Question

T/F
1. Glycolysis consists of two phases, the hexose stage and the triose stage. A difference is that the hexose stage requires ATP and the triose state produces ATP
2. The third reaction in glycolysis is regulated since other substrates enter after the first reaction is also regulated
3. Gluconeogenesis is simply a reversal of glycolysis that occurs when blood glucose levels fall below normal
4. The Cori cycle is a combination of glycolysis and gluconeogenesis
5. Protein catalysts rely exclusively on the amino acid residues for reactivity at the sites of action
