Responses
Lactic acid + NADH → Pyruvic acid + NAD+
Lactic acid + NADH → Pyruvic acid + NAD+
Pyruvic acid + NADH → Lactic acid + NAD+
Pyruvic acid + NADH → Lactic acid + NAD+
Lactic acid + NADH → Pyruvic acid NADH
Lactic acid + NADH → Pyruvic acid NADH
Pyruvic acid + NAD+ → Lactic acid + NADH
The correct equation is: Lactic acid + NADH → Pyruvic acid + NAD+
The equation that models lactic acid fermentation is:
Pyruvic acid + NADH → Lactic acid + NAD+
The correct equation that models lactic acid fermentation is:
Pyruvic acid + NADH → Lactic acid + NAD+
To arrive at this answer, we must understand the process of lactic acid fermentation. It is a metabolic pathway that occurs in the absence of oxygen (anaerobic conditions), primarily in certain bacteria and our muscle cells. This process takes place after glycolysis, where glucose is converted into two molecules of pyruvic acid.
In lactic acid fermentation, pyruvic acid is reduced and converted into lactic acid. During this conversion, the coenzyme NADH is oxidized back to NAD+. This recycling of NAD+ is crucial for glycolysis to continue producing ATP (energy) under anaerobic conditions.
Therefore, the correct equation representing lactic acid fermentation is:
Pyruvic acid + NADH → Lactic acid + NAD+
