Physiology: Biological Chemistry: Proteins, Enzymes and pH Questions

HideShow resource information
A species of bacteria grows best in hot acidic water. If the growth rate was 23 at 70'C, and 48 at 80'C, calculate the Q10
48/23=2.09
1 of 5
If the bacterial growth rate decreased to 7 at 100'c, what has happened?
Denaturation.
2 of 5
The bacteria grew best at pH 3.24. What is the hydrogen ion content at this pH?
H+ = 10^-3.24 = 5.75x10^-4
3 of 5
Is this bacteria likely to cause disease in mammals? Explain.
No due to the needed acidic conditions.
4 of 5
What is the equation for Q10?
Q10 = RT/RT-10
