How Do ND1, ND4, and ND6 Contribute to Cellular Respiration?
ND1, ND4, and ND6 genes encode essential proteins that form part of Complex I of the electron transport chain. This complex initiates the process of cellular respiration by oxidizing NADH, which is produced in various metabolic pathways such as the Krebs cycle. The electrons from NADH are transferred through Complex I, which pumps protons across the mitochondrial membrane, generating an electrochemical gradient used to produce ATP, the cell's main energy currency.
