#phytochrome interacting factors

3 public questions tagged with this topic.

PHYTOCHROME+PYQS

Phytochrome interacting factors (PIFs) primarily act as:

The right choice is B: Negative regulators of photomorphogenesis. In PHYTOCHROME, that matches how the process or concept actually works — the other choices mix up related ideas or use the wrong mechanism. Skip these: A) Positive regulators of photomorphogenesis; C) Photoreceptors; D) Hormones. A quick check: if an option needs energy, pumps, or the opposite direction of movement, ask whether that really applies.

PSS-Sec-E-Sensory biology

Phytochrome interacting factors are degraded via:

26S proteasome (B) is correct here. This is core PSS-Sec-E-Sensory biology: once you know the definition or pathway step, 26S proteasome is the clear fit. The wrong ones are A) Autophagy; C) Lysosome; D) Vacuole. If the topic is about gradients or potentials, water/solutes move from higher to lower of the relevant quantity.

PSS-Sec-E-Sensory biology

PIFs promote which developmental program in darkness?

Go with B — Skotomorphogenesis. Under PSS-Sec-E-Sensory biology, this is the standard explanation you’d use in class: it names the real driver or definition, while the rest are nearby but wrong. Not these: A) Photomorphogenesis; C) Vernalization; D) Circadian rhythm. When two options sound similar, choose the one that matches the textbook definition most tightly.
