Question 1
Bread dough is made by mixing flour, water and yeast. If the dough is then kept at about , it expands.
What is the main reason for choosing this temperature?
A
Carbon dioxide expands at this temperature.
B
This is the optimum temperature for the enzymes used in aerobic cell respiration.
C
Lactate produced by anaerobic cell respiration causes the release of carbon dioxide at this temperature.
D
At this temperature, yeast produces carbon dioxide rapidly by anaerobic cell respiration.
