There are five classes of antibody.
1) <span>IgA (immunoglobin A)
2) IgD (immunoglobin D)
3) IgE (immunoglobin E)
4) IgG (immunoglobin G)
<span>5) IgM (immunoglobin M)
They form Y shaped antibodies. The crystallized fragment is the stalk of the Y shaped antibodies. The bond formed by this stalk will determine the form of the antibody. One Y is called monomer, two connected Ys are called dimers, and 5 connected Ys are called pentamers.</span></span>

Explanation:
The balanced equation for aerobic cellular respiration is: 
C₆H₁₂O₆ + 6 O₂ ----> 6 CO₂ + 6 H₂O + Energy (ATP)
For each glucose molecule that's oxidized, 6 oxygen molecules are used in order to produce ATP. Carbon dioxide and water are byproducts of aerobic respiration..
