metabolism
|
the sum of all the chemical reactions that occur in the body.
|
|
anabolism
|
synthesis of molecules, requires input of energy
|
|
catabolism
|
break down of molecules, releases energy
|
|
oxygen
|
final electron acceptor
|
|
aerobic respiration
|
Glycolysis- (glucose + O2- ATP)
transition reaction Krebs cycle (citric acid cycle) electron transport pathway |
|
glycolysis
|
glucose turns into 2 P.A. and 2 ATP and 2 NADH
|
|
glycogenesis
|
glucose converted to glycogen
|
|
glycogenolysis
|
glycogen converted to glucose (liver)
|
|
glucose – 6 – phosphatase
|
in liver
phosphotase released and free flucose |
|
gluconeogenesis
|
liver cells contain another enzyme, lactic acid dehydrogenase, which converts lactic acid to pyruvic acid.
|
|
reverse of glycolysis
|
pyruvic acid is then converted to glu – 6—P
|
|
gluconeogenesis
|
production of glucose from noncarbohydrate molecules, e.g. lactic acid, amino acids, fatty acids
|
|
transition reaction
|
pyruvic acid moves into the matrix of the mitochondrion.
|
|
lypogenesis
|
glucose is converted into glycogen and fats instead
-happens in adipose tissue of liver |
|
lypolysis
|
Triglycerides are hydrolyzed into glycerol and free fatty acids (FFA)
|
|
excess amino acids
|
are deaminated and are converted to carbs or lipids
|
|
transamination
|
A new amino acid can be obtained
|
|
oxidative deamination
|
Excess amino acids are processed for excretion
-amine group is removed and converted to urea, which is then excreted by the kidneys. |
