How Are Steps 1-3 of Glycolysis Different from Steps 6-10

How are steps 1-3 of glycolysis different from steps 6-10?

A) Steps 1-3 occur in the cytosol, while steps 6-10 occur in the mitochondrial matrix.
B) Steps 1-3 catalyze changes in a six-carbon molecule, while steps 6-10 catalyze changes in a four-carbon molecule.
C) Steps 1-3 catalyze reactions that require ATP, while steps 6-10 catalyze changes that require NADH.
D) Steps 1-3 catalyze reactions that require ATP, while steps 6-10 catalyze changes that produce NADH and GTP.
E) Steps 1-3 catalyze reactions that require ATP, while steps 6-10 catalyze changes that produce NADH and ATP.
