9.1 catabolic processes Flashcards
1
Q
how do they work
A
they break down molecules high in PE to ones that have low PE
- the energy lost is used to do work
- the rest is lost as heat
2
Q
fermentation
A
the partial degradation of sugar without the use of O2
3
Q
Aerobic respiration
A
O2 is consumed as reactant as well as the organic fuel
4
Q
cellular respiration is a- or an- erobic
A
- includes both
- considered aerobic
5
Q
overall aerobic reactions equations
A
organic compounds + oxygen -> carbon dioxide + water + energy
6
Q
cellular respiration equation
A
C6H12O6 + 6O2-> 6CO2 + 6H2O + energy (ATP and heat)
7
Q
cellular respiration free energy change
A
exergonic
G=-686kcal/mole go glucose decomposed
