Question

A lysosome vesicle of 1 µm diameter has an internal pH of 5.0. The total number of H⁺ ions inside this vesicle would range from 

 (A) 10³ to 10⁴ 

 (B) 10⁴ to 10⁵ 

 (C) 10⁵ to 10¹⁰ 

(D) 10¹⁰ to 6.023 × 10²³

Answer 1

Correct option  (A) 10³ to 10⁴

Explanation: 

Lysosome radius is 0.5 μm = 0.5 × 10^–6 m
