Answer the following questions about the generalized photosynthesis equation:

[tex]\[ 6 \text{CO}_2 + 6 \text{H}_2\text{O} \rightarrow \text{C}_6\text{H}_{12}\text{O}_6 + 6 \text{O}_2 \][/tex]

What are the reactants of photosynthesis? Check all that apply.

- Carbon dioxide
- Glucose
- Oxygen
- Water



Answer :

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.
