Extracted text: In muscle cells, the AG for glucose+ATP2 glucose-6-P+ADP is –33.5 kJ•mol-'. In contrast, the AG for glucose – 6 – P fructose – 6 - P is –2.5 kJ · mol-1. (a) In a physiological context, which reaction is faster? How do you know? (b) The enzyme that catalyzes glucose + ATP 2 glucose important point of regulation in glycolysis, while the enzyme that catalyzes glucose – 6 – PZ fructose – 6 – P (phosphoglucose isomerase) is not. Why is hexokinase a good step at which to regulate glycolysis relative to phosphoglucose isomerase? 6 – P + ADP (hexokinase) is an | - |
