Which of the following is a key structural component involved in the electron transport chain in organic chemistry reactions?
A
Cytochrome c
B
NADPH
C
FADH2
D
ATP synthase
Verified step by step guidance1
Understand the context: The electron transport chain is a series of complexes that transfer electrons from electron donors to electron acceptors via redox reactions, and couples this electron transfer with the transfer of protons across a membrane.
Identify the key components: In the electron transport chain, several molecules play crucial roles, including cytochromes, NADH, FADH2, and ATP synthase.
Focus on cytochromes: Cytochromes are proteins that contain heme groups and are involved in electron transport. Cytochrome c is a small heme protein associated with the inner membrane of the mitochondria and plays a key role in the electron transport chain.
Differentiate between the options: NADPH is primarily involved in anabolic reactions and is not directly part of the electron transport chain. FADH2 is a coenzyme that donates electrons to the electron transport chain, but it is not a structural component. ATP synthase is involved in the production of ATP, but not directly in electron transport.
Conclude with the key structural component: Cytochrome c is the correct answer as it is a key structural component involved in the electron transport chain, facilitating the transfer of electrons between complexes.
