Biochemistry

Using your notes, complete this biochemistry review on lipids, proteins, nucleic acids, and carbohydrates.

Match

Match the following macromolecule to its monomer

• Lipid

• protein

• nucleic acid

• carbohydrate

fatty acid + glycerol

amino acid

nucleotide

monosaccharide

• fatty acid + glycerol

• amino acid

• nucleotide

• monosaccharide

Match

Match the following macromolecule to examples of it

• lipids

• carbohydrates

• proteins

• nucleic acids

cholesterol

wax

starch

glucose

Enzymes

RNA

DNA

• cholesterol

  wax

• starch

  glucose

• Enzymes

• RNA

  DNA

Multiple Choice

Which is solid at room temperature

• Saturated Fatty Acid

• Unsaturated Fatty Acid

Enzymes

Remember, enzymes lower the activation energy of a reaction.

Multiple Choice

Which line did its reaction with an enzyme present?

• green line

• purple line

Multiple Choice

Amylase is a digestive enzyme that breaks starch into monomers (building blocks) of:

• amino acids

• monosaccharide

• glycogen

• nucleotides

Multiple Choice

Which of the following molecules is used as a primary energy source in your body?

• caffeine

• vitamin b

• simple sugar

• amino acid

Proteins

Proteins provide structure for body tissue, hair, and fingernails.

Match

Match the following macromolecule to its main function

• long term energy storage

• structure/tissue growth/enzymes

• quick, rapid energy

• store hereditary (genetic) information

lipid

protein

carbohydrates

nucleic acid

• lipid

• protein

• carbohydrates

• nucleic acid

Multiple Choice

How are the functions of a carbohydrate and a lipid similar?

• both are a source of energy

• both are replicated during meiosis

• both lower the activation energy of reactions

• both dissolve nutrients in the digestive system

Carbs and Lipids

Remember, carbs are for quick energy (primary source). After that runs out, we use lipids for energy (long term)

Multiple Choice

Food provides calories needed by the body for energy. However, the body must use energy between meals when food is not consumed. What is the MOST likely response of the body when more energy is used than calories consumed provide?

• to increase blood flow to the limbs for energy production

• to release energy from lipids stored throughout the body

• to transform stored proteins into carbohydrates for energy

• to contract muscles to create heat energy for the body
