Module 11 Set 3

QuestionAnswer
Pentose-Phosphate pathway: oxidation steps produce NADPH, which is needed for biosynthesis
Pentose-Phosphate pathway: sugar transformation reactions produce sugars needed for biosynthesis
Pentose-Phosphate pathway: sugars can also be further degraded
Pentose-Phosphate pathway function: NADPH produced are source of electron
Pentose-Phosphate pathway function: Source of 4- and 5- carbon sugars for many purposes
Pentose-Phosphate pathway function: Intermediates may be used to produce ATP
Pentose-Phosphate pathway function: NADPH can be converted NADH, which yields ATP
Pentose-Phosphate pathway function: Pentose carbon source can be converted to hexose
Transition Reaction step 1: Connects glycolysis to the TCA.
Transition Reaction step 2: Pyruvate is converted to a two-carbon acetyl group attached to coenzyme A, CO2 is released
Transition Reaction step 3: This oxidation reaction removes electrons from pyruvate by dehydrogenase using NAD+ as coenzyme.
Transition Reaction step 4: Reaction occurs twice for each original glucose molecule.
Tricarboxylic Acid Cycle is also called citric acid cycle and Kreb’s cycle
Tricarboxylic Acid Cycle completes oxidation and degradation of glucose and other molecules
Tricarboxylic Acid Cycle is common in aerobic bacteria, free-living protozoa, most algae, and fungi
Tricarboxylic Acid Cycle is amphibolic: provides carbon skeletons for biosynthesis
