Answer:
It is a very good discussion debate, although I believe that the most effective way to generate the actin head to generate such a displacement requires a good full energy currency, which is considered much better by ATP.
Regarding the information sought in 1950 (Straub), he was publishing that he could bind ATP and that during the polymerization of the protein to form microfilaments, it hydrolyzed to ADP + Pi, which remained bound to the microfilament.
Straub suggested that this reaction played a role in muscle contraction, but this is only true for smooth muscle and was not verified experimentally until 2001.
At the point where it is stated that ADP + Pi is necessary for the formation of polymers, it is extremely true and a very good posture.
What we can highlight as false in all this argument is that for muscle contraction ATP is not needed, since for it to occur if or if there must be ATP or energy currency.
Explanation:
Then we can conclude that both statements are valid with the difference that in the case of ADP + Pi it requires more evidence.
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.
