Lactic acidfermentation can be modeled by the following equation: Pyruvic acid + NADH → Lactic acid + NAD+
LACTIC ACID FERMENTATION:
Fermentation is a process undergone by some anaerobic organisms. Ideally, the process of cellular respiration proceeds as follows in the presence of oxygen: Glycolysis- Kreb cycle - ETC.
However, in the absence of oxygen (anaerobic condition), the product of glycolysis which is pyruvic acid combines with an electron carrier (NADH) to give rise to lactic acid and NAD+.
This means that pyruvic acid is reduced while NADH is oxidized as modelled in the following equation:
The process in which the floors of a building collapse on one another is known as a pancake collapse. This will make the correct answer here B, pancaking.
