Yes it is.
1. First step: a physical change 2. Second step: a chemical change
Digesting an apple is a chemical change because the enzymes in your digestive system break down the complex carbohydrates, proteins, and fats in the apple into simpler molecules that can be absorbed by the body. This process involves the chemical breakdown of the apple's nutrients.
Digesting a banana is a chemical reaction, an ireversible change.
Its a chemical change.
Eating an apple is both chemical and physical. By biting and chewing the apple you are causing a physical change in the apples general structure- nothing chemical. But when you swallow the apple and your stomach acid breaks down the apple and absorbs nutrients you are exerting a chemical change.
Chemical Reaction
When digesting an apple, chemical energy is released. This energy comes from breaking down the carbohydrates, proteins, and fats in the apple into smaller molecules that the body can then use for energy production.
The digestion of food through the alimentary canal involve a series of chemical and physical changes. In the example of pizza its bread component undergoes chemical changes as it is digested by amylase enzymes in saliva. Other chemical changes include hydrochloric acid of the stomach "attacking" and digesting proteins found in the pizza.
When digesting an apple, the chemical energy stored in the apple is converted to mechanical energy through the movement of our muscles to break it down. This mechanical energy is then converted into chemical energy in the form of adenosine triphosphate (ATP) through cellular respiration to be used as energy by our cells.
it is a chemical change
Digesting French fries is a chemical change because the process involves breaking down the molecules in the food through enzymes and acids in the stomach to extract the nutrients for absorption into the body. This results in a change in the chemical composition of the food.
Food digestions involve many chemical reactions.
