Textbook Question
Chapter 17, Problem 5RAT
The yeast in bread dough feeds on sugar to produce carbon dioxide. Why does the dough rise faster in a warmer area?
- (a) There is a greater number of effective collisions among reacting molecules.
- (b) Atmospheric pressure decreases with increasing temperature.
- (c) The yeast tends to “wake up” with warmer temperatures, which is why baker’s yeast is best stored in the refrigerator.
- (d) The rate of evaporation increases with increasing temperature.

Why do the electron-transfer reactions of the cytochromes differ in standard reduction potential, even though all the reactions involve the same oxidation–reduction reaction of iron?
An adult inhales about 6.0××10−4−4 m3m3 of fresh air during a breath. Only 20%% of fresh air is oxygen. Assume the pressure in the lungs is 1.0××1055 PaPaand the air is at a temperature of 300 KK.
How many oxygen molecules are in each breath?
