Each enzyme produced by the body is
open - meaning it is able to catalyze a reaction with any molecule.
immature - meaning it cannot catalyze a reaction until many years later.
incomplete - meaning it requires other parts before it is able to bind to a molecule.
specific - meaning it is only able to catalyze a rection with a certain molecule.

Why does a plant have both chloroplast and mitochondria?
The chloroplast makes glucose that the mitochondria uses to make ATP.
Photosynthesis can not produce ATP
When its dark photosynthesis stops and the mitochondria produces glucose
