Which of the following correctly identifies the inputs and outputs of the photosynthesis equation?\(6\text{CO}_2 + 6\text{H}_2\text{O} + \text{light energy} \rightarrow \text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2\)
A
Inputs: \(\text{CO}_2\), \(\text{O}_2\), light energy; Outputs: \(\text{H}_2\text{O}\), \(\text{C}_6\text{H}_{12}\text{O}_6\)
B
Inputs: \(\text{CO}_2\), \(\text{H}_2\text{O}\), light energy; Outputs: \(\text{C}_6\text{H}_{12}\text{O}_6\), \(\text{O}_2\)
C
Inputs: \(\text{O}_2\), \(\text{H}_2\text{O}\); Outputs: \(\text{CO}_2\), \(\text{C}_6\text{H}_{12}\text{O}_6\)
D
Inputs: \(\text{C}_6\text{H}_{12}\text{O}_6\), \(\text{O}_2\); Outputs: \(\text{CO}_2\), \(\text{H}_2\text{O}\), light energy
Verified step by step guidance1
Step 1: Begin by recalling the overall chemical equation for photosynthesis: \(6\text{CO}_2 + 6\text{H}_2\text{O} + \text{light energy} \rightarrow \text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2\). This equation represents the process by which plants convert carbon dioxide, water, and light energy into glucose and oxygen.
Step 2: Identify the inputs (reactants) in the photosynthesis equation. These are the substances that are consumed during the reaction. From the equation, the inputs are \(\text{CO}_2\) (carbon dioxide), \(\text{H}_2\text{O}\) (water), and light energy.
Step 3: Identify the outputs (products) in the photosynthesis equation. These are the substances that are produced during the reaction. From the equation, the outputs are \(\text{C}_6\text{H}_{12}\text{O}_6\) (glucose) and \(\text{O}_2\) (oxygen).
Step 4: Compare the given answer choices to the correct identification of inputs and outputs. The correct answer should match the inputs (\(\text{CO}_2\), \(\text{H}_2\text{O}\), light energy) and outputs (\(\text{C}_6\text{H}_{12}\text{O}_6\), \(\text{O}_2\)).
Step 5: Eliminate incorrect answer choices by checking if they misidentify the inputs or outputs. For example, \(\text{O}_2\) is not an input, and \(\text{H}_2\text{O}\) is not an output in photosynthesis. Select the answer that correctly matches the equation.
