(a)[3]
A mitochondrion has DNA and ribosomes, and it is the organelle where aerobic respiration occurs. Suggest the roles of the DNA and the ribosomes in a mitochondrion.
(b)[4]
Oxidative phosphorylation occurs in the mitochondrion. The stages of oxidative phosphorylation are shown below, but they are out of sequence. Complete Table 8.1 so that it shows the stages in the correct order.
(c)[1]
ATP is changed into ADP and inorganic phosphate by the enzyme ATPase. State the reaction type involved.
(d)[5]
Some parasitic worms, including tapeworms, live in a mammalian gut where oxygen is absent. Suggest how a tapeworm makes ATP in this setting.
