|
Metabolism
|
all chemical reactions necessary to maintain life.
|
|
|
Cellular Respiration
|
Food is broken down within the cell to make their basic organic building blocks, energy from food is created into ATP.
|
|
|
3 Stages of Metabolism
|
Digestion, Anabolism, and Oxidative breakdown.
|
|
|
Digestion
|
Break down food and transport nutrients to tissues.
|
|
|
Anabolism
|
Formation of catabolic intermediates built into lipids, proteins, and glycogen.
|
|
|
Oxidative Breakdowns
|
Nutrients are catobolized to carbon dioxide, water and ATP.
|
|
|
ATP Synthesis
|
the building of ATP from ADP the adding of the 3rd phosphate group.
|
|
|
Hydrolysis of ATP
|
The break down of the ATP molecule into ADP.
|
|
|
Cellular Energy
|
ATP in plants that is captured by the sun and is a process of photosynthesis.
|
|
|
Carbohydrate Catobolism
|
The Hydrogen removed from the glucose is taken to a specific part of the cell to take the energy from it and form ATP.
|
|
|
2 B-Vitamins
|
coenzymes NAD or niacin and FAD Riboflavin are required for the oxidation-reduction reactions to remove the hyrdogen.
|
|
|
Mitochondria
|
The reduced Coenzymes are taken to the cristea of the Mitochondria to produce most of the cells of ATP.
|
|
|
ATP is synthesized in...
|
the substrate level phosphorylation in glycolysis and the krebs cycle.
|
|
|
Glucose is Oxidized into 3 pathways...
|
glycolysis, krebs cycle, and the electron transport chain.
|
|
|
Glycolysis means
|
Sugar/lyses or sugar splitting.
|
|
|
Glycolysis is a 3 phase pathway in which-
|
Glucose is oxidized into pyruvic acid. NAD is reduced to NADH=H. 2 ATP is synthesized by substrate level phosphorylation.
|
|
|
Pyruvic Acid
|
Moves on to the Krebs Cycle in an aerobic pathway. Is reduced to lactic acid in an anaerobic environment.
|
|
|
Importance of Glycolysis
|
Many tissues have reduces amounts mitochondria or limited blood supply. TYPE II muscle fibers, testes, kidneys etc.
|
|
|
Anaerbic Glycolysis
|
with lactate as the end product is the major pathway to ATP production to these structures.
