Factors Affecting Cellular Respiration

By Sue Teresa Tan

Amount of Nutrients

The more nutrients that are available to transform, the more energy results in the cellular respiration process. The types of nutrients that can go through the cellular respiration process and transform into energy are namely fat, proteins and carbohydrates. This also includes amino acids and fatty acids. The carbohydrates converts to glucose, the fats go through the citric acid cycle and the proteins break down and go through glycolysis. The amount of nutrients available to transform into energy depend on the diet of a person. The nutrients go through three processes in cellular respiration. The processes are glycolysis, Kreb’s cycle and the cytochrome system.


Another factor affecting the cellular respiration is the temperature of the environment. Usually, the rate of cellular respiration quickens if the temperature is warmer. The lower the temperature, the slower the rate of cellular respiration is. People who live in warmer environments find it easier to restore their energy as long as there are nutrients available to convert in the body. The reason for this is the enzymes that are present in the cellular respiration process. Enzymes break down easier and then transform into energy quicker when the temperature is higher. Although the temperature affects the rate of cellular respiration, there are no studies that prove more energy production with higher temperatures. The temperature factor just affects the rate of the cellular respiration process.

State of Cell

The state of a cell undergoing the cellular respiration process is a factor that affects the rate of transforming nutrients into energy. Working cells, such as neurons or roots of the human hair, have a higher cellular respiration rate compared with dormant cells like seeds. This is because working cells can store extra energy in the body while dormant cells tend to stay non-motile. For this reason, plant cells do not need to store as much energy as human cells or animal cells do. This is the reason why cellular respiration in plants is a bit different from the cellular respiration process human and animal cells go through.
