My guess is that you're wanting the formula for respiration (which is basically the opposite of the formula for photosynthesis)?
So on the left (reactant/inputs) side should be: sugar and oxygen
On the right (products/outputs) side should be:
Carbon dioxide, water, light energy/ATP
Nucleic acids. They contain a phosphate base and a nitrogen group.
Each enzyme is comprised of covalently linked amino acids...enzymes are proteins
Only toms idea could be scientific since it is testable, can be tested by others, have a hypothesis, and be proven
