front 1 Where in the body is Glycogen mainly stored? | back 1 In the liver and muscles |
front 2 What are the two types of glucose polysaccharide linkages? | back 2 alpha(1->4) makes long chains alpha(1->6) makes branches |
front 3 The more _____ ends you have, the ______ you build up and break down glucose | back 3 More, quicker |
front 4 Glycogen Metabolism | back 4 -Review slide 4 and practice drawing the mech? |
front 5 When does glycogen breakdown happen? | back 5 During the four Fs and low blood sugar |
front 6 What is phosphorolysis? | back 6 Using a phosphate to break a bond |
front 7 This enzyme cleaves an alpha (1->4) linkage from nonreducing ends. Product is a glucose 1-phosphate | back 7 Glycogen phosphorylase |
front 8 What is the difference between Phosphatase and Phosphorylase? | back 8 Phosphatase removes the Phosphate Phosphorylase uses phosphate to cleave a bond |
front 9 This enzyme removes G1P until 3-4 residues away from an alpha (1->6) branch point. | back 9 Glycogen phosphorylase |
front 10 Describe the steps of the debranching enzyme | back 10 -A transferase transfers the last 3 residues to the nonreducing end of the longer chain -A glucosidase hydrolyzes an alpha(1->6) linkage to cleave off the glucose |
front 11 This enzyme catalyzes a reversible isomerization from G1P to G6P | back 11 Phosphoglucomutase |
front 12 What happens when there is lots of glucose and ATP? | back 12 Glycogen Synthesis |
front 13 What are the steps to Glycogen Synthesis | back 13 Phosphoglucomutase (Activation), Glycogen synthase (Elongation), Glycogen branching enzyme (Branching), |
front 14 What is Glycogenin? | back 14 A protein with Tyrosine residue which adds the Tyr, adds 6-7 more UDP glucose and adds branching |
front 15 Name the regulation when one pathway is on while the opposite is off | back 15 Reciprocal regulation |
front 16 Which regulation has G6P determine what is on and off | back 16 Allosteric Regulation |
front 17 In covalent modification... | back 17 Phosphorylation of glycogen phosphorylase: on Phosphorylation of glycogen synthase: off |
front 18 Glycogen Phosphorylase is in the R state when Glycogen Phosphorylase is _____ | back 18 On |
front 19 What hormones do Glycogen Phosphorylase activate? | back 19 Glucagon and Epinephrine |
front 20 Explain the different types of Muscle fibers | back 20 Slow twitch muscles are good for endurance while fast twitch muscles are good for sprinting short distances. Can be tested by just running and seeing how you feel |
