(单选题) Glycogen is the body’s storage form of glucose. When glycogen is degraded, glucose 1-P is formed. Glucose 1-P can then be isomerized to glucose 6-P. Starting with glucose 1-P and ending with two molecules of pyruvate, what is the net yield of glycolysis in terms of ATP and NADH formed?
选项：

A:1 ATP, 1 NADH
B:1 ATP, 2 NADH
C:1 ATP, 3 NADH
D:2 ATP, 1 NADH
E:2 ATP, 2 NADH
F:2 ATP, 3 NADH G:3 ATP, 2 NADH
