5 public questions tagged with this topic.

Ethylene receptors function as:

Pick B: Negative regulators. Thinking through Phytohormone ALL step by step rules out the lookalikes and leaves Negative regulators. Skip these: A) Positive regulators; C) Transcription factors; D) Ion channels. For hormones and genes, match the molecule or gene to its real role, not a neighboring pathway.

Ethylene triple response includes all except:

Go with D — Increased elongation. Under Phytohormone ALL, 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) Reduced elongation; B) Radial swelling; C) Tight apical hook. When two options sound similar, choose the one that matches the textbook definition most tightly.

EBF1 and EBF2 proteins function in:

EIN3 degradation (C) is correct here. This is core Ethylene: once you know the definition or pathway step, EIN3 degradation is the clear fit. The wrong ones are A) Ethylene synthesis; B) Ethylene perception; D) ACC formation. If the topic is about gradients or potentials, water/solutes move from higher to lower of the relevant quantity.

EIN3 functions as:

Go with C — Transcription factor. Under Ethylene, 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) Kinase; B) Receptor; D) Transporter. When two options sound similar, choose the one that matches the textbook definition most tightly.

EIN2 is localized to:

Correct option is C, ER membrane. In Ethylene problems like this, the accurate statement is ER membrane; the others are common mix-ups. Not these: A) Nucleus; B) Cytosol; D) Chloroplast. Tissue transport questions usually turn on xylem vs phloem, living vs dead cells, or source vs sink.
