Question

question: which of the following correctly summarizes photosynthesis? answer options: select one of four carbon monoxide and glucose are used; water is created. carbon dioxide, water, and glucose are used; oxygen is created. glucose and oxygen are used; carbon dioxide and water are created. carbon dioxide and water are used; glucose and oxygen are created.

Explanation:

Photosynthesis is the process by which plants use carbon dioxide ($\ce{CO_2}$) and water ($\ce{H_2O}$) in the presence of light energy to produce glucose ($\ce{C_6H_{12}O_6}$) and oxygen ($\ce{O_2}$). Let's analyze each option:

• First option: Carbon monoxide is not a reactant in photosynthesis, and glucose is a product, not a reactant. So this is incorrect.
• Second option: Glucose is a product, not a reactant in photosynthesis. So this is incorrect.
• Third option: This describes cellular respiration (using glucose and oxygen to produce carbon dioxide and water), not photosynthesis. So this is incorrect.
• Fourth option: Matches the reactants (carbon dioxide and water) and products (glucose and oxygen) of photosynthesis.

Answer:

The correct option is: Carbon dioxide and water are used; glucose and oxygen are created.
