| Question | Answer |
|---|---|
| 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 |
