Overview of Metabolism Flashcards
1
Q
if a reaction has more products than reactants…
A
entropy increases
2
Q
spontaneity (∆G) is affected by…
A
the concentration of reactants and products
3
Q
four life-sustaining molecules
A
proteins, fats, carbs, and nucleic acids
“PrFCaN”
4
Q
metabolism
A
about how we obtain PFCN, and ATP
5
Q
ATP
A
energy currency
- for building up molecules and tissues
- transport molecules across a membrane
- enzyme activity
- movement
- produced in a few metabolic steps
6
Q
glycolysis
A
anaerobic
- taking fuel (glucose) and breaking it down into useful energy
- observed in almost all organisms
- net negative fr ee-energy change
- net output: 2 pyruvates, 2 NADH, 2 ATP
7
Q
OIL RIG
A
Oxidation is losing hydrogens, reduction is gaining electrons
8
Q
in CR, glucose is…
A
oxidized to CO2 (loses all its hydrogens)
