Our cells are like a house
In this picture, each cell is a house on a street. The body keeps many houses running at once, with crews that check parcels, clear waste, and keep the lights steady.
- Alert guards (ABC transporters): sentries that manage what comes in and goes out.
- Steady power (mitochondria): the basement generator that keeps energy flowing.
- Efficient recycling (lysosomes): a closed loop that processes cellular waste without leakage.
