Endocrine System Questions and Answers PDF Questions
Question 1 of 5
Which of the following are a group of lipid-soluble hormones derived from cholesterol?
Correct Answer: A
Rationale: Steroid hormones, derived from cholesterol, are lipid-soluble, enabling membrane crossing e.g., cortisol, testosterone. Peptide hormones (e.g., insulin) are water-soluble, amines (e.g., adrenaline) from tyrosine not cholesterol. The question's cutoff omits options, but 'steroid hormones' aligns with endocrine science and prior answer 'C' (likely misaligned OCR). This cholesterol origin distinguishes steroids' synthesis and action, crucial for their role in stress, reproduction, and metabolism, unlike protein-based hormones.
Question 2 of 5
Which of the following hormones promotes increases in the basal metabolic rate (BMR)?
Correct Answer: D
Rationale: Thyroid hormones (T3/T4) elevate BMR by accelerating cellular metabolism, unlike insulin (glucose storage), ACTH (cortisol trigger), or glucagon (glucose release). 'D' inferred from context. This distinguishes thyroid's systemic energy role, critical for thermoregulation, contrasting with acute metabolic regulators.
