(15 points) sthc folowing enzymes: hexokinase, pyruvate dehydrogenase, ATP synthase and a) How do these enzymes interact with their substrates and catalyze reactions? b) What is unique about each type of enzyme and why are each of reactions which they catalyze including major points of regulation (enzyme cataly mechanism of interaction of enzymes with their substrates and enzymes)? the enzymes suited to the specifi sis, the the effect of regulators/inhibitors on hat is the c) W cellular motors? Why? ni toc ofganization of the active site for each enzyme? Are any of these enzymes considered 8. Why is the citric acid cycle considered to be a "central metabolic hub" of the cell? Provide an explanation with specific examples, including control and regulatory aspects of the citric acid cycle. What happens when there are "defects" in the citric acid cycle?Explanation / Answer
7. Hexokinase is an enzyme that phosphorylates the hexose sugars and coverts them into hexose-phosphate. example: when glucose is acted upon by hexokinase enzyme, glucose is converted into glucose-6-phosphate.
pyruvate dehydrogenase is the first component of the pyruvate dehydrogenase complex. pyruvate dehydrogenase complex is a complex enzyme of three enzymes. pyruvate dehydrogenase complex converts pyruvate into acetyl-Co-A by decarboxylation by pyruvate decaroxylation.
ATP-synthase is an enzyme that synthesizes ATPs from ADP and inorganic phosphate. ATP synthase is the complex enzyme that creates or makes ATPs from ADP and inorganic phosphate. ATP synthase is present in the inner mitochondrial membrane of mitochondria.
phosphofructokinase is one of the glycolytic enzymes. It phosphorylates the fructose-6-phosphate into fructose 1,6-bisphosphate.
