The answer would be: <span>ATP </span><span>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.
The answer would be the last one because a deletion changes every codon configuration that follows it and thus changes the amino acid that codes for that codon
