_____ activates transcription of the gene for the small subunit of ______, an enzyme involved in photosynthesis
A) Phytochrome; chlorophyll
B) Chlorophyll; rubisco
C) Phytochrome; rubisco
D) Rubisco; phytochrome
E) Cytochrome; rubisco

Question

Quizplus · Accepted Answer

Phytochrome is a photoreceptor in plants that, upon activation by light, can trigger various developmental processes, including the transcription of genes involved in photosynthesis. Rubisco (ribulose-1,5-bisphosphate carboxylase/oxygenase) is a crucial enzyme in the photosynthetic process, catalyzing the first major step of carbon fixation. Therefore, phytochrome activates the transcription of the gene for the small subunit of rubisco.
