Although there are specialized cells-both in structure and function-within the body, all cells have similarities in their structural organization and metabolic needs (such as maintaining energy levels via conversion of carbohydrate to ATP and using genes to create and maintain proteins).
Method 1 of 2: In a Paper Bag. 1. Gather a brown paper bag, the bananas you wish to ripen and an apple or tomato. By placing the bananas in a brown paper bag with another fruit, you will maximize the amount of ethylene gas released.Ethylene gas is the substance fruit produces as it ripens.ethod 1 of 2: In a Paper Bag. 1.

Green bananas contain up to 70-80% starch, on a dry weight basis. During ripening, the starch is converted into sugars and ends up being less than 1% when the banana is fully ripe (2). The most common types of sugar found in ripe bananas are sucrose, fructose and glucose. In ripe bananas, the total content of sugars can reach more than 16% of the fresh weight (2).
