<span>substrate-level; oxidative
Glycolysis will produce 2 ATP, 2 NADH, and 2 pyruvate molecules. If the body has oxygen, it could continue to do </span>oxidative phosphorylation in the tricarboxylic acid(TCA) cycle which will give much more energy(total 38 ATP) than substrate level phosphorylation.
They speed up chemical reactions
