Final answer:

All listed options, fermentation, anaerobic respiration, gluconeogenesis and alanine biosynthesis are fates that pyruvate may follow in a cell, meaning none of the given choices is an incorrect fate of pyruvate.

Step-by-step explanation:

The fate of pyruvate within a cell can lead to different pathways such as fermentation, anaerobic respiration, gluconeogenesis, and alanine biosynthesis. However, each of these is indeed a fate that pyruvate may follow under certain cellular conditions. Fermentation can occur under anaerobic conditions where cells convert pyruvate to lactic acid or ethanol. Anaerobic respiration is a process used by certain prokaryotes where pyruvate can be used to create energy in the absence of oxygen. Gluconeogenesis is a metabolic pathway that results in the generation of glucose from non-carbohydrate substrates, including pyruvate. Lastly, alanine biosynthesis is the process by which the amino acid alanine is produced from pyruvate.
