Answer:
It is not important for the cell not to run glycolysis and gluconeogenesis at high rate simultaneously because body carry out various metabolic pathaways with respect to body"s requirement for metabolites .
Explanation:
Human bodyphysiology helps to maintain homeostasis of various metabolic intermediates within our body.
It is not that the glycolytic intermediates and end product such as pyruvate always enter the gluconeogenesis process because pyruvate have different metabolic fates beside acting as a precursor for glucose biosynthesis.
Cell does not require glycolytic intermediates and gluconeogenesis intermediates at the same time.
That"s why it is important for the cell not to run glycolysis and gluconeogenesis simultaneously.
1. Oxygen is required for cellular respiration and is used to break down nutrients, like sugar, to generate ATP (energy) and carbon dioxide and water (waste). Organisms from all kingdoms of life, including bacteria, archaea, plants, protists, animals, and fungi, can use cellular respiration.
2. Mitochondria are often called the “powerhouses” or “energy factories” of a cell because they are responsible for making adenosine triphosphate (ATP), the cell's main energy-carrying molecule.
3. Some cells have more mitochondria than others because they need to process more glucose and produce more ATP.
4. The inner membrane folds over many times and creates layered structures called cristae.
5. In physics, a fluid is a substance that continually deforms (flows) under an applied shear stress, or external force. Fluids are a phase of matter and include liquids, gases and plasmas.
6. Cellular respiration is the process through which cells convert sugars into energy. To create ATP and other forms of energy to power cellular reactions, cells require fuel and an electron acceptor which drives the chemical process of turning energy into a useable form.

(D) It uses enzymes to liquefy food and kill bacteria to be further digested in the intestines.
