1. If an enzyme operates at a certain pH, and has been saturated with substrate, what is the best way to speed up the reactions?

increase the enzyme concentration

2. Which of the following metabolic processes can occur without a net influx of energy from some other process?
   1)amino acids → protein
   2)ADP + P i → ATP + H2O
   3) 6 CO2 + 6 H2O → C6H12O6 + 6 O2
   4) glucose + fructose → sucrose
   5) C6H12O6 + 6 O2 → 6 CO2 + 6 H2O

5

3. some bacteria operate in high temperatures b/c

they have a high optimal temperature

4. What will happen if an enzyme is added to a solution where the substrate and the product are in equilibrium?

nothing

5. Catabolic pathways

Energy is released from broken bonds
-bonds reformed and that's how they release energy
down hill reaction
ex - ATP to ADP

6. Anabolic pathways

Consume energy to build things
uphill reaction
ex - photosynthesis

7. 4 types of energy

Kinetic, potential, chemical, thermal

8. Kinetic energy

energy of motion

9. Thermal energy

type of kinet energy associated with the random movement of atoms or molecules

10. Potential energy

energy associated with structure or position
