Item EB059002: Inside an egg as a 5-day old chick grows into a 10-day old chick, oxygen enters through the shell and reacts with molecules from the yolk to release energy for the growth of the chick. Carbon dioxide produced during the chemical reaction leaves through the shell.
A hen lays a fertilized egg that will develop into a chick. The egg shell has tiny holes in it that allow gases to enter and leave the egg. (For these questions, assume that oxygen, carbon dioxide, and water vapor are the only gases that enter and leave the egg). The yolk inside the egg is a source of energy and building materials for the growing chick. Therefore, as the chick grows bigger, the yolk gets smaller.
As the chick grows, what role do oxygen and carbon dioxide play in the chick’s growth?
- Oxygen enters through the egg’s shell. Inside the egg, oxygen is used by the chick as a source of energy and is turned into carbon dioxide. The carbon dioxide then leaves through the egg’s shell.
- Oxygen enters through the egg’s shell. Inside the egg, oxygen reacts with molecules from the yolk to release energy for the growth of the chick. This reaction produces carbon dioxide that then leaves through the egg’s shell.
- Oxygen enters through the egg’s shell. Inside the egg, oxygen reacts with molecules from the yolk to release energy for the growth of the chick. Carbon dioxide can enter and leave through the egg’s shell, but it does not play a role in the chick’s growth.
- Inside the egg, molecules from the yolk are turned into energy for the growth of the chick. This conversion produces carbon dioxide that leaves the egg. Oxygen can enter and leave through the egg’s shell, but it does not play a role in the chick’s growth.

- PS3.D Cellular respiration in plants and animals involve chemical reactions with oxygen that release stored energy. In these processes, complex molecules containing carbon react with oxygen to produce carbon dioxide and other materials.
LS1.C As a result of these chemical reactions, energy is transferred from one system of interacting molecules to another. Cellular respiration is a chemical process in which the bonds of food molecules and oxygen molecules are broken and new compounds are formed that can transport energy to muscles. Cellular respiration also releases the energy needed to maintain body temperature despite ongoing energy transfer to the surrounding environment.
