Answer:
The mechanism shut down the oxidation of glucose to CO2 and H2O but increases the oxidation of acetyl CoA derived from fatty acids by Tri carboxylic acid cycle.
Explanation:
When a person eat meal rich in fatty acid,the ingested fatty acid will undergo breakdown to form large amount of acetyl CoA.The so formed Acetyl CoA undergo oxidation by TCA cycle to generate CO2 and H2O.
on the other hand when a person has eaten a meal that is low in carbohydrates(glucose),at that time less glucose molecule will undergo glycolysis and oxidative de carboxylation to form less amount of acetyl CoA.The acetyl CoA accumulates rather than going further oxidation.
As the meal contain low amount of glucose after a certain period of time the glucose level will be depleted.So to maintain homeostasis of body glucose level the gluconeogenesis process is stimulated.
The conversion of pyruvate to oxaloacetate,one of the most important reaction of gluconeogenesis is boosted by the high cellular level of accumulated acetyl CoA.

False, it doesn’t depend on environmental factors
DNA Mutation is caused by the alteration of single base units in DNA, or the deletion, insertion, or rearrangement of larger sections of genes or chromosomes. Thus, the correct answer is option D.
1.DNA Mutations are caused by environmental factors known as mutagens.
2.Types of DNA mutagens include radiation, chemicals, and infectious agents.
3.DNA Mutations may be spontaneous in nature.
