Which outcome occurs when photorespiration competitively inhibits carbon fixation during photosynthesis?

💡 Explanation

When photorespiration occurs, rubisco binds oxygen instead of carbon dioxide due to competitive inhibition under high oxygen and temperature, reducing carbon fixation and photosynthetic efficiency. Therefore reduced plant growth results, rather than enhanced chlorophyll, increased nitrogen uptake, or altered root respiration which target different plant functions.
