Q. 18.51 - An Introduction to General, Organic, and Biological Chemistry

Question

According to the chemiosmotic theory, how does the ${\mathrm{H}}^{+}$ gradient provide energy to synthesize $\mathrm{ATP}$?

Step-by-Step Solution

Answer

The ${\mathrm{H}}^{+}$ gradient provides energy to synthesize $\mathrm{ATP}$ by the energy generated during the passing of the hydrogen ions through intermembrane spaces

Step 1: Given information

We need to find the way by which the ${\mathrm{H}}^{+}$ gradient provides energy to synthesize $\mathrm{ATP}$

Step 2: Explanation

When a hydrogen ion crosses across the intermembrane gap through Complex $\mathrm{V}$, it can supply energy to manufacture $\mathrm{ATP}$. Hydrogen ions generate energy in the intermembrane space when they move through Complex $\mathrm{V}$ or $\mathrm{ATP}$ synthase, which is utilized to manufacture $\mathrm{ATP}$ from $\mathrm{ADP}$ and inorganic phosphates.
