Large Biological Molecules

Why is information about carbon critical to understanding the "Molecules of Life"?

• It is the backbone of biological molecules required for life

• It is the only element that can form triple bonds

• It results in the theory of vitalism (organic molecules are produced only in living organisms)

• It is able to cause dehydration

4 Why are fossil fuels, such as gasoline, considered organic compounds?

• they contain both hydrogen and carbon

• they contain hydrogen

• they contain carbon

• they are only produced from living organisms

There are two forms of hydrocarbons. Which is most able to accept new atoms and why?

• saturated hydrocarbons; they have double or triple bonds that can be broken B

• saturated hydrocarbon; they have single bonds only which are easier to break
