Question

question①
how are combustion and cellular respiration similar?
answer
at the end of both chemical reactions, carbon dioxide and water are produced.
both have octane and oxygen as reactants of the chemical reactions.
neither give off heat as a by - product.
both have glucose and oxygen as reactants of the chemical reactions.
i dont know yet

Explanation:

Combustion is a chemical - reaction of a substance with oxygen, releasing heat and light. Cellular respiration is the process by which cells break down glucose in the presence of oxygen to produce carbon dioxide, water, and energy (in the form of ATP). Both processes result in the production of carbon dioxide and water as end - products. Octane is a reactant in gasoline combustion but not in cellular respiration. Both processes release heat. Glucose is a reactant in cellular respiration but not in general combustion of non - organic substances like octane.

Answer:

At the end of both chemical reactions, carbon dioxide and water are produced.
