Differentiаte between the structure оf chrоmаtin аnd chrоmosome form of DNA. And explain when is DNA present in the chromatin form and when it is in the chromosome form during the life cycle of a cell and explain why?  

Uplоаd аn imаge оf yоur drawing. The role of lactate (CH3CH(OH)CO2-) in metabolism was revaluated in a review article on lactate metabolism by L. B. Gladden in J Physiol 558: (2004) pp 5-30. The paragraph to the below is from the article. La- is lactate. One of the proposed metabolic roles of lactate involves a metabolite shuttle between two types of cells within the brain. Glu is the primary excitatory neurotransmitter in the brain. The proposed shuttle system is shown in an illustration from the above-mentioned article and depicts, among other things, the recycling of Glu. Image Description La- can no longer be considered the usual suspect for metabolic 'crimes', but is instead a central player in cellular, regional and whole body metabolism. Overall, the cell-to-cell lactate shuttle has expanded far beyond its initial conception as an explanation for muscle and exercise metabolism to now subsume all of the other shuttles as a grand description of the role(s) of La- in numerous metabolic processes and pathways.  La- is lactate, Pyr is pyruvate, AAT is alanine amino transferase, 2-oxoglu (2-oxoglutamate) is another name for a-ketoglutarate, GDH is glutamate dehydrogenase, LDH is lactate dehydrogenase  One of the reactions shown in the diagram is the conversion of Glu to Gln. Draw out this reaction. Include the structures of the substrate and product and as well as, the key intermediate structure in the reaction, along with any cofactors or co-reactants required for the reaction.  (2 pts.)
