Q. 18.47 - An Introduction to General, Organic, and Biological Chemistry

Question

How is $\mathrm{NADH}$ oxidized in electron transport?

Step-by-Step Solution

Answer

The $\mathrm{NADH}$ is oxidized in electron transfer as it releases hydrogen ion to form ${\mathrm{NAD}}^{+}$

Step 1: Given information

We need to find out the way by which $\mathrm{NADH}$ is oxidized in electron transfer

Step 2: Explanation

We know that

In Complex $\mathrm{I}$, $\mathrm{NADH}$ is oxidized through electron transfer and hydrogen ion transfer. $\mathrm{NADH}$ is oxidized by losing hydrogen to create ${\mathrm{NAD}}^{+}$, which can be employed in oxidative metabolic pathways such as the citric acid cycle to oxidize substrates.
