What 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. In the catechol oxidase reaction, benzoquinone is produced. What does benzoquinone do in fruits and plants? How does it preserve food? Does citric acid have this same effect?

What is the stoichiometry of the synthesis of (a) ribose 5-phosphate from glucose 6-phosphate without the concomitant generation of NADPH? (b) NADPH from glucose 6- phosphate without the concomitant formation of pentose sugars?
the reaction catalyzed by glyceradehyde 3-phosphate dehydrigenase is based on NAD+ and a active site cysteine. Also another phosphate group is added. what is the reason for that? a) because one ATP is consumed b) an inorganic phosphate is activated for ATP synthesis C) NADH can be recycld and than converted back to NAD+ for glycolysis d) because one ATP is generated
Two reactions are shown below. These reactions are directly coupled in cells by an enzyme called hexokinase, which is a key enzyme in glycolysis. It is generally the case that reactions that are directly coupled by enzymes share some common reactants. What is the net reaction when these two reactions are combined? Glucose + Inorganic Phosphate + ATP + Water → Glucose 6-phosphate + ADP Glucose + ATP + Water → Glucose 6-phosphate + ADP + Inorganic Phosphate Glucose + ATP → Glucose 6-phosphate + Inorganic Phosphate Glucose + ATP → Glucose 6-phosphate + ADP
The effect of ATP on the allosteric enzyme PFK-1 is shown below. For a given concentration of fructose 6-phosphate, the PFK-1 activity increases with increasing concentrations of ATP, but a point is reached beyond which increasing the concentration of ATP inhibits the enzyme. (a) Explain how ATP can be both a substrate and an inhibitor of PFK-1. How is the enzyme regulated by ATP? (b) In what ways is glycolysis regulated by ATP levels? (c) The inhibition of PFK-1 by ATP is diminished when the ADP concentration is high, as shown in the illustration. How can this observation be explained? *A graph is included for this question*
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.
