Question

Quizplus · Accepted Answer

Rubisco has a preference for binding to CO2 (CO₂) rather than oxygen (O₂) during photosynthesis. When CO₂ levels are low, rubisco may mistakenly bind to O₂ instead, resulting in the formation of oxygenated products instead of the desired carbon products. This process, known as photorespiration, can decrease the efficiency of photosynthesis. Therefore, when CO₂ levels are low and O₂ levels are high, rubisco will add O₂ to ribulose 1,5-bisphosphate (RuBP) instead of CO₂, leading to inefficient photosynthesis.
