Active Transport

Transport of a substance across a membrane that does not rely on the potential energy of a concentration gradient for the substance being transported and therefore requires an additional energy source (often ATP); includes carrier-mediated active transport, endocytosis, and exocytosis. Compare with diffusion and facilitated diffusion.

Pinocytosis

A cellular process by which cells engulf liquid particles through the formation of small vesicles.
