The renewal edit.
A sealed acidic chamber of digestive enzymes — the cell's controlled recycling facility.
A note
The campaign imagery is a fictional luxury concept. Toggle to Scientific X-Ray for the labelled biological illustration.
Small, spherical organelle surrounded by a single phospholipid bilayer. Contains hydrolytic enzymes, such as proteases, lipases and nucleases, which break down biological macromolecules. Proton pumps in the membrane maintain an acidic internal environment (approximately pH 4.5–5), allowing these enzymes to function effectively.
Intracellular digestion of macromolecules, damaged organelles and materials taken into the cell through endocytosis. Lysosomes also participate in autophagy, the process by which worn-out cellular components are broken down and recycled.
Primarily animal cells and many other eukaryotes. Plant cells generally use lytic vacuoles to perform similar digestive functions.
Lysosomes prevent the accumulation of damaged cellular components and recycle their constituent molecules, such as amino acids and fatty acids, for reuse in cellular metabolism. They also contribute to cellular defence by digesting engulfed pathogens.
The membrane separates digestive enzymes from the cytosol; proton pumps maintain acidic conditions for digestion.

A folded membrane workshop studded with ribosomes — the first address for proteins destined for secretion or the cell's membranes.

A tubular membrane studio devoted to lipids, steroids and detoxification — no ribosomes in sight.
