Which of the following processes does NOT produce carbon dioxide (\(\mathrm{CO_2}\))?

• A. Fermentation in yeast
• B. Combustion of glucose
• C. Cellular respiration in animals
• D. Photosynthesis in plants

Answer: (D)

Verified step by step guidance

1. Step 1: Begin by understanding the processes listed in the problem. Each process involves chemical reactions, and we need to determine whether carbon dioxide (\(\mathrm{CO_2}\)) is produced or not.
2. Step 2: Analyze fermentation in yeast. During alcoholic fermentation, glucose is broken down into ethanol and carbon dioxide (\(\mathrm{CO_2}\)). This process produces \(\mathrm{CO_2}\) as a byproduct.
3. Step 3: Examine the combustion of glucose. Combustion is a chemical reaction where glucose reacts with oxygen to produce carbon dioxide (\(\mathrm{CO_2}\)) and water. This process also releases energy.
4. Step 4: Consider cellular respiration in animals. Cellular respiration involves the breakdown of glucose in the presence of oxygen to produce energy, carbon dioxide (\(\mathrm{CO_2}\)), and water. \(\mathrm{CO_2}\) is released as a waste product.
5. Step 5: Evaluate photosynthesis in plants. Photosynthesis is the process by which plants use sunlight, carbon dioxide (\(\mathrm{CO_2}\)), and water to produce glucose and oxygen. Instead of producing \(\mathrm{CO_2}\), photosynthesis consumes it, making this process the correct answer to the question.
