WebGlucose in yeast cells is converted to carbon dioxide and ethanol, which we refer to simply as 'alcohol': glucose → ethanol + carbon dioxide (+ ATP made) This reaction is also called … WebIn Procedure 6, the phenol red changes to yellow. This is because the presence of carbon dioxide produced during aerobic respiration causes the phenol red to become acidic, resulting in a color change from red to yellow. When the yeast cells metabolize the sucrose, they produce carbon dioxide as a by-product.
