The form of FADH2 is Flavin Adenine Dinucleotide, but it is more accurately described as the reduced form of FAD (Flavin Adenine Dinucleotide).
Here's a breakdown:
- FAD: This is the oxidized form. It can accept two hydrogen atoms (and two electrons) to become FADH2.
- FADH2: This is the reduced form. It has accepted two hydrogen atoms (and two electrons). The '2' signifies that it's the fully reduced state. It carries these electrons to the electron transport chain in cellular respiration.
Essentially, FADH2 is the form of FAD that is carrying energy in the form of electrons. It's a crucial electron carrier in metabolic pathways, particularly in the citric acid cycle (Krebs cycle) and electron transport chain.
