Observing the Effects of Anaerobic Respiration {experiment}


15/03/18
Aim- To demonstrate the effects of anaerobic respiration{muscle fatigue}
Equipment- A spring-loaded clothes peg.
Method:
1: Hold the clothes peg as shown in the diagram.

2: Relax your thumb so that the peg closes all the way

3: Squeeze your thumb and forefinger so the peg is fully open.

4: Repeat steps 2 and 3 as quickly as you can until you experience muscle fatigue.

1} Explain what type of respiration your cells are using:
    {a} At the beginning of the exercise:
Aerobic
    {b} At the end of exercise:
Anaerobic

2} Write an equation to summaries anaerobic respiration.
Glucose--- lactic acid+small amount of ATP (energy)

3} Explain why anaerobic respiration is considered "wasteful" respiration.
Because the total energy yield from each other glucose molecule is only a fraction of what is released when compared to aerobic respiration.

Observation:
Since we used a elastic rubber band we experienced muscle fatigue a lot faster in my opinion than a peg.
