Question
Select the factor responsible for the change in the colour and taste the bananas. A moisture B. exposure to air C. keeping it at room temperature D. presence of certain cell components
Solution
The factor responsible for the change in the colour and taste of bananas is D. presence of certain cell components.
Here's why:
Bananas contain a plant hormone called ethylene, which triggers enzymes that start the ripening process. These enzymes break down the starches into sugars, making the banana sweet. They also break down the chlorophyll that gives unripe bananas their green color, resulting in the yellow color of ripe bananas.
So, the change in color and taste of bananas is not due to moisture, exposure to air, or keeping it at room temperature, but due to the presence of certain cell components, specifically the hormone ethylene and the enzymes it triggers.
