In the above experiment, chloroplasts were isolated from plants grown at different light intensities. The mutant plants produced more chlorophyll b . The scientists predicted the mutant plants would grow better in any light intensity; why might this be?

Faster production of ATP and reduced NADP.

Less RuBP recycled.

Faster production of ATP and NADP+
