To determine the reactants of photosynthesis, let's analyze the given photosynthesis equation:
[tex]\[
6 CO_2 + 6 H_2O \rightarrow C_6H_{12}O_6 + 6 O_2
\][/tex]
In a chemical equation, the substances on the left side of the arrow (→) are the reactants, as they are the starting materials that undergo a reaction. The substances on the right side of the arrow are the products, which are formed as a result of the reaction.
Let's identify each component in the given equation:
1. Left Side - Reactants:
- 6 CO_2: This represents six molecules of carbon dioxide.
- 6 H_2O: This represents six molecules of water.
2. Right Side - Products:
- C_6H_{12}O_6: This represents one molecule of glucose.
- 6 O_2: This represents six molecules of oxygen.
Based on this analysis, the reactants of photosynthesis are:
- Carbon dioxide ([tex]\(CO_2\)[/tex])
- Water ([tex]\(H_2O\)[/tex])
Given the options provided:
- carbon dioxide: Yes, this is a reactant.
- glucose: No, this is a product.
- oxygen: No, this is a product.
- water: Yes, this is a reactant.
Thus, the correct reactants of photosynthesis are carbon dioxide and water.
