Make a large diagram of a mitochondrion. Add annotations to your diagram to explain how the structure of the mitochondrion is adapted for its function.

Glucose can be used to produce ATP, without the use of oxygen:

glucose$\to$X$\to$Y in mammals

                 $\downarrow$

                  Z in yeast

Which compounds are represented by the letters X, Y and Z?

Copy and complete the table to show the respiratory substrates with each of the given RQs.

Measurement of oxygen uptake and carbon dioxide production by germinating seeds in a respirometer showed that 25cm³ of oxygen was used and 17.5 cm³ of carbon dioxide was produced over the same time period.

Calculate the RQ for these seeds

Measurement of oxygen uptake and carbon dioxide production by germinating seeds in a respirometer showed that 25cm³ of oxygen was used and 17.5 cm³ of carbon dioxide was produced over the same time period.

Identify the respiratory substrate used by the seeds.
