Energy Metabolism Flashcards
What is the law of energy conservation
Energy can be converted from one form to another BUT cannot be created or destroyed
Two types of metabolism
Catabolism
Anabolism
Catabolism is
Biochemical reactions to break down large molecules to release energy
Anabolism is
Biochemical reaction to synthesise new molecules by consuming energy
Fatty acids go through? to produce?
Beta oxidation to produce Acetyl-CoA
Glucose go through? to produce?
Glycolysis to produce Acetyl-CoA
Amino acids go through? to produce?
Deamination to produce Acetyle_CoA
The two energy-rich electron donor substances are produced
NADH
FADH2
What is the Electron Transport Chain?
Set of reactions in the mitochondria
NADH & FADH2 give energy to
the electron transport chain
Electron transport train is an
oxidative process
By-products of ETC
H2O and CO2
In the presence of oxygen, the ETC produces how many ATP for carbohydrates
32 ATP
ATP produced in glucose metabolism
Glycolysis - 2 ATP
Krebs - 2 ATP
ETC - 32 ATP
Total: 36 ATP
Carrier molecules in the ETC are
Cytochromes
High to low energy state
The process that synthesises ATP is called
Oxidative phosphorylation
ATP produced by Fat Metabolism
Each 18C fatty acid yields 16 ATP
Therefore each molecule of lipid yields 3 x 146 = 438 ATP
Protein is broken down for energy in
sustain, intense exercise
Starvation when carbohydrates and lips used up
