Life requires a continual energy flux Flashcards
1
Q
How do we work out if a reaction is spontaneous?
A
if entropy increases
if ΔSsystem + ΔSsurioundings > 0
2
Q
How is the total entropy change of the surrounding calculated?
A
Gibbs equation:
ΔG = ΔHsystem - T ΔSsystem
3
Q
What are heterotrophs
A
Organisms that:
- depend on constant intake of organic sources of carbon from their environment
4
Q
What are autotrophs?
A
Organisms that:
- can survive on inorganic sources of energy
Photoautotrophs will convert energy from light to chemical energy using inorganic molecules as electron donors.
