Mitochondria are the energy centers of the eukaryotic cells. In these organelles, ATP (the energy coin of the cell) is produced by the oxidation of pyruvate (Krebs cycle) and oxidative phosphorylation.
- Based on this information, malfunction in MITOCHONDRIA is most likely responsible for Leigh's disease.
- Cellular respiration is series of metabolic reactions by which eukaryotic cells produce energy in the form of ATP from foods and oxygen.
- Cellular respiration has three main stages: glycolysis, the Krebs cycle and oxidative phosphorylation.
- Glycolysis occurs in the cytoplasm, whereas the Krebs cycle and oxidative phosphorylation occur in the mitochondria.

Answer:
a) Maxillopoda is a diverse class of crustaceans including barnacles, copepods and a number of related animals. It does not appear to be a monophyletic group, and no single character unites all the members
b) General Characters of Hexapoda (Insects)
Ø A large taxa, includes insects and a small group of wingless arthropods.
Ø Body plan: 3 parts, head, thorax and abdomen.
Ø Head with six segments.
Ø Thorax with three pairs of jointed legs (hence the name hexapoda)
Ø Head bears a presegmental acron.
Ø Acron bears compound eyes.
