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?

gluconeogenesis

glycolysis and gluconeogenesis

glycolysis only

gluconeogenesis

Explanation:

The contribution of gluconeogenesis to glucose production increases from about 50% after 14 h, to almost 100% after 42 h of fasting. The amount of glucose that can be synthesized from this amount of protein is approximately 20 g (nitrogen should be subtracted and not all amino acids have carbon skeletons that can be transformed to glucose).
