Concept map on metabolism
Draw a concept map using the words in the list below. Then write a paragraph summarizing your map – it should be clear from your summary that you understand the meaning and significance of each term on the list, and where it fits into the overall concept.
(Your diagram may take any form – flow chart, circle diagram with a central theme and others radiating out from it, etc – as long as it shows how the terms relate to each other and to the main idea. The only unacceptable format is a list of definitions)
Hexokinase
Glucose
Glycolysis
Krebs cycle
Electron Transport Chain
Pyruvic acid
Acetyl – CoA
Fermentation
Lactic acid
Ethanol
Cytochrome oxidase
ATP
NADH
Glyceraldehyde-3-phosphate
Coenzyme-Q
Carbon dioxide
The first step in respiration is glycolysis. The pathway of glycolysis can be seen as consisting of 2 separate phases. The first is the chemical priming phase requiring energy in the form of ATP, and the second is considered the energy-yielding phase. In the first phase, 2 equivalents of ATP are used to convert glucose to fructose 1,6-bisphosphate (F1,6BP). In the second phase F1,6BP is degraded to pyruvate, with the production of 4 equivalents of ATP and 2 equivalents of NADH. The ATP-dependent phosphorylation of glucose to form glucose 6-phosphate (G6P) is the first reaction of glycolysis, and is catalyzed by tissue-specific isoenzymes known as hexokinases.
