A precursor of the citric acid cycle, a product of glycolysis and a precursor of gluconeogenesis 11 of 27 Gluconeogenesis is The reverse pathway of glycolysis 12 of 27 Glycogen can be stored in the liver and Skeletal muscle 13 of 27 Glycosidic bonds are formed between _____ functional groups Hydroxyl 14 of 27 Glycogen catabolism in mammals is Glycogenolysis 15 of 27 Two molecules of glucose Maltose 16 of 27 Cellulose is a polysaccharide found in ______ Plants 17 of 27 Phosphorolysis The process of breaking a 1, 4 glycosidic bonds 18 of 27 The chemical element ________ is required for the enzymatic reaction that produces phosphoenolpyruvate Magnesium 19 of 27 In response to low glucose levels ________ is released (where's my) Glucagon 20 of 27 In response to high glucose levels ________ is released Insulin 21 of 27 Where would you find glycogen in the cell? Cytoplasm (associated with glycogen particles) 22 of 27 How many enzymes are involved in converting glucose to pyruvate (glycolysis) Ten 23 of 27 Why would high acetyl CoA levels stimulate oxaloacetate formation? High acetyl Co A levels stimulate pyruvatecarboxylase activities, which catalyses the reaction to form oxaloacetate 24 of 27 Glycolysis regulation: Elevated levels of AMP or ATP - would this inhibit or stimulate glycolysis? Elevated levels of AMP – stimulation of glycolysis, elevated ATP - inhibition of glycolysis 25 of 27 Glycolysisis regulated at a number of points, 1.Glucose uptake 2.Hexokinaseactivity 3._________ 4.PK activity 5.Pasteur effect PFK-1 activity 26 of 27 During fasting _______ released from the pancreas stimulates cAMPsignalling pathways that lead to PEPCK gene transcription Glucagon 27 of 27
