A plant leaf cell membrane has a permeability coefficient for glucose of \(1.2\times10^{-5}\) cm s⁻¹. The glucose concentration inside the cell is \(0.15\) mol cm⁻³ and outside it is \(0.05\) mol cm⁻³. If the membrane surface area is \(2.5\times10^{-3}\) cm², calculate the rate of glucose transport across the membrane in mol s⁻¹ using the equation \(J = P \times A \times (C_{inside} - C_{outside})\).

Answer Options

A. 2.0×10⁻⁹ mol s⁻¹
B. 3.0×10⁻⁸ mol s⁻¹
Correct Answer C. 3.0×10⁻⁹ mol s⁻¹
D. 1.5×10⁻⁹ mol s⁻¹
Correct Answer
C
Correct Option:
3.0×10⁻⁹ mol s⁻¹
