ELI5: How does a ripe banana contain more sugar than an unripened banana?

Doesn't the contents of the banana remain the same? All the carb contents are broken down within the body into sugar in the end right?

You've pretty much got the answer right there in your question. The banana contains a relatively constant amount of sugar monomers. In the unripe banana those sugars are chained together to make starch, then enzymes in the banana gradually break it back down into sugar over time in the same way your body would. The ripe banana tastes sweeter than the unripe banana because once sugars are chained together to make starch they don't fit into our sugar receptors anymore and we can't taste them.
