3 public questions tagged with this topic.

Dephosphorylation of phototropin in darkness is mediated by:

C fits best: Protein phosphatase 2A. Keep the Phototropin+All basics straight and Protein phosphatase 2A stands out as the precise answer. Avoid: A) Kinase; B) Proteasome; D) COP1. Light and flowering items often hinge on which photoreceptor or day-length rule is in play.

PHOT2 is mainly required for phototropism under:

B fits best: High light. Keep the Phototropin+All basics straight and High light stands out as the precise answer. Avoid: A) Low light; C) Red light; D) Darkness. Light and flowering items often hinge on which photoreceptor or day-length rule is in play.

Cryptochrome functions mainly in regulation of:

Photomorphogenesis (B) is correct here. This is core cryptochrome: once you know the definition or pathway step, Photomorphogenesis is the clear fit. The wrong ones are A) Photosynthesis; C) Respiration; D) Transpiration. If the topic is about gradients or potentials, water/solutes move from higher to lower of the relevant quantity.
