Cell Metabolism

metabolism

decomposition process

• breakdown of organic materials
• carbs, fats, proteins

Stores Energy (ATP)

calorie

• Glycolysis
• Krebs Cycle (TCA)
• Electron Transport System

• first of several reactions in CR
• occurs in cytoplasm
• the one metabolic pathway found in all living organisms
• process makes large amnts of glucose but limited ATP production per molecule of glucose.
• way of producing ATP during brief periods of lack of oxygen
• vigorous exercise
• in cytoplasm
• NAD hydrogen carrier

adenosine triphosphate

7 Kcal

transfer of energy from carbs fats and proteins to many different energy requiring processes in the cell

adenosine diphosphate

adenosine monophosphate

• active transport
• muscle contraction
• growth / mitosis
• brain / nerve transmission

2

• series of several rxns controlled by enzymes in the mitochondria
• function is to free hydrogen
• REDOX reactions (oilrig)

1 glucose = 2 pyruvates

• 8NADH
• 6CO2
• 2ATP
• 2FADH2

loss of electrons with or without their hydrogens

gain of electrons with or without their hydrogens

• the use of oxidation to add Phosphorous to ADP to make ATP
• the passing of hydrogen atoms or its electron from one carrier molecule to another to release energy (redox rxn)
• electron carrier molecules (coenzymes)
• ATP production

• NAD
• FAD
• CoQ
• Cytochromes

NAD

• Flavin Adonine Dinucleotide
• need riboflavin to make it

• transfer electrons
• contain iron or copper

transfer electrons
