Two important coenzymes for oxidising nutrients?
NAD+, NADH, FAD, FADH2
What is metabolomics?
The comprehensive study of all metabolites in a biological specimen
How are metabolomics measured?
MS and NMR of biological samples
What is metabolic capacity?
The ability of an individual to metbolize based on inherited genomes and genetic variation
What is energy expenditure?
The amount of energy burned by an individual, with account for resting metabolic rate, food, physical activity and growth
What is metabolic rate (BMR)?
The basal metabolic rate is the basic amount of energy that your body needs at rest to maintain homeostasis
What is homeostasis?
The optimal functioning conditions of the body that it tries to consistently maintain or return to
Why are there different pathways for different types of molecules (fats, carbs, proteins)?
To regulate the speed of ATP production and either increase it when necessary or decrease it when sparse
Where does glycolysis occur?
Cytosol
Where does TCA occur?
Mitochondria matrix
Where does the electron transport chain occur?
Mitochondrial inner membrane
Why are fats more energy rich?
More hydrogen is a sign of more energy richness
Why does lactic acid cause pain when building up?
Acidosis from pH changes
Two effects of anemia on metabolism
Lowered ATP production
Impaired enzyme function
What is ATP and what are its main functions?
Adenosine Triphosphate is the body’s way of storing energy in a way that can be used for all functions required
Active transport, protein synthesis, muscle contraction
