The rate of photosynthetic CO₂ fixation _____ and the rate of the release of CO₂ by photorespiration _______ when _____ a plant is placed in a closed container.

Question

Quizplus · Accepted Answer

When a plant is placed in a closed container, the concentration of CO2 decreases due to its consumption in photosynthesis, leading to a decrease in the rate of photosynthetic CO2 fixation. Simultaneously, the rate of release of CO2 by photorespiration increases because the relative concentration of oxygen inside the container increases as CO2 levels drop, promoting photorespiration over photosynthesis.

The Rate of Photosynthetic CO2 Fixation _____ and the Rate
