The two categories of protein are:

• Animal and Plant; Animal: Meat, Eggs; Plant: Beans, Lentils

• Complete and Incomplete; Complete: Meat, Eggs; Incomplete: Beans, Lentils

• Essential and Non-Essential; Essential: Meat, Eggs; Non-Essential: Beans, Lentils

• Structural and Functional; Structural: Meat, Eggs; Functional: Beans, Lentils

Amino acids are the building blocks of what?

• Proteins

• Carbohydrates

• Lipids

• Nucleic acids

Amino acids are linked together by which type of bond?

• Ionic bond

• Hydrogen bond

• Peptide bond

• Covalent bond

There are ___ amino acids in total, and your body makes ___ nonessential amino acids.

• 20, 11

• 22, 9

• 18, 10

• 21, 12

Which types of proteins have all essential amino acids?

• Complete proteins

• Incomplete proteins

• Non-essential proteins

• All proteins

A protein's shape is determined by:

• The sequence of amino acids

• The temperature of the environment

• The pH level of the solution

• The presence of water molecules

Hydrogen bonds are important in amino acid chains because they:

• stabilize the secondary structure of proteins

• provide energy for metabolic reactions

• act as catalysts in biochemical reactions

• form the primary structure of proteins

Denaturation is:

• a process that involves the alteration of a protein's natural structure

• the synthesis of proteins from amino acids

• the breakdown of proteins into amino acids

• the replication of DNA
