Which inhibitory outcome arises when high oxygen concentrations compete with carbon dioxide binding to Rubisco?

💡 Explanation

When oxygen competes with carbon dioxide binding to Rubisco, photorespiration occurs because Rubisco acts as an oxygenase, leading to the production of glycolate. Therefore increased glycolate production is the result, rather than altered ATP synthesis, NADPH consumption, or disruption to thylakoid transport, all of which are independent processes.
