What is the function of enzymes in the body?
Enzymes speed up chemical reactions in the body.
Enzymes are only found in plants, not in the body.
Enzymes slow down chemical reactions in the body.
Enzymes have no role in the body.
Give an example of a complex carbohydrate.

What is the difference between saturated and unsaturated fats?
Saturated fats have double bonds between carbon atoms, while unsaturated fats have single bonds.
Saturated fats are liquid at room temperature, while unsaturated fats are solid.
Saturated fats have single bonds between carbon atoms, while unsaturated fats have at least one double bond between carbon atoms.
Saturated fats are healthier than unsaturated fats.

lipid
sugar
amino acid
nucleotide
How do enzymes speed up chemical reactions?
Enzymes change the stoichiometry of reactions.
Enzymes have no effect on chemical reactions.
Enzymes increase the activation energy barrier for reactions.
Enzymes lower the activation energy barrier for reactions.

What is the role of DNA in protein synthesis?
DNA serves as a template for mRNA synthesis, which carries the genetic code from the nucleus to the ribosomes where proteins are synthesized.
DNA is responsible for transporting proteins to the ribosomes
DNA regulates the speed of protein synthesis
DNA acts as a direct source of amino acids for protein synthesis
Which monomer unit after polymerization forms proteins?:
Amino Acid
