The CO2 production begins as the fruit ripens enters the climacteric phase, or the period when bananas release ethylene and and have an elevated rate of respiration (along with a great deal of other physiological changes). Physical and chemical properties are not usually applied to biological organisms. For example, when an egg is cooked, the proteins in the egg are transformed into a new substance that cannot be turned back into an egg. Many physical changes are reversible, meaning that the substance can be changed back to its original state. 9 terms.
