What makes an organism respire faster?
Internal Factors
Metabolic rate
When an organism's metabolic rate increases, more energy is getting used by the cells for processes like growth and movement. To meet the energy demand, the cell needs to produce more ATP, which is created through cellular respiration. Therefore, as metabolic rate increases, energy needs to be generated wherein respiration is used to provide the necessary fuel to create the actions.
Respiratory enzymes
Respiratory enzyme are essential for organisms as they facilitate the bio chemical reactions in cellular respirations that enable the organisms to efficiently convert glucose to ATP influence the rate or respiration.

Body size
Body size affects the respiration rate of organisms as larger organism generally have lower mass-specific metabolic rates in comparison to smaller organisms.
Larger Organism
Larger organisms have a slower metabolic rate per unit compared to smaller ones. This means that less oxygen is required in relation to their total mass, which means that their respiration rate tends to be slower. Larger organisms also contain complex and efficient respiratory structures, maximizing oxygen exchange. This efficiency allows them to meet their oxygen needs with fewer breaths.
Smaller Organisms
Smaller organisms rely solely on diffusion for gas exchange. This process is efficient because the short distance allows oxygen to quickly reach all parts of the organism through simple diffusion across the cell membrane.

Hormonal influence
Hormones influence the respiratory rate of organisms by regulating metabolic activity and the demand for oxygen. Thyroid hormones are an example of a hormone that influences the respiration rate. These hormones increase the basal metabolic rate through stimulating cellular metabolism. As the hormone rises in level, cells consume more oxygen, which leads to an increase in respiration rate because of a higher oxygen demand.
Environmental Factors
Availability of Oxygen
Low Oxygen Levels: When there is a scarcity of oxygen in an environment, organisms tend to increase their respiration rate to take more oxygen.
High Oxygen Levels: When an environment contains an abundant amount of oxygen, an organism's respiration rate can decrease since minimal effort is needed to meet metabolic oxygen demands.
Temperature
Increased temperature: Higher temperature speeds up the metabolic rate of most organisms. This occurs due to the chemical reaction in cells, wherein a higher temperature results in a faster rate. This results in organisms' cells consuming more oxygen, causing an increase in respiration rate.
Decreased temperature: Low temperature slows down metabolic rate, which affects cells' usage of oxygen, decreasing the rate of respiration.
Response to stress
Stress affects the respiration rate of an organism as the "fight or flight" response will be triggered. When stressed, the nervous system signals the adrenal glands, which release stress hormones like adrenaline, causing several changes. such as:
The respiration rate increases, bringing more oxygen
Muscles receive more oxygen and energy to prepare for rapid action.
Heart rate increases, pumping more blood.
Physical Acitivity
Physical activity increases the respiration rate of organisms as muscles require sufficiient amount of oxygen to produce energy essential for movement.
Body responds to the increase of breath rate and depth to supply more oxygen and remove carbon dioxide.
Artificial Factors
Chemical exposure
Cigarette- contains toxinx that damage the lungs, reducing oxygen uptake
Industraial chemicals- Exposure to these chemicals can impair respiratory health often causing struggles in breathing
Air Pollution
Emissions from vehicles, factories that releases harmful substances or chemical properties that damage respiratory organs, reducing oxygen availabiltiy
Chemical Factors
Sulfur Dioxide (SO₂)- Irritates respiratory tracts reducing lung functionality
Ozone(O₃)- causes inflammation of respiratory tissues
Carbon monoxide - Binds to hemoglobin which reduces the transporation of blood affecting repsiration within organisms
Nitrogen oxides(NO) - Causes oxidative damage to lung tissues
