Question

Mr. Swerdlow wrote a chemical equation on the board and asked his class what should be changed to make it correct. He wrote:
water + carbon dioxide → glucose + oxygen + energy
What should be changed to show the correct chemical reaction?
1. Carbon dioxide should be traded with glucose, and energy should be shown on both sides.
2. Water should by moved to the products side, and glucose and oxygen should both be moved to the reactants side.
3. Water and carbon dioxide should both be moved to the products side, and glucose and oxygen should be moved to the reactants side.
4. Glucose should be moved to the reactants side, and water and carbon dioxide should both be moved to the products side.

Answer 1

Answer is: 3. Water and carbon dioxide should both be moved to the products side, and glucose and oxygen should be moved to the reactants side.

Balanced chemical reaction for cellular respiration (convert biochemical energy):

C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy, or:

glucose + oxygen → carbon dioxide + water + energy.

This reaction is exothermic (energy is released).

Answer 2

Answer:

The answer is C

Explanation:

   Cellular Respiration: glucose + oxygen    ——>     water + carbon dioxide + energy .    The one that we see is incorrect.  Water and carbon dioxide are products. Glucose and Oxygen are reactants. The Answer C leaves us with the Cellular Respiration formula as it should. ALSO WE ARE NOT TRYING TO MAKE THE EQUATION INTO A PHOTOSYNTHESIS EQUATION!! It is suppose to be a Cellular Respiration equation.
