Nitrogen metabolism

Nitrogen metabolism is the synthesis, utilization or uptake, breakdown, and excretion of nitrogenous compounds in the body. The nitrogen metabolism encompasses nitrogen fixation, biosynthesis, and the breakdown of amino acids, purines, and pyrimidine. Since nitrogen-containing compounds are required for various life processes, nitrogen is an important element of life.

Question

The text states that ATP is synthesized primarily by energy metabolism,
whereas other nucleoside triphosphates are formed from the action of nucleoside diphosphate kinase. What additional pathway exists for GTP synthesis?

Chemical pathways by which living things function, especially those that provide cellular energy, such as the transformation of energy from food into the energy of ATP. Metabolism also focuses on chemical pathways involving the synthesis of new biomolecules and the elimination of waste.

A mutation has occurred that results in phosphofructokinase not being able to bind ATP in its allosteric site. What impact will this mutation have on the production of ATP in the cell? Select one: a. If no ATP can bind to the allosteric site, then phosphofructokinase will not be able to add the phosphate to fructose-6-phosphate to make fructose-1,6-bisphosphate and glycolysis will not work. So no pyruvate, not cellular respiration. b. If ATP cannot bind to the allosteric site, phosphofructokinase will not be activated to make more ATP by substrate-level phosphorylation. c. No impact on the production but will not be able to effectively shut off over production of ATP with feedback inhibition.
Some protein kinases are inactive unless they are phosphorylated on key serine or threonine residues. In some cases, active enzymes can be generated by mutating these serine or threonine residues to glutamate. Explain.

How many ATP and GTP molecules would be hydrolyzed in the synthesis of a 125 amino acid protein? Explain why this is a good argument for careful regulation of gene expression (especially considering that most proteins are larger than 125 amino acids).
