PSS- Sec G- Sec metabolites

Plants with high cyanogenic glycosides but pathogen susceptibility indicate pathogen has:

Answer: C) Cyanide-resistant oxidase. For PSS- Sec G- Sec metabolites, remember the key idea and you’ll land on this option; the distractors usually swap cause and effect or confuse similar terms. Avoid: A) Low respiration; B) High β-glucosidase; D) Low toxin uptake. Name the process first, then pick the option that describes it — don’t reverse cause and effect.

PSS- Sec G- Sec metabolites

Which enzyme converts cyanogenic glycosides into toxic products in herbivores?

That points to B: β-glucosidase. Compared with the other options, β-glucosidase is the one that correctly describes the PSS- Sec G- Sec metabolites concept. The wrong ones are A) ACC oxidase; C) Peroxidase; D) Catalase. If you’re stuck, eliminate anything that contradicts a basic fact you already know for this topic.

PSS- Sec G- Sec metabolites

Cyanogenic glycosides release which toxic compound?

Correct option is C, HCN. In PSS- Sec G- Sec metabolites problems like this, the accurate statement is HCN; the others are common mix-ups. Not these: A) CO2; B) NH3; D) SO2. Tissue transport questions usually turn on xylem vs phloem, living vs dead cells, or source vs sink.

PLANT SEC METABOLITES+PYQS

Dhurrin occurs in:

The right choice is B: Sorghum. In PLANT SEC METABOLITES, that matches how the process or concept actually works — the other choices mix up related ideas or use the wrong mechanism. Skip these: A) Cassava; C) Potato; D) Rice. A quick check: if an option needs energy, pumps, or the opposite direction of movement, ask whether that really applies.

PLANT SEC METABOLITES+PYQS

Cyanogenic glycosides release:

HCN (C) is correct here. This is core PLANT SEC METABOLITES: once you know the definition or pathway step, HCN is the clear fit. The wrong ones are A) NH3; B) CO2; D) SO2. If the topic is about gradients or potentials, water/solutes move from higher to lower of the relevant quantity.
