PSS- Sec G- Sec metabolites

Five-carbon isoprene units polymerize to form:

The right choice is B: Terpenes. In PSS- Sec G- 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) Phenolics; C) Alkaloids; D) Lignins. A quick check: if an option needs energy, pumps, or the opposite direction of movement, ask whether that really applies.

PSS- Sec G- Sec metabolites

Volatile terpenes stored in glandular hairs of herbs mainly belong to which classes?

That points to A: Monoterpenes and sesquiterpenes. Compared with the other options, Monoterpenes and sesquiterpenes is the one that correctly describes the PSS- Sec G- Sec metabolites concept. The wrong ones are B) Sesquiterpenes and triterpenes; C) Diterpenes and triterpenes; D) Triterpenes and tetraterpenes. If you’re stuck, eliminate anything that contradicts a basic fact you already know for this topic.

PLANT SEC METABOLITES+PYQS

Monoterpenes contain how many carbons?

Pick B: 10. Thinking through PLANT SEC METABOLITES step by step rules out the lookalikes and leaves 10. Skip these: A) 5; C) 15; D) 20. For hormones and genes, match the molecule or gene to its real role, not a neighboring pathway.

PLANT SEC METABOLITES+PYQS

Which terpene is the longest polymer?

C fits best: Rubber. Keep the PLANT SEC METABOLITES basics straight and Rubber stands out as the precise answer. Avoid: A) Carotene; B) Squalene; D) Dolichol. Light and flowering items often hinge on which photoreceptor or day-length rule is in play.

PLANT SEC METABOLITES+PYQS

The largest class of plant secondary metabolites is:

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

PLANT SEC METABOLITES+PYQS

Terpenes are biosynthesized from which basic unit?

Answer: B) Isoprene (C5H8). For PLANT 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) Acetyl-CoA; C) Phenylalanine; D) Malonate. Name the process first, then pick the option that describes it — don’t reverse cause and effect.
