Question

when you \feel the burn\ during exercise, its because the oxygen supply is depleted. what are you conducting? alcoholic fermentation photosynthesis lactic acid fermentation glycolysis

Explanation:

When oxygen supply is depleted during exercise, our muscle cells switch to lactic - acid fermentation. Alcoholic fermentation occurs in yeast and some bacteria. Photosynthesis is the process plants use to convert light energy into chemical energy. Glycolysis is the first step of cellular respiration and occurs with or without oxygen, but the "burn" is due to lactic - acid build - up from lactic - acid fermentation.

Answer:

lactic acid fermentation
