Energy, ATP and Enzymes Flashcards
1
Q
Anabolic vs. Catabolic
A
- Anabolic: requires energy, link molecules together
- Catabolic: release energy, breaking down complex molecules into simpler ones
2
Q
What drives energy conversions?
A
The tendency of energy to become evenly distributed over time- results in a state of higher probability
3
Q
What are first two laws of thermodynamics?
A
1) Energy is neither created nor destroyed
2) Energy disperses spontaneously
4
Q
Formula for entropy- what does G signify?
A
G= H- TdS
- A positive G means energy is required
- A negative G means energy is released
5
Q
What are the two types of enzyme regulation? Explain each
A
- Allosteric
- Competitive
6
Q
What is ATP hydrolysis?
A
Water breaks a phosphate group off, creating ADP and energy.
