Which of the following statements about de novo purine synthesis is true?
(A) Purine nucleotides are formed by separately synthesizing the phosphorylated ribose and the purine ring and then joining them together.(B) GMP is formed first and is used as a precursor to form AMP.(C) The synthesis of AMP from inosinate is driven forward by ATP hydrolysis.
(D) GMP synthetase uses NADPH and glutamine to modify the inosinate ring to form GMP.(E) Replacement of the C-1 PPi on PRPP with an amine is required to construct the purine ring on the ribose sugar.

- How many ATP will be produced in an oxidative level phosphorylation of a molecule of glucose in a eukaryotic cell?arrow_forwardWe humans do not express an alpha-Galactosidase enzyme and therefore cannot break down stachyose but the bacteria that live in our large intestine can. These bacteria contain an alpha-Galactosidase enzyme that hydrolyzes the galactopyranosyl-alpha (1-6) glycosidic bonds. The bacteria then ferment the products to generate the gas that is famously associated with eating beans. Draw the Haworth projections of the products of alpha-Galactosidase catalyzed reaction. Name the products of this enzyme catalyzed reaction.arrow_forwardWhat is a justification for a hypothesis stating that copper ion is the necessary cofactor in the catechol oxidase reaction? In other words, what evidence based on observation is there to support this claim? Hints: Citric Acid and EDTA bind to copper ions to inhibit cofactor ability.
