Responses

dehydration synthesis.

glycolysis

Answer 1

Yeast produces the carbon dioxide responsible for bread rising through **cellular respiration**. Specifically, when yeast ferments sugars in the dough, it undergoes anaerobic respiration, producing carbon dioxide and alcohol. This gas gets trapped in the dough, causing it to rise.
