•Potential: stored energy •Kinetic: energy that can do work |
Types of energy: |
|
|
• Chemical •Heat •Light •Mechanical •Electrical |
Types of energy in biology: |
|
|
• Energy can't be created or destroyed in a close system. • No energy transformation is 100% sufficient. |
Laws of thermodynamics: |
|
|
Thermal motion of particles |
Disorder in system is due to |
|
|
Measure the disorder in a system (Unusable energy) |
What is entropy? |
|
|
Energy that can do work |
What is free energy? |
|
|
Repeated energy transformation, Free energy is decreasing, entropy is increasing |
What is the phenomenon(increase in entropy)? |
|
|
Enthalpy |
Total enrgy in a body is called |
|
|
🔼G= change in used energy P-R 🔼H= amount of energy added or released from the sysem. 🔼S= unusable energy |
🔼G = 🔼H - T🔼S define each: |
|
|
• Free usable energy is released(spontaneous reaction) • Free usable energy is consumed (non-spontaneous reaction) |
🔼G < 0 = ? 🔼G > 0 = ? |
|
|
•Energy is added. •No energy is added (reduced) |
🔼H > 0 = ? 🔼H < 0 = ? |
|
|
•Big change in unusable energy. •Small change |
🔼S>0=? 🔼S<0=? |
|
|
•Exergonic=Release energy 🔼G= - •Endergonic=Take up energy 🔼G= + |
Types of reaction and energy change occuring in them: |
|
|
•Adenine= nitrogen base •Ribose= 6 carbon sugar •Three phosphate molecules |
ATP is made of: |
|
|
The phosphate acid anhydride bond between phosphate molecules |
What characteristics gives ATP high free enrgy? |
|
|
❌; Into building blocks of nucleic acids |
✔ or❌: ATP can be converted into building blocks of Carbohydrates? |
|
|
- 7.4 to 14 Kcal/mol (- means release of energy) |
How much free energy is released from ATP? |
|
|
