Does ripening banans in a bag with other fruit harm the other fruit?
Our office just got its first fruit shipment, which included an apology for the under-ripe bananas and the suggestion to put them in a brown paper bag along with an apple to speed up the ripening. Does doing this harm the apple?
I'm aware of Why does a brown paper bag speed ripening?, which talks about why this works, but the focus there is on what's happening to the ripening fruit, not what happens to the catalyst. We want to know if using one of the high-quality apples they sent us would lead to regrets.
By browsing this site I've learned that there are other ways to ripen them, including apparently just putting them in the bag without the apple. The instructions from the vendor made me curious about the apple, though, so that's the focus of this question.
(If you make alternate suggestions, please bear in mind that we're in an office with limited kitchen facilities.)

It doesn't harm the apple, but it does speed up its ripening as well. And that risks over-ripening. So your perfectly crispy apples may begin to become mealy. Eventually they become targets for yeasts, molds, etc and start to rot. But it's not making them toxic or causing untoward chemical changes. They're all just speeding each other up.
Yes, you can just put them in a bag without the apple. They will produce their own ethylene (the gas that causes ripening, and which they make while ripening). It may take longer, since under-ripe bananas will put out less ethylene than a ripe apple, but just by a day or two. It's just a question of how hungry you are.

Why should you not put bananas with other fruit?
The reason not to store bananas with other fruit is that the ripening bananas emit a lot of ethylene gas and will cause the other fruit to spoil more quickly. You can also use this to your advantage: got a pear that you want to ripen quicker? Put it in a paper bag with ripe bananas overnight.Can bananas touch other fruit?
After peeling and chopping, banana goes quickly from an appealing yellow to a dingy brown. And crucially, it takes other fruit down with it. This means it rarely makes an appearance in mixes - especially in shop-bought prepared fruit salad. But no longer shall the banana be shunned.Do bananas ripen faster next to other fruit?
Many ripening fruit produce the hydrocarbon gas ethylene as they ripen, which itself triggers more ripening. Bananas are especially productive sources of the gas, and putting one that's in the process of going brown next to apples, pears or hard avocados will greatly speed up their ripening.Does fruit ripen faster with other fruit?
People are often shocked to hear this as it does sound somewhat mysterious and unappetizing but have no fear; ethylene is a natural plant hormone that sets off the ripening process. And, amazingly, any other fruits that are stored in close proximity to apples will ripen more quickly!What happens when you store bananas with other fruits?

Answer 2
The only negative I have ever seen is that the other fruit also ripens (particularly as bananas are themselves one of the most effective producers of ethylene). I don't think I'd put an apple in with a banana, myself, only because the banana will make plenty of ethylene gas; it seems like the apple wouldn't add all that much.
