The following information is about a type of fermentation :

Sodium bicarbonate (baking soda) has been proposed as a performance enhancing aid by reducing acidity in blood during exercise

Adapted from https:llwww.ncbi.nlm.nih.gov/pmc/articles/P MC6544001 I

Why sodium bicarbonate used as a performance enhancing aid in fermentation?

• More energy is produced during oxygen debt

• To increase muscle efficiency during lactic acid fermentation

• Has low pH to neutralise lactic acid produced by muscle cells
