Answer:
The food we eat and the air we breathe are two major sources of the carbon atoms that make up the human body.
Step-by-step explanation:
Carbon-containing compounds like carbohydrates, proteins, and lipids are obtained by humans when they ingest plants or items derived from plants. The carbon atoms from these compounds, which are broken down during digestion, are used by the body to create and maintain a variety of tissues and organs. Respiration is an important source of carbon atoms for the human body, in addition to diet. Air that we breathe in contains oxygen (O2) and small amounts of carbon dioxide (CO2) in it. During cellular respiration, which takes place in the mitochondria of our cells, glucose and other organic molecules combine with oxygen to create adenosine triphosphate (ATP), which serves as a source of energy. The human body contains a few more sources of carbon atoms. For instance, carbon atoms are present in water (H2O), albeit in a reduced ratio.
