Lactic acid fermentation can be modeled by which equation?

(1 point)
Pyruvic acid + NADH
→ Lactic acid + NAD+
Pyruvic acid + NAD+
Lactic acid + NADH
• Lactic acid + NADH →
Pyruvic acid + NAD+
Lactic acid + NADH →
Pyruvic acid NADH

Lactic acid fermentation can be modeled by the equation:

Pyruvic acid + NADH → Lactic acid + NAD+.

The correct equation to model lactic acid fermentation is:

Pyruvic acid + NADH → Lactic acid + NAD+

The equation that models lactic acid fermentation is:

Pyruvic acid + NADH → Lactic acid + NAD+

To arrive at this answer, you need to understand the process of lactic acid fermentation. Lactic acid fermentation occurs in certain microorganisms and muscle cells under anaerobic conditions, meaning in the absence of oxygen. Here's a step-by-step breakdown of the process:

1. Glycolysis: Glucose is broken down into two molecules of pyruvic acid through a series of enzymatic reactions. This happens in the cytoplasm of the cell and does not require oxygen.

2. Conversion of Pyruvic Acid: In lactic acid fermentation, the pyruvic acid produced in glycolysis is converted into lactic acid. This process involves the transfer of two hydrogen atoms from NADH to pyruvic acid, producing NAD+ and lactic acid as the end products.

The balanced equation for this process is:

Pyruvic acid + NADH → Lactic acid + NAD+

This equation shows the conversion of pyruvic acid to lactic acid, facilitated by the transfer of hydrogen from NADH to pyruvic acid.

Therefore, the correct answer is:
Pyruvic acid + NADH → Lactic acid + NAD+
