In muscle cells, fermentation produces _____.
a) carbon dioxide, ethanol, and NAD+
c) lactate and NAD+
d) carbon dioxide, ethanol, NADH, and ATP
e) lactate, NADH, and ATP
In biochemistry, fermentation can be defined as the extraction of energy from carbohydrates in the absence of oxygen.
Answer. c) lactate and NAD+
Fermentation reacts to NADH with an endogenous, organic electron acceptor. Usually, this is pyruvate formed from sugar through glycolysis. The reaction produces NAD+ and an organic product, an example is a lactic acid also known as lactate.
C6H12O6 → 2 CH3CHOHCOOH
