• Carbohydrate

Which biomolecule is found in fats, oils, and waxes and is a source of long-term energy? 

• Proteins
• Nucleic Acid
• Lipids
• Carbohydrate

Which biomolecule helps form muscles?

• Nucleic Acid
• Carbohydrate

Which biomolecule is responsible for insulation and energy storage?

• Protein
• Nucleic Acid
• Lipid
• Carbohydrate

Which biomolecule determines the traits of organisms (DNA)?

• proteins
• nucleic acids
• carbohydrates
• lipids

What is the purpose  of an enzyme?

• give permission for the reaction
• raise activation energy
• speed up chemical reactions

• control how many reactions occur

Enzymes need certain environmental conditions in order to function properly.  What happens when enzymes are heated to a high temperature?

• they die
• they denature (change shape)
• they change their amino acid sequence
• they work better

Lipids and carbohydrates are similar because they both provide cell with

• energy

• structure

• genetic information

• quick energy

Which of the following is not a function of a lipid?

• Provides insulation for organisms

• A major component of cell membranes

• Provides long term energy storage

• Speeds up chemical reactions
