The correct answer is: The carbon in carbon dioxide is recycled as glucose.
During photosynthesis, plants use carbon dioxide and water to produce glucose and oxygen. The carbon in carbon dioxide is incorporated into the glucose molecule through a series of biochemical reactions. This glucose can be used as an energy source by the plant or can be broken down to release energy later. Oxygen is also produced and released into the atmosphere as a by-product of photosynthesis.
How do plants recycle carbon during photosynthesis?
• The carbon in glucose is recycled as carbon dioxide.
• The carbon in carbon dioxide is recycled as glucose.
• The carbon in glucose is recycled as carbon gas.
• The carbon in carbon gas is recycled as glucose.
