Co-enzymes

Answer 1

• Co-enzymes are non-protein organic molecules that bind to enzymes to assist in catalyzing biochemical reactions.
• In cellular respiration, they act as essential electron and hydrogen carriers during glycolysis and the Krebs cycle.
• Key examples include NAD (Nicotinamide Adenine Dinucleotide) and FAD (Flavin Adenine Dinucleotide).
• During the electron transport chain, $\text{NADH}_2$ and $\text{FADH}_2$ are oxidized, yielding 3 ATP and 2 ATP molecules respectively.
