Bananas ripen in a refrigerator, but they do so much slower than it left at room temperature.
The skin of a banana turns brown or black faster in the refrigerator, but the banana meat itself does not ripen that much more. In fact, it is recommended that ripened bananas be frozen to preserve them even longer. The cold temperature of a refrigerator encourages an enzyme (polyphenyl oxidase), which is naturally found in the banana, to polymerise phenols in the banana skin into polyphenols. Polyphenols are similar to melanin, the pigment responsible for the color in our skin. This is what blackens the skin of the bananas. Despite the color, the cold temperature will keep bananas firmer than a banana that has been left at room temperature for the same amount of time. The enzymes that break the starch into sugar, which makes the banana soft and ripe, work better at room temperature.

How is a rotten banana a chemical change?
All fruits, bananas included, give off CO2 which helps in the decomposing factor. Since your refrigerator is closed and only has so much space the CO2 builds up and causes them to rot.. Bananas do not "rot" faster in a refrigerator. In fact, they will last longer there. The skin turns brown or black faster in a refrigerator, but the banana meat itself does not ripen that much more.

Do bananas have starch when they are ripe and edible?
They may contain some, but not as much as when they were green or partially ripened. Certain enzymes in bananas are converted to sugars during the ripening process, which is what makes them sweeter and softer as they ripen.

Do ripened bananas influence unripened bananas to start the ripening process?
In a sense, they do. As bananas ripen, they give off heat and ethylene gas, which stimulates other bananas (and other fruit) to ripen.
