Question 1 of 5
The hormone that stimulates testosterone secretion is
Correct Answer: B
Rationale: Luteinizing hormone (LH) from the anterior pituitary stimulates testosterone production in testicular Leydig cells. 'Luteinising hormone,' is correct, per endocrinology texts like Guyton, driving male reproductive function. 'Follicle stimulating hormone,' targets spermatogenesis. 'Prolactin,' affects lactation, not testosterone. 'Oxytocin,' aids labor, not hormone secretion. LH's specific role in testosterone synthesis makes B the accurate answer, key to the hypothalamic-pituitary-gonadal axis.
Question 2 of 5
The enzyme that digests carbohydrates in the mouth is
Correct Answer: B
Rationale: Amylase (salivary amylase or ptyalin) begins carbohydrate digestion in the mouth, breaking starches into maltose. 'Amylase,' is correct, per biochemistry (e.g., Lehninger). 'Lipase,' digests fats, mainly in the intestine. 'Protease,' targets proteins. 'Pepsin,' is gastric, for proteins. Amylase's oral action makes B the precise answer.
