Question

question 1 - 3
what is the correct equation for cellular respiration?
6o₂ + c₆h₁₂o₆ → 6co₂ + 6h₂o + energy
6o₂ + c₆h₁₂o₆ + energy → 6co₂ + 6h₂o
6co₂ + 6h₂o → 6o₂ + c₆h₁₂o₆ + energy
6co₂ + 6h₂o + energy → 6o₂ + c₆h₁₂o₆

Explanation:

Cellular respiration is a process where glucose (\(C_6H_{12}O_6\)) reacts with oxygen (\(O_2\)) to produce carbon dioxide (\(CO_2\)), water (\(H_2O\)), and energy. The energy is released as a result of breaking down glucose. In the equation, reactants are on the left - hand side and products on the right - hand side.

• For the second option, energy is shown as a reactant which is incorrect as energy is a product in cellular respiration.
• The third and fourth options represent the reverse process (similar to photosynthesis where \(CO_2\) and \(H_2O\) are reactants to produce glucose and \(O_2\) with the help of energy (sunlight)).

Answer:

First option: \(6O_2 + C_6H_{12}O_6
ightarrow6CO_2 + 6H_2O+\text{Energy}\)
