The puffed-up appearance of dough is due to the production of
1 \(\mathrm{CO}_{2}\)
2 Water vapour
3 \(\mathrm{O}_{2}\)
4 \(\mathrm{H}_{2}\)
Explanation:
The puffed up appearance is due to production of \(\mathrm{CO}_{2}\) gas. Yeast produces 3 types of enzymes Amylase, Maltase & Zymase complex. Amylase changes small amount of starch into maltose, Maltase changes maltose to glucose, Zymase complex acts on glucose to form bubbles of ethyl alcohol and carbon dioxide.
