NGSS.MS-PS1-2

What is the name of this monomer?

• Monosaccharide
• Triglyceride (Glycerol & Fatty Acids)
• Amino Acids
• Nucleotides

When an enzyme is denatured, what is happening?

• At high temperatures, the shape of the enzyme is altered so it functions better
• At high temperatures, the enzyme changes to a macromolecule
• At high temperatures, the shape of the enzyme is altered so it cannot function properly
• At high temperatures, the enzyme changes to a monomer
