Methane is a major component of natural gas, which is used as a fuel in homes. write a balanced equation for the complete oxidation reaction that occurs when methane (ch4) burns in air. use the smallest possible integer coefficients.

Choose an equation that represents an enzyme-catalyzed reaction. (a) enzyme + substrate → enzyme-substrate complex (b) enzyme + substrate ←−→ enzyme + products (c) enzyme + substrate ←−→ enzyme-substrate complex → enzyme + products (d) enzyme + substrate ←−→ enzyme-substrate complex → enzyme-substrate complex + products
