Phosphopentose isomerase

WebThe pentose phosphate shunt (also known as the hexose monophosphate shunt or the 6-phosphogluconate pathway) shares the intermediates glyceraldehyde-3-phosphate and fructose-6-phosphate with the glycolytic pathway. Both pathways occur in the cytosol and, therefore, have access to one another. WebThe pentose phosphate pathway (PPP) is an alternative way of glucose use. It consists of an aerobic and an anaerobic part. For that reason, the PPP can act as a pathway or a cycle both at the same time. Its aerobic part leads to ribulose-5-phosphate, carbon dioxide (CO2 ), and reduced nicotinamide adenine dinucleotide phosphate (NADPH).

What is the difference between oxidative and non-oxidative?

WebThe nonoxidative phase of the pentose phosphate pathway can be used to convert three molecules of ribose 5-phosphate into two molecules of fructose 6-phosphate and one molecule of glyceraldehyde 3-phosphate. These molecules are components of … WebThe enzyme phosphopentose isomerase is characterized by all the following except a. it catalyzes the interconversion of ribose-5-phosphate and ribulose-5-phosphate b. there is no requirement for ATP c. it converts a ketose to an aldose d. it catalyzes an inversion of configuration at carbon-3

http://dictionary.sensagent.com/Phosphopentose%20isomerase/en-en/ Webphosphopentose isomerase. Under many metabolic conditions the phosphogluconate pathway ends at this point. The net result is the production of NADPH for reductive synthesis and the production of D-ribose-5-phosphate for nucleotide synthesis. However, many cells need more NADPH than ribose-5-phosphate or they may not need ribose-5-phosphate at all.
