Major Organelles and Their Functions

Nucleus -storage and regulation of genetic information.

Cytoplasm - maintaining cell structure.

Mitochondria - energy production (ATP), oxidative phosphorylation and the Krebs cycle.

Endoplasmic Reticulum (ER) - protein and lipid synthesis.

Golgi Apparatus - modification, sorting, and transportation of proteins and lipids.

Lysosomes|Peroxisomes - digestion of cellular waste|detoxification and lipid metabolism.

Ribosomes - protein synthesis on ribosomes.

Cytoskeleton - Microtubules, actin filaments, and intermediate filaments. Maintaining cell shape and intracellular transport.
