Answer:
Any given experiment has numerous control variables, and it's important for a scientist to try to hold all variables constant except for the independent variable. If a control variable changes during an experiment, it may invalidate the correlation between the dependent and independent variables.
Explanation:
During anaerobic oxidation of a glucose molecule 2 ATP molecules are gained as the net profit. It is because here is no Krebs cycle and electron transport chain in anaerobic respiration.
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
Water molecules would probably be it since they are in water and they are made up of two hydrogen and one oxygen.
