Practise AP Biology 1.4.A questions by identifying the elements and covalent bonds in glucose while keeping carbohydrate structure within the AP exam scope.
Geneticists investigated the mode of inheritance of a rare disorder that alters glucose metabolism and first shows symptoms in adulthood. The geneticists studied a family in which some individuals of generations II and III are known to have the disorder. Based on the pedigree (Figure 1), the geneticists concluded that the disorder arose in individual II-2 and was caused by a mutation in mitochondrial DNA.

The disorder alters glucose metabolism. Describe the atoms AND types of bonds in a glucose molecule.
