Pyruvatic acids are formed during which stage of cellular respiration

The correct answer is glycolysis.

Explanation:

An array of reactions, which derive energy from glucose by dissociating it into three-carbon molecules known as pyruvic acid is collectively known as glycolysis. The organisms in which cellular respiration takes place, glycolysis is the initial stage of the procedure. The process glycolysis occurs in the cytosol of a cell, and it can be differentiated down into two prime phases, that is, the energy-releasing phase, and the energy-requiring phase.

b - the respond is innate and varies over time.

good luck!
