Anaerobic respiration
Aim: to demonstrate the effects of anaerobic respiration (muscle fatigue)
Hypothesis: My hand is getting tired as I do it faster and it becomes harder every time I close and open it
Equipment: A spring-loaded clothes peg
Method:
- Hold the clothes peg as shown in the diagram below
- Relax tour fingers so that the peg closes all the way
- Squeeze your thumb and forefinger so the peg is fully open
- Repeat steps 2 and 3 as quickly as you can until you experience muscle fatigue
Results/observations: you will feel that you hand or fingers (phalanges) are getting tired
Conclusion/Discussion: I saw the pegs and my hand that my hand or fingers are having the energy to move the pegs
Evaluation:
- Explain what type of respiration your cells are using
- At the beginning of the exercise, it’s aerobic
- At the end of the exercise, it’s already Anaerobic
- Write an equation to summarize anaerobic respiration
- Explain why anaerobic respiration is considered ‘wasteful’ respiration
