Aim: To demonstrate the effects of anaerobic respiration (muscle fatigue.
Equipment: A spring-loaded clthes peg
Method1. Hold the clothes peg as shown in the diagram below
-diagram down below
2.Relax your fingers 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.
Explain what type of respiration yoyr cells are using:
(A) at the beginning of the exercise.
Aerobic
(B)at the end of the exercise.
Anaerobic
Write an equation to summarise anaerobic respiration.
Explain why anaerobic respiration is considered 'wasteful' respiration.
Because the total energy yield from each glucose molecule is only a fraction of what is released when compared to aerobic respiration.
