(a) (b) (c) (d) (e) (f) (g) (h) (i) 2. (a) Metabolism describes all the chemical processes of life taking place inside the cell. Examples include cellular respiration, fatty acid oxidation, photosynthesis, digestion, urea cycle, and protein synthesis. (b) Catabolic: Digestion, cellular respiration, fatty acid oxidation. In these processes, larger molecules are being broken down to smaller ones, releasing stored energy. (c) Anabolic: Protein synthesis, photosynthesis, urea cycle. In these processes, smaller molecules are built up into larger, more complex ones, and are energy requiring. Features: Motile, flagellated cell with mitochondria. Nucleus forms a large proportion of the cell. Role: Male gamete for sexual reproduction. Mitochondria provide the energy for motility. (h) Osteocyte: Features: Cell with calcium matrix around it. Fingerlike extensions enable the cell to be supplied with nutrients and wastes to be removed...
