Question

Glycolysis and gluconeogenesis are both pathways the body utilizes for energy production. Although both pathways employ common enzymes, they are not the reverse of one another. They are also not usually used simultaneously. Which pathway(s) is(are) enhanced during starvation? glycolysis only

Answer 1

Gluconeogenesis is employed when glucose levels are low or exhausted and the body must use other precursors, such as amino acids from protein, lactate, and glycerol for energy. This occurs during starvation

Explanation:

Gluconeogenesis is a continual process in carnivores and ruminant animals, therefore they have little need to store glycogen in their liver cells. Of the amino acids transported to liver from muscle during exercise and starvation, Ala predominates. b-Aminoisobutyrate, generated from pyrimidine degradation, is a (minor) gluconeogenic substrate.

Hope this was helpful

Answer 2

Gluconeogenesis

Step-by-step explanation:

Gluconeogenesis Is the metabolic process that occurs when the body system is starved or low in energy level. It occurs in the liver and helps in the raising of the blood sugar levels.

It uses non carbohydrate substrates. It uses glucogenic amino acids such as Alanine, serine, cysteine, glycine, threonine, and tryptophan. Fatty acids and glycerol which contain the highest amount of energy source in the class of food is also broken down to energy forms such as pyruvate.
