Blood and their Component

Iron is inserted into protoporphyrin IX by enzyme:

Go with C — Ferrochelatase. Within Blood and their Component, that statement lines up with the standard definition and the usual exam wording you’ll see. In plain terms, Ferrochelatase is the option that correctly names the structure, process, or principle asked for in Blood and their Component. Holding that picture in mind makes Ferrochelatase feel natural rather than something you only memorise. Link the term to a real body example (organ, tissue, or ion flow) so the idea stays concrete under exam pressure. A short mental diagram helps — start from stimulus or structure, follow the pathway, and stop at the functional result described by Ferrochelatase.

Ref: Animal physiology is Unit 7 of the CSIR NET Life Science Syllabus, covering core body systems. It accounts for roughly 10% of the total marks in Sections B and C.

Endocrinology

Conversion of dopamine to norepinephrine requires enzyme:

Go with D — Dopamine β-hydroxylase. Within Endocrinology, that statement lines up with the standard definition and the usual exam wording you’ll see. In plain terms, Dopamine β-hydroxylase is the option that correctly names the structure, process, or principle asked for in Endocrinology. Holding that picture in mind makes Dopamine β-hydroxylase feel natural rather than something you only memorise. Link the term to a real body example (organ, tissue, or ion flow) so the idea stays concrete under exam pressure.

Endocrinology

HbA1c estimation reflects blood glucose level over last:

Pick C: 2–3 months. Thinking about Endocrinology in a practical way — what the structure does, or what the process achieves — leads you here. Clinically and academically, the same logic shows up again and again: 2–3 months is the option that correctly names the structure, process, or principle asked for in Endocrinology. Hence 2–3 months is correct. Treat this as a building block for the rest of Endocrinology; neighbouring topics often reuse the same principle. Keep a one-line summary card for this idea and revisit it before the paper; short, repeated review beats long cramming sessions. If the wording feels dense, translate it into everyday language first, then map that plain sentence back onto 2–3 months.
