Question

Lactic acid fermentation can be modeled by which equation?(1 point)
Responses

Lactic acid + NADH → Pyruvic acid NADH
Lactic acid + NADH → Pyruvic acid NADH

Lactic acid + NADH → Pyruvic acid + NAD+
Lactic acid + NADH → Pyruvic acid + NAD+

Pyruvic acid + NADH → Lactic acid + NAD+
Pyruvic acid + NADH → Lactic acid + NAD+

Pyruvic acid + NAD+ → Lactic acid + NADH

Answer 1

The correct equation that models lactic acid fermentation is:

**Pyruvic acid + NADH → Lactic acid + NAD+**

In this process, pyruvic acid (the product of glycolysis) is reduced to lactic acid, while NADH is oxidized to NAD+.
