Where are most polymers broken down into monomers?

What reactions are used to break polymers into monomers?

dehydration synthesis

hydrolysis

substitution

redox

What specialized proteins are needed to catalyze these reactions?

enzymes

atp synthase

transporters

Where are most monomers absorbed into the bloodstream?

How are the nutrients (monomers) delivered to cells?

Urine

Blood

Air

Hair

Which substances enter cells from the blood?

Which substances leave cells to the blood?

How are nutrients used for energy?
ATP is the molecule that cells use for energy.
What is the name of the (purple) organelle (small structure inside cells) that makes ATP?

nucleus

Golgi apparatus

mitochondria

lysosome

Which of the monomers can be used by the mitochondrion to produce ATP?

Fatty acids

Monosaccharides

Amino acids

Catabolic reactions are those that break down large molecules in to smaller molecules. Anabolic reactions build larger molecules from small molecules.
When the monomer are used to make ATP, is this catabolism or anabolism?

catabolism

anabolism

Click on "anabolism". Which of the monomers can be made using pyruvate, acetyl-CoA, and intermediates from the citric acid cycle?

Fatty acids

Monosaccharides

Amino acids

Click on "Storage". Which of the molecules are used to store monosaccharides?

Triglycerides (store fatty acids)

Glycogen (stores monosaccharides)

Proteins ("store" amino acids)
