What causes a banana's peel to turn brown or black and what causes the fruit to ripen are two different things. A banana's peel turns brown due to an enzyme (polyphenyl oxidase), which is naturally found in the banana. The enzyme polymerises 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.
The enzyme that makes bananas sweet is called amylase. Amylase breaks down the starch in the banana fruit. When the starch is broken into its smaller sugar components, called glucose, the banana tastes sweet. The enzyme that softens the banana is called pectinase. Pectinase breaks down the cell walls in the banana fruit so that it is less firm.
Green and Yellow
Bananas are yellow. Bananas are yellow in hot places like Africa and Spain. But Great Britan bananas are pink because there is not alot of sun there so they don't ripen very well !!!! http://images.Google.co.UK/images?gbv=2&hl=en&safe=active&sa=1&q=a+pink+bananas&aq=f&oq=&start=0 Banana's can also be brown if bruised and green if very ripe at that particular moment
Your penis will turn yellow and shrink. This is called a 'banana hammock'
Yes yellow banana is soft
banana slugs are yellow because they are poisonous.
It is used in science and proofs of proofs in maths, taking an example: Hypothesis: Bananas are red. (There exists) x x (is an element of) Red (and) Banana Banana (implies) Red (not) Red (implies) (not) Banana If a yellow banana is found, (There exists) y y(is an element of)Banana (therefore) y(is an element of) Red There is a contradiction, as the banana must be red, but it is yellow.

Yellow Banana was created on 2001-04-27.
When a banana begins to ripen, the peel begins to change color. It changes from green to yellow to brown. The same occurs with autumn leaves. The green leaves change from green to red and yellow and orange and eventually brown.
banana's are yellow.
No. A banana is a fruit
Yes, because as the fruit ripens, it gives off ethylene oxide gas which speeds up the ripening and consequently the rotting also. When you buy green bananas, putting them in a bag causes them to turn yellow faster.
