Gce Model Questions Vol1 2024 Biology Question 50
Practice objective / multiple choice question 50 from the 2024 Gce Model Questions Vol1 Biology examination.
In a female mammal, the concentration of follicle‑stimulating hormone (FSH) in the blood follows the equation \(C(t) = C_0 e^{-kt} + \frac{S}{k}\bigl(1 - e^{-kt}\bigr)\) where \(C_0\) is the initial concentration, \(k\) is the clearance rate constant (h^{-1}), and \(S\) is the constant secretion rate (ng·mL^{-1}·h^{-1}). During the early follicular phase, \(C_0 = 5\) ng·mL^{-1}, \(k = 0.2\) h^{-1}, and the pituitary secretion rate rises to \(S = 4\) ng·mL^{-1}·h^{-1}. Calculate the FSH concentration after 12 hours. Give your answer to two decimal places.
