Multiple Choice

• muscle contraction

Open Ended

Name compound A, process B and C.

Open Ended

What is the role of oxygen in the ETC?

Open Ended

How many NADH and FADH is made from one molecule of glucose (in glycolysis, link reaction and Krebs cycle)?

Open Ended

Why do we add soda lime in the tube?

Open Ended

Describe a method by which the students could set up the respirometer and use it to test their hypothesis: The volume of oxygen taken up by respiration in immobilised Chlorella increases with an increase in temperature. Your method should be set out in a logical order and be detailed enough to let another person follow it. [7]

Draw

Sketch a graph to show the effect of temperature on the average time for methylene blue to decolourise in yeast

Open Ended

Methylene blue is a redox indicator (acts as a hydrogen acceptor, changing colour to colourless when reduced )

Plan an experiment to investigate the effect of temperature on the rate of respiration in yeast using methylene blue.
