What makes an organism respire
Glucose concentration
Main energy source for respiration
Low glucose = less ATP produced
High glucose = increased respiration rate
Temperature
Higher temps increase enzyme activity
Too hot = enzymes denature
Optimal temp = efficient respiration
pH levels
Enzyme activity depends on pH
Acidic pH from lactic acid slows respiration
Body compensates by increasing ventilation
enzyme activity depends on optimal pH
Acidity from latic acid slow respiration
Carbon dioxide concentrations
High CO₂ can lower blood pH
Detected by chemoreceptors
Triggers faster breathing to remove excess CO₂
Phyiscal Activity
Increases energy demand
Stimulates more oxygen and glucose intake
Raises respiration rate to produce more ATP
Oxygen
Efficient ATP production needs oxygen
Low oxygen triggers anaerobic pathways
Required for aerobic respiration
