Question

quiz 6: cellular respiration quiz
lactic acid fermentation occurs in
○ bread dough
○ any environment containing oxygen
○ muscle cells
○ mitochondria

Explanation:

Lactic - acid fermentation occurs in muscle cells when there is a lack of oxygen during strenuous exercise. In bread dough, alcoholic fermentation occurs. Lactic - acid fermentation is an anaerobic process, so it does not occur in oxygen - containing environments. Mitochondria are the site of aerobic respiration steps like the Krebs cycle and oxidative phosphorylation, not lactic - acid fermentation.

Answer:

C. Muscle cells
