Pentose phosphate pathway. Phases. Mar 23, 2015 - Pentose Phosphate Pathway Explained (Handout / PPT Presentation) Quick review for students All the important facts that you need to know compiled in an … b) Ribulose and NADPH. However, this pathway does oxidize glucose and under certain conditions can completely oxidize glucose to CO2 and water. Triose, tetrose, pentose, hexose and heptose sugar are generated as intermediate products in pentose phosphate pathway. Role of Glutathione. -- Created using PowToon -- Free sign up at http://www.powtoon.com/youtube/ -- Create animated videos and animated presentations for free. As a fermentation pathway, it is employed mainly by the heterolactic acid bacteria which carry out heterolactic fermentation. 3 What type of tissues … Sort by: Top Voted. Watch Queue Queue. D-ribose 5-phosphate has to be converted back to glucose 6-phosphate in multiple enzyme catalyzed steps. a) Ribulose and ATP. See more ideas about biochemistry, mcat study, physiology. 8)-In the pentose phosphate pathway, the major products are which of the following? Gluconeogenesis: unique reactions. The other product of the oxidative phase is ribose 5-phosphate, which serves as a precursor for nucleotides, coenzymes, and nucleic acids. It participates in 3 metabolic pathways: pentose phosphate pathway, methane metabolism, and carbon fixation. Red Blood cells • detoxify oxidation products • reduce sulfhydral groups • Keep Fe+2 • maintain structure of RBC . e) Xylulose and ATP. Thus alteration of the PPP contributes directly to cell proliferation, survival, and senescence. It employs one cofactor , thiamin diphosphate . The first is the oxidative phase in which … The Hexose Monophosphate Shunt is also known as “Pentose Phosphate Pathway” (PPP).This is an alternative Glucose oxidation pathway.The hexose monophosphate pathway is used for the production of NADPH from NADP.. Under these conditions, the fructose-6-phosphate and glyceraldehyde-3-phosphate generated in the pathway reenter glycolysis. The pentose phosphate pathway (PPP) is also responsible for the production of Ribose-5-phosphate which is an important part of nucleic acids. Pentose Phosphate Pathway ... Role of Pentose Pathway. Learn it the mnemonic way; Give People Proper Reason To Trust! Pentose Phosphate Pathway Pentose Phosphate Pathway Other names: Phosphogluconate Pathway Hexose Monophosphate Shunt Direct oxidative pathway Regulation of the Pentose Phosphate Pathway: Pentose phosphate pathway represents an alternate route for the breakdown of carbohydrates. View HMP.ppt from BIO 124 at University of the Punjab. That's kind of unique, to point out. Pentose phosphate pathway. Pentose phosphate pathway is defined as the metabolic pathway that occurs in all living organisms, and it utilizes the first intermediate product of glycolysis, i.e. As far as I know, the pentose phosphate pathway is the most active in adipose tissue. It catalyses a non-equilibrium reaction and is strongly inhibited by NADPH. Meanwhile, nonoxidative pentose phosphate pathway generates pentose sugars. Pentose phosphate pathway - PowerPoint PPT Presentation. Email: lailakalan@hotmail.com c) Ribose and NADH. 9) Which of the following statements about the oxidative section of the pentose phosphate pathway is correct? a)The pentose phosphate pathway generates NADH. The recycling of 5 … THE PENTOSE PHOSPHATE PATHWAY A metabolic pathway for glucose oxidation in which no ATP is generated Its principal product are - NADPH - Ribose 5 phosphateRibose 5 phosphate Occurs in cytoplasm in two phase : oxidative and non oxidative It is active in liver, adipose tissue, adrenal cortex, erythrocyte and lactating mammary gland. NADPH formed in the oxidative phase is used to reduce glutathione, GSSG (see Box 14-4) and to support reductive biosynthesis. Watch Queue Queue Krebs (citric acid) cycle and oxidative phosphorylation . Title: Pentose phosphate pathway 1 Pentose phosphate pathway. The NADPH is required for biosynthetic reactions such as fatty acid synthesis, cholesterol synthesis, drug reduction, and as a cofactor for some non-synthetic enzymatic reactions. NADPH is also used to reduce (detoxify) Hydrogen peroxide in cell. But, the pentose phosphate pathway is kind of a unique pathway, because it turns out that in this pathway no ATP is consumed or produced. There are two distinct phases in the pathway: the oxidative phase and the non-oxidative phase. The pentose phosphate pathway (PPP; also called the phosphogluconate pathway and the hexose monophosphate shunt) is a process that breaks down glucose-6-phosphate into NADPH and pentoses (5-carbon sugars) for use in downstream biological processes.
