Enolase causes a double bond to form in the substrate by extracting a water molecule, yielding phosphoenolpyruvate (PEP). Definition Derived from Greek word Glykys = Sweet Lysis = splitting The process in cell metabolism by which carbohydrates and sugars, especially glucose, are broken down, producing Glucose = (C6H12O6) ATP and pyruvic acid and two "high energy" electron carrying molecules of NADH. gkennedy1994.

Glycolysis is the initial step of glucose metabolism, which is the common pathway in both aerobic and anaerobic respiration. glycolysis occurs in the mitochondria glycolysis is the first step in both aerobic and anaerobic respiration glycolysis produces 2 ATP, 2 NADH, and 2 pyruvate 3. Glucose has been broken down and oxidized into two molecules of pyruvate. There are 10 enzymes involved in breaking down sugar. Photo 3: The image shows the first five steps of glycolysis. 2 ATP invested, 4 produced, meaning a net gain of 2 ATP.

A comprehensive database of glycolysis quizzes online, test your knowledge with glycolysis quiz questions. In the process, a phosphate group from ATP is transferred to glucose producing glucose 6-phosphate. Reply. Add to favorites 0 favs. This phase is also called glucose activation phase. Glucose enters cell, phosphorylated by hexokinase - phosphate group transfers from ATP to sugar, makes glucose more chemically reactive, Glucose-6-phosphate converted to its isomer, fructose-6-phosphate, Phosphofructokinase transfers another phosphate group from ATP, sugar not has 2 phosphate groups and is ready to be split in half, Aldolase cleaves the sugar molecule into two different 3-carbon sugars: 1) Dihydroxyacetone phosphate, 2) Glyceraldehyde-3-phosphate (isomers of each other), Isomerase catalyzes the reversible reaction b/w the two 3-carbon sugars - never reaches an equilibrium because step six only uses gyceraldehyde-3-phosphate, Triose phosphate dehydrogenase catalyzes 2 sequential reactions while it holds glyceraldehyde-3-phosphate in its active site: First, sugar is oxidized by the transfer of electrons and H+ to NAD+ --> NADH - this is a very exergonic reaction, phosphate group is then attached to the oxidized substrate so it has very high potential energy. In step 1, hexokinase (HK) take a phosphate from ATP and add the phosphate to glucose to create glucose-6-phosphate. The glucose enters the cell and through phosphorylation, a phosphate group from ATP is transferred to sugar. In this process, ATP is regenerated, just like step 7. by dougster91 Plays Quiz not verified by Sporcle . The last step in glycolysis is catalyzed by the enzyme pyruvate kinase (the enzyme in this case is named for the reverse reaction of pyruvate’s conversion into PEP) and results in the production of a second ATP molecule by substrate-level phosphorylation and the compound pyruvic acid (or its salt form, pyruvate).
