Which outcome occurs when increasing atmospheric carbon dioxide concentration inhibits photorespiration in C3 plants?

💡 Explanation

When atmospheric CO2 increases and inhibits photorespiration, Rubisco will favor carboxylation over oxygenation during initial carbon-fixation in, increasing the carbon-fixation rates. Therefore C3 cycle rate of carbon fixation accelerates, because greater concentration reduces inefficiency, rather than alternatives which would require different pathways.
