Biology Question on respiration in plants
Dough kept overnight in warm weather becomes soft and spongy because of
A
Fermentation
B
Cohesion
C
Osmosis
D
Absorption of carbon dioxide from atmosphere
Answer
Fermentation
Explanation
Solution
When dough is left out overnight in warm conditions, it becomes soft and spongy due to a process called fermentation. Fermentation is a metabolic process that transforms sugars into acids, gases, and/or alcohol. This process takes place in yeast and bacteria, and in oxygen-deprived muscle cells, as seen in lactic acid fermentation. So, when fermentation happens in the dough, it results in the conversion of sugars into acids or alcohols and the production of CO2, which gives the dough its soft and spongy texture.
