The hox gene provides a huge amount of important information about evolution. Hox genes duplication made increased morphological complexity possible triggering the formation of neural crest cells and allowed them to disperse throughout the body, forming a variety of structures.

Since both glycolysis and gluconeogenesis are irreversible processes, there is no thermodynamic barrier to their simultaneous op
Ede4ka [16]

Answer:C

Explanation:

It is important for the cell not to activate glycolysis and gluconeogenesis at high rate simultaneously because it is expensive for the cell.

In the break down of one molecule of glucose to pyruvate, one ATP is used in the conversion of glucose to glucose-6-phosphate and one ATP is used in the conversion of fructose-1-phoshate to fructose-1,6-biphosohate. While a total of four ATPs are produced.

Making it a net gain of 2 ATP in glycolysis.

Gluconeogenesis  produces no ATP and requires equivalents of 6 ATP (4 ATP and 2GTP) for one molecule of glucose produced.

(Glycolysis +2ATP) + (gluconeogenesis -6ATP) = -4ATP

There's a net loss of 4ATP if both reactions are activated simultaneously.
