Question

How do cells get ATP, the energy currency that does work in living things?

It evolves via chemical evolution.

It passes through the cell membrane.

Answer 1

How do cells get ATP through Cellular Respiration.
Cellular respiration takes place in the mitochondria. The Mitochondria use oxygen (O2) to convert broken-down glucose (at type of sugar) into carbon dioxide (CO2) and water (H2O).
The reactants of CR are oxygen and glucose.
The products of CR are ATP, carbon dioxide, and water.
