How redox reactions drive bacteria's Na⁺-NQR sodium pump

The enzyme Na⁺-NQR is a sodium pump that drives the respiration of many marine and pathogenic bacteria. Using redox reactions, the process of exchanging electrons between materials, it powers the transportation of sodium ions across the membrane, supporting the growth of the

Trump to undo legal basis for US climate rules
