Unit 3.2: Fat Metabolism
3.2: Carbohydrates and fat metabolism
Metabolism: the chemical processes or reactions in living organisms required for the maintenance of life.
Metabolism includes catabolism and anabolism.
Catabolism Anabolism
Chemical reactions that break down complex large e.g.: glucose molecules turn into glycogen
organic compounds into simpler compounds. (glycogenesis)
Releases energy
ATP is converted to ADP and phosphate
(hydrolysis of ATP)
Aerobic: uses oxygen
e.g.: triglycerides turn into glycerol and fatty
acids
Anaerobic: doesn’t use oxygen
e.g.: glucose turns into lactic acid Small molecules—> (ATP in —> ADP+Pi out) —>
large molecules
ADP and phosphate are turned to ATP
(phosphorylation)
Large molecules—>(ADP+Pi in—>ATP out)—>
smaller molecules
Small molecules are combined into larger
molecules
Requires energy
