The carbohydrate present in rice is primarily starch. Rice grains contain about 80-85% starch, which is a complex carbohydrate made of glucose molecules. Glucose, fructose, and insulin are not correct - glucose is a simple sugar, insulin is a hormone, and fructose is fruit sugar. Starch is the storage form of carbohydrate in plants like rice.

Ethylene is a natural plant hormone that triggers and regulates the fruit ripening process. It acts as a chemical signal that stimulates the production of enzymes which break down cell walls and convert starches to sugars, making fruits softer and sweeter. Commercially, fruits are exposed to ethylene gas to accelerate and control ripening.

Chlorofluorocarbons (CFCs) are synthetic compounds that were widely used in refrigeration and aerosol sprays. When released into the atmosphere, they drift to the stratosphere where UV radiation breaks them down, releasing chlorine atoms that catalytically destroy ozone molecules, creating the ozone hole.
