During the aerobic pathway of carbohydrate metabolism,

The answer would be: ATP is formed slowly, but muscular activity can be sustained for many hours

The main substrate used in aerobic pathway would be glucose, not fatty acids. The glucose will be oxidized by oxygen, not carbon dioxide. The reaction is slow but it will produce much more ATP than the anaerobic pathway. More ATP means there is more energy produced so aerobic pathway is more efficient.

Yes they are correct good day

Aneutral atom must have the same number of neutrons and protons? no, they must have the same number of protons and electrons
