- Give typed explanation not a single word hand written otherwise leave it Need help on 1 question (two part question) 1) A) Add a phosphate molecule onto adenosine. What kind of reaction was performed? What kind of bond is formed? What is the name of this molecule? Draw the structure on paper. B) How would you modify this molecule to make ATP? Draw the structure of ATP. Thank you!This is a visible spectra between 390-590 nm obtained during the protein separation process of haemoglobin and cytochrome c using CM Sephadex chromatography. I'd like the results shown on the image interpreted. Look for characteristic peaks or patterns that correspond to the absorption properties of these proteins in the visible range.i have a question from Lehninger, bichemistry, 13-16 and i know that there is already a copy paste answer from the book for the question on bartleby, howerver I do not understand it and need explained further, as the answere in the book does not help me at all. In the glycolytic pathway, a six-carbon sugar (fructose 1,6-bisphosphate) is cleaved to form two three-carbon sugars, which undergo further metabolism. In this pathway, an isomerization of glucose 6-phosphate to fructose 6-phosphate (as shown in the diagram) occurs two steps before the cleavage reaction. The intervening step is phosphorylation of fructose 6-phosphat to fructose 1,6-bisphosphate What does the isomerization step accomplicsh from a chemical perspective? Consider what might happen if the C-C bond cleavage were to proceed without the preceding isomerization.
