Attempts to genetically modify rubisco to help increase food production might include trying to ________.
A)enhance the carboxylation reaction and suppress the oxygenation reaction
B)suppress the carboxylation reaction and enhance the oxygenation reaction
C)decrease the value of kcat by site-directed mutagenesis
D)increase rubisco's activity in the dark

Question

Quizplus · Accepted Answer

Rubisco has a low efficiency in fixing carbon dioxide, and it also competes with oxygen for the active site, which is a side reaction that reduces carbon fixation efficiency. Enhancing the carboxylation reaction and suppressing the oxygenation reaction is a viable strategy to increase carbon fixation and overall plant growth.
