Question

What is the main function of the electron transport chain?

Answer 1

Electron transport chain :

1. The electron transport chain is a sequence of four protein complexes that couple redox reactions, developing an electrochemical gradient that results in the creation of ATP in a system named oxidative phosphorylation.
2. It takes place in mitochondria in both cellular respiration and photosynthesis.
3. The primary function of the electron transport chain is to generate an electrochemical gradient
4. It drives the synthesis of ATP during cellular respiration and photosynthesis in mitochondria and chloroplasts, respectively.
5. It is used in cellular respiration.
6. Cellular respiration is the process that cells use to make energy.
7. Cellular respiration involves three main steps, glycolysis, the citric acid cycle, and oxidative phosphorylation which uses the electron transport chain.
