Proteins

Enyzmes are a very important type of protein used to

• Build bones in skeleton
• Send hormonal signals throughout body
• Speed up chemical reactions
• Photosynthesize glucose in plants

What is a peptide bond?

• Bond that holds two amino acids together.
• A bond that holds hydrogen and oxygen molecules together.
• A bond that holds the phosphate group of one nucleotide and a sugar of a neighboring nucleotide.
• A bond that is formed by the sharing of electrons.

What is a protein: 

• A polymer composed of many sugars.
• A polymer composed of many amino acids. 
• A polymer composed of fatty acids. 
• A polymer composed of nucleotides. 

What is the monomer of proteins?

• amino acids
