Draw a labelled diagram showing the structure of a mitochondrion as seen in electron micrographs.

Explain the relationship between the structure of the mitochondrion and its function.

Award marks for any of the following clearly drawn and correctly labelled.
cristae;
inner membrane;
outer membrane;
intermembrane space;
matrix;
ribosomes;
DNA;

cristae provide surface area for oxidative phosphorylation;
inner membrane contains electron transport chains/ATP synthase (which carry out oxidative phosphorylation);
outer membrane separates the mitochondrion from the rest of the cell;
mitrochondrial DNA/ribosomes make (mitochondrial) proteins;
small volume intermembrane space allows for higher concentration of protons;
matrix has enzymes for the Krebs cycle;

In question C2 (a) the drawing was very poor.

(b) proved to be difficult for quite a large number.
