Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The purpose of the Electron Transport Chain is ____
A
To produce CO2
B
To produce ATP
C
To make glucose
D
To make NADH
Explanation: 

Detailed explanation-1: -The electron transport chain is a series of four protein complexes that couple redox reactions, creating an electrochemical gradient that leads to the creation of ATP in a complete system named oxidative phosphorylation. It occurs in mitochondria in both cellular respiration and photosynthesis.

Detailed explanation-2: -The electron transport chain has two primary functions: it produces a proton gradient-storing energy that can be used to create ATP during chemiosmosis-and generates electron carriers, such as NAD+ and FAD, that are used in glycolysis and the citric acid cycle.

Detailed explanation-3: -To make ATP, energy must be “transported”-first from glucose to NADH, and then somehow passed to ATP. How is this done? With an electron transport chain, the third stage of aerobic respiration. This third stage uses energy to make energy.
