🔑 Key Concepts & Definitions

Cell membrane: The semi-permeable phospholipid bilayer that controls substance entry and exit, maintaining the internal environment of the cell.

Nucleus: The organelle containing genetic material and controlling cell activities through regulation of gene expression.

Mitochondria: The powerhouse of the cell responsible for ATP production through aerobic respiration.

Ribosomes: Cellular structures where protein synthesis occurs, translating genetic information into polypeptides.

Endoplasmic reticulum (ER): A network involved in protein and lipid synthesis, divided into rough ER (with ribosomes) and smooth ER (without ribosomes).
