1. How are the endergonic reactions of the first phase of glycolysis coupled to the hydrolysis of ATP, whichis exergonic? How are the exergonic reactions of the second phaseof glycolysis coupled to the endergonic synthesis of ATP and NADH?

2. In what ways is the inner mitochondrialmembrane essential to the coupling of electron transport and ATP synthesis? Could the membrane carry out its function if its lipidbilayer were readily permeable to hydrogen ions (protons)?
