What makes an organism respire faster?
Factors:
Plants
Plants are easy to grow and contain compounds that support respiration studies. They are useful for testing the effects of light, glucose, and temperature.
Yeast Cells
Yeast grows quickly and is easy to culture in labs. It responds rapidly to environmental changes, making it great for short-term respiration experiments.
pH
Testing pH is simple, low-cost, and well-researched. It provides clear effects on enzyme activity and helps explain how respiration responds to environmental changes.
Animals
Animals show real-time respiration changes and offer insight into human biology. They are useful for studying complex systems, though more care and resources are needed.
Factors Effecting Respiration:
Glucose Availability:
Glucose is the primary fuel used in respiration. An increased supply of glucose usually leads to a faster respiration rate, as more substrate is available for energy production. This has been tested by altering glucose concentrations in different organisms.
Oxygen Concentration:
For organisms undergoing aerobic respiration, oxygen is essential. A higher oxygen concentration allows for more efficient ATP production. When oxygen is scarce, organisms may switch to anaerobic respiration, which is less efficient.
Enzymes Activity:
Enzymes are responsible for catalyzing the chemical reactions involved in respiration. Their efficiency greatly affects the speed of respiration. Factors like temperature, pH, and substrate concentration all influence enzyme activity.
Measurement of Respiration:
Carbon Dioxide Output: Produced in both aerobic and anaerobic respiration; measurable using CO₂ sensors or chemical indicators.
End products:
Ethanol is produced by yeast during anaerobic respiration. It forms along with carbon dioxide and can be measured using chemical tests or chromatography, making it a clear sign of fermentation.
Lactic acid forms in animals during anaerobic respiration, especially when oxygen is low, like during intense exercise. It causes muscle fatigue and indicates a shift to anaerobic energy production.
Oxygen Uptake: Indicates aerobic respiration. Measured using respirometers or oxygen sensors.
Limitations of Factors:
Yeast
Yeast can grow too rapidly, making it hard to control experiments over time. Contamination and inconsistent growth conditions can affect results.
Plants
Plant responses can be slow and affected by multiple variables like light, humidity, and temperature, making it hard to isolate specific factors.
Animals
Using animals raises ethical concerns and requires more care, time, and resources. Their complex systems can make results harder to interpret clearly.
pH
Extreme pH levels can denature enzymes, stopping respiration completely. It can also be hard to maintain a stable pH over time during experiments.
Type of respiration:
Respiration is the metabolic is the process in which cells obtain energy in the form of ATP (adenosine triphosphate). This process can occur in two forms.
Aerobic respiration
Requires oxygen; more efficient, produces more energy (ATP). C6H12O6 + 6O2 ----> 6CO2 (Glucose + Oxygen ----> Carbon Dioxide + Water)
Anaerobic respiration:
Does not require oxygen; less efficient, yields less energy. C6H12O6 ----> 2C3H6O3 (Glucose + Lactic Acid)
