Explain how amino acid sequence data can help scientists infer patterns of evolutionary relationships between species. ... A gene's DNA sequence determines the order of amino acids that make up a protein, so changes in the DNA sequence often result in changes in the amino acid sequence as well.
The role of NADH and FADH2 is to donate electrons to the electron transport chain. They both donate electrons by providing an hydrogen molecule to the oxygen molecule to create water during the electron transport chain. NADH is a product of both the glycolysis and Kreb cycles. FADH2 is only produced in Krebs cycle.
