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.
 
        
             
        
        
        
Lasting genetic similarities make the two bears biological sister species, more closely related to one another than to any others. ... But Ursus maritimus has also evolved to match its polar environment, growing a longer snout than brown bears' and larger, paddle-like paws, both of which aid polar bears in hunting seals.
