Conversion of pyruvic acid into lactic acid depends upon

What amount of energy is released from glucose during lactic acid fermentation?

Identify the correct combination of $A$, $B$, and $C$ involved in lactic acid fermentation.
$C_6H_{12}O_6 \rightarrow A + B \rightarrow$ Lactic acid + $C$

What is incorrect for fermentation?

Given below are two statements.
$Statement-I$ - Skeletal muscles usually derive energy by anaerobic respiration.
$Statement-II$ - After vigorous exercise,lactic acid accumulates in muscle fibres,leading to muscle fatigue.
In the light of the above statements,choose the most appropriate answer from the options given below:

When a molecule of pyruvic acid is subjected to anaerobic oxidation and forms lactic acid,there is
