When a protein unfolds, it is

• Denatured
• Building
• Adding amino acids
• Making food

Each amino acid is different from the other due to....

• The R group
• The amino group
• The carboxyl group
• The central carbon

Cells must produce many different enzymes because

• enzymes are quickly used up
• most cellular reactions require a specific, unique enzyme
• They have to have some way to use up the protein that they consume
• enzymes are not very effective at speeding up reactions

The polymer which folds into proteins

• Polypeptide
• Amino Acids
• Nucleic Acids
• Polynucleotides
