Cellular Respiration is a chemical process that all living cells undergo. When a cell respires, glucose and other food molecules are broken down and in turn release chemical energy. Chemical energy is used for growth, movement, and even storage for the cell. Cellular Respiration is a major way for cells to keep cool in a warm environment. When yeast cells ferment this is only one type of their cellular respiration.

Turtles and Most Reptiles are cold blooded animals. Cold Blooded Animals- Cold Blooded Animals have the benefit of being able to regulate their blood temperature depending on their environment. Cold blooded animals are known as polikilotherms which in Greek means changeable. Warm Blooded animals maintain a fairly constant blood temperature. Homeotherms which in Greek means same. Lions are Warm Blooded and maintain a constant temperature.

Rattlesnakes are examples of poikilotherms. They are cold-blooded. Rattlesnakes are examples of poikilotherms. They are cold-blooded. Poikilotherms are less active when temperatures are low and are more active when temperatures are high. Poikilotherms are less active when temperatures are low and are more active when temperatures are high. For example, when the night comes, a poikilotherm will become less active because the temperature drops. For example, when the night comes, a poikilotherm will become less active because the temperature drops.

Water-dwelling poikilotherms like fish, do not change their temperature and behavior as much because the water temperature does not change as fast. Water-dwelling poikilotherms like fish, do not change their temperature and behavior as much because the water temperature does not change as fast. In the winter, when ponds freeze, the top layer of ice acts as an insulator for the fish. In the winter, when ponds freeze, the top layer of ice acts as an insulator for the fish.

Some amphibians that live in very cold climates hibernate during the coldest part of the winter. Some amphibians that live in very cold climates hibernate during the coldest part of the winter. Other poikilotherms have chemicals in their cells that inhibit the formation of ice crystals, enabling them to survive when temperatures fall below freezing.

– Homeotherms have a constant body temperature that is usually higher than the surrounding temperature. – They constantly lose energy to our surrounding except on very hot days. – A homeotherm may require up to 10 times the amount of energy of a poikilotherm needs in the same environment. – Homeotherms require more food. – Examples of homeotherms include: Humans- If their body temperature gets too low, their body starts to shut down. (Muscle failure) Humans- If their body temperature gets too low, their body starts to shut down. (Muscle failure)

Humans and Homeotherms Chad M. Chandler A. Daniel K. Michael M.

Homeotherms Such as humans have body systems that regulate internal body temperature. Brain signals body parts to initiate a certain process.

Increasing and decreasing temp. There are two times the brain sends signals to the body. There is increasing or decreasing heat production in metabolic activity. By increasing or decreasing heat flow from the body to the environment.

Examples When body temperature rises above normal, brain increases blood flow to the vessels If body temperature drops below normal, the brains thermostat increases to generate more heat and reduces blood flow to the vessels in the skin.

Homeostasis Homeostasis- the maintenance of stability in an organisms internal environment regardless of external changes.
