I suppose so, it would be more correct to say it was due to a cellular change. Enzymes present in fruits, mainly polyphenol oxidase cause the browning in damaged fruit. Normally polyphenol oxidase works in plants as a defense against insects. When activated this enzyme turns phenols in the plant into quinones, these quinones then turn into melanins which have beneficial properties to the plant as an antibacterial, anti-fungal, and UV protection. Melanins are dark in color and so make the areas where they are present appear brown.
In healthy plant tissue the phenolic compounds are stored in the vacuole of the cell, well separated from the polyphenol oxidase enzyme so no activity happens. However, when a banana is bruised by dropping onto a hard surface or simply overripening, the cells become damaged, the separating membranes are ruptured and polyphenol oxidase can access the phenolic compounds and start the process of turning them into quinones and then into melanins, making brown and black spots in the damaged areas.

Is digesting a banana a chemical reaction or is a reversible change?
Digesting a banana is a chemical reaction, an ireversible change.
Is digesting a banana chemical change or reversible change?
Digesting a banana is a chemical change because enzymes in your digestive system break down the complex molecules in the banana into simpler molecules that your body can absorb for energy. This process involves a chemical reaction that results in new substances being formed.
Is digesting a banana a chemical reaction or is it a reversible change?
Digestion involve chemical reactions, it is a chemical and mechanical process and is irreversible.
Is digesting a banana a reversible change?
No, digesting a banana is not a reversible change. Once the banana is broken down and its nutrients are absorbed by the body, it cannot be easily reconstituted back into its original form.
Is a rotting banana a chemical or physical change?
It's a chemical change
Is digesting a banana a chemical reaction or is a reversible change?
Digesting a banana is a chemical reaction, an ireversible change.
Is digesting a banana a reversibal change or a chemical reaction?
its a a chemical reaction because you can 't get it back in a hole banana

Why is digesting a banana a chemical reaction?
Digesting a banana is a chemical reaction because once that it is already in your mouth you cannot reverse it back as a full banana. *(If that made sense!) LOOL ! :D

Chemical change
Is dissecting a banana a chemical reaction or a reversible change?
Dissecting a banana is a physical change, not a chemical reaction. It involves physically separating the banana into smaller pieces, but the chemical composition of the banana doesn't change. A reversible change would be when you freeze the banana slices and then thaw them, as this can be reversed.
