arlik [135]

The true statements about oxidative phosphorylation are the mechanisms of phosphorylation and oxidation are directly coupled.

<h3>What is oxidative phosphorylation ?</h3>
  • An electron transfer chain that is fueled by substrate oxidation and connected to ATP generation via an electrochemical transmembrane gradient is known as oxidative phosphorylation (OXPHOS).
  • Cells employ enzymes to oxidize foods in the metabolic process known as oxidative phosphorylation, electron transport-linked phosphorylation, or terminal oxidation, which releases chemical energy to create adenosine triphosphate. This happens inside mitochondria in eukaryotes.

Steps in Oxidative Phosphorylation

  • Electron Transport using NADH and FADH2. Near the start of the transport chain, reduced NADH and FADH2 transmit their electrons to molecules. ... the splitting of oxygen into water, proton pumping, electron transport, and ATP synthesis.
