Biochem

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.

Enzymes are a type of which macromolecule?

• carbohydrate

• lipid

• protein

• nucleic acid

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

• Chloroplasts are found in the roots of the plant and mitochondria is found in the leaves.
