Electron Transport Chain

Question 1. Name the components of the electron transport chain, mentioning the site of ATP generation & its inhibitors
Answer:

Components of electron transport chain:

• There are five distinct carriers that participate in the electron transport chain
• They are
  1. Nicotinamide nucleotides
  2. Flavoproteins
  3. Iron-sulfur proteins
  4. biochemistry
  5. Coenzyme Q
  6. Cytochromes

Question 2. Mention the reactions where reduced NADP is required
Answer:

Function of electron transport chain

• Reduced NADP is required for the reductive biosynthesis of fatty acids & steroids
• It is used in the synthesis of certain amino acids
• There is a continuous production of hydrogen peroxide in the living cells which can damage unsaturated lipids, proteins & DNA
• This is prevented by antioxidant reactions involving reduced NADP

“Common challenges in mastering electron transport chain notes effectively: FAQs provided”

• Hydroxylation reactions causing detoxification of drugs involve NADPPI
• Phagocytosis requires reduced NADP
• Reduced NADP maintains the concentration of reduced glutathione required to preserve the integrity of the RBC membrane
• It keeps the ferrous iron of hemoglobin in the reduced state
