What Is a Cell?
A beginner-friendly introduction to the smallest unit that can carry out life processes.
Starts the Cells and Organelles series
The compartments and architecture of life at the cellular scale.
This topic is part of the long-term MOLBIO taxonomy and is visible now so the learning map stays honest. The hub is live, but the dedicated lesson set is still being built.
Lightweight learning path
This hub will connect the molecular lessons to the spaces inside cells where those events take place.

Cellular respiration
Cell BiologyThe process cells use to extract energy from food molecules and make ATP.
Cristae
Cell BiologyThe folded inner membrane structures of mitochondria that increase surface area for energy production.
Cell membrane
Cell BiologyThe thin lipid layer that surrounds a cell and controls what enters and leaves.
Cytoplasm
Cell BiologyThe gel-like fluid inside a cell where many reactions take place.
Mitochondrion
Cell BiologyThe organelle that produces most of a cell's usable energy as ATP.
