Question

What is the main biochemical function of the electron transport chain?

Answer 1

Electron transport chain:

1. It is a set of 4 protein complexes that connect redox processes to create an electrochemical gradient that produces ATP in a process known as oxidative phosphorylation.
2. Its major role is to provide an electrochemical gradient that drives ATP synthesis in chloroplasts and mitochondria during cellular respiration and photosynthesis, respectively.
