What factors impact the rate of respiration in a variety of organisms?
Factors
What are some general factors that impact the rate of respiration in all organisms?
Temperature
pH
Concentration of enzymes
Concentration of substrate
Availability of oxygen
Presence of an inhibitor
Salt
Respiration
What is the process of respiration and which organisms respire?
Converts glucose into ATP energy
ATP energy is a crucial form of energy for life
ATP drives many functions including activation of enzymes, biosynthesis of macromolecules, and transport of substances across cell membranes
Are there organisms that have a higher rate of respiration compared to other organisms?
Increased movement calls for an increase in cellular respiration
Compared to plants, animals have a higher level of movement, and therefore have a higher rate of respiration
Aquatic animals respire at a higher rate compared to terrestrial animals because concentrations of dissolved oxygen are far lower in water compared oxygen in the air
How does respiration differ across different organisms?
Aerobic respiration
Glycolysis
Krebs cycle
Electron transport chain
Anaerobic respiration
Alcoholic fermentation
Lactic acid fermentation
How can the rate of respiration be measured?
Change in pH
Change in concentration of oxygen
Change in concentration of carbon dioxide
