Definitions:

Glycolysis

The metabolic pathway that breaks down glucose to pyruvate, releasing energy and forming ATP, occurring in the cytoplasm of cells.

Basal Bodies

Microtubule-organizing centers found at the base of cilia or flagella in eukaryotic cells, crucial for their growth and function.

Mitochondria

Organelles found in the cytoplasm of eukaryotic cells that produce energy through cellular respiration, often referred to as the powerhouses of the cell.

Hydrolytic Enzymes

Enzymes that catalyze the cleavage of bonds in molecules through the addition of water.
