1
Q
what re the 3 fuels for energy provision?
A
1) glucose polymers
2) triglycerols
3) proteins
2
Q
what are the 2 micronutrients?
A
1) vitamins
2) minerals
3
Q
what is GABA?
A
y-aminobutyate, a neurotransmitter derived from glutamate
4
Q
what is the GABAa receptor?
A
a membrane bound ligand-gated chloride channel
5
Q
what occurs when the GABAa receptor is activated?
A
selectively conducts CI- ions causing an inhibitory effect on neurotransmission by reducing the chance of a successful action potential
-damps down responses to other stimuli
6
Q
what is the fuel source from alcohol? (specific number)
A
29 kJ/g
7
Q
what enzyme metabolises alcohol?
A
alcohol dehydrogenase
8
Q
what does alcohol metabolism slow down?
A
- citric acid cycle
- electron transport
- pyruvate dehydrogenase
- glycolysis
- fatty acid oxidation
- inhibits gluconeogenesis
- decreases blood pH
