Answer :
To determine the reactants in the chemical equation for cellular respiration, we need to analyze the equation itself. The chemical equation for cellular respiration is:
[tex]\[ \text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2 \rightarrow 6\text{CO}_2 + 6\text{H}_2\text{O} + \text{energy} \][/tex]
From this equation, we can identify the substances that are present before the arrow (reactants) and the substances that are produced after the arrow (products). Reactants are the substances that undergo a chemical change, while products are the substances that are formed as a result of the reaction.
In the given chemical equation:
- On the left-hand side of the arrow, we see the reactants.
- [tex]\(\text{C}_6\text{H}_{12}\text{O}_6\)[/tex] (glucose)
- [tex]\(6\text{O}_2\)[/tex] (oxygen)
According to this equation, the reactants are [tex]\( \text{C}_6\text{H}_{12}\text{O}_6 \)[/tex] (glucose) and [tex]\( 6\text{O}_2 \)[/tex] (oxygen).
Now let's match these with the given options:
- (a) 6O2 (oxygen) - Correct, [tex]\( 6\text{O}_2 \)[/tex] is a reactant.
- (b) Оь - This seems to be a typographical error and does not correspond to any reactants or products in the equation.
- (c) 6CO2 (carbon dioxide) - Incorrect, [tex]\( 6\text{CO}_2 \)[/tex] is a product.
- (d) H2O (water) - Incorrect, [tex]\( 6\text{H}_2\text{O} \)[/tex] is a product.
- (e) C6H12O6 (glucose) - Correct, [tex]\( \text{C}_6\text{H}_{12}\text{O}_6 \)[/tex] is a reactant.
Thus, the correct answers are:
- 6O2
- C6H12O6
[tex]\[ \text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2 \rightarrow 6\text{CO}_2 + 6\text{H}_2\text{O} + \text{energy} \][/tex]
From this equation, we can identify the substances that are present before the arrow (reactants) and the substances that are produced after the arrow (products). Reactants are the substances that undergo a chemical change, while products are the substances that are formed as a result of the reaction.
In the given chemical equation:

- [tex]\(\text{C}_6\text{H}_{12}\text{O}_6\)[/tex] (glucose)
- [tex]\(6\text{O}_2\)[/tex] (oxygen)
According to this equation, the reactants are [tex]\( \text{C}_6\text{H}_{12}\text{O}_6 \)[/tex] (glucose) and [tex]\( 6\text{O}_2 \)[/tex] (oxygen).
Now let's match these with the given options:
- (a) 6O2 (oxygen) - Correct, [tex]\( 6\text{O}_2 \)[/tex] is a reactant.
- (b) Оь - This seems to be a typographical error and does not correspond to any reactants or products in the equation.
- (c) 6CO2 (carbon dioxide) - Incorrect, [tex]\( 6\text{CO}_2 \)[/tex] is a product.
- (d) H2O (water) - Incorrect, [tex]\( 6\text{H}_2\text{O} \)[/tex] is a product.
- (e) C6H12O6 (glucose) - Correct, [tex]\( \text{C}_6\text{H}_{12}\text{O}_6 \)[/tex] is a reactant.
Thus, the correct answers are:
- 6O2
- C6H12O6
