Students will be introduced to the overall process of cellular respiration, understanding how organisms break down glucose to release energy.
Key Questions
- Compare phagocytosis, pinocytosis, and receptor-mediated endocytosis in terms of mechanism, cargo specificity, and cellular role, using examples from macrophage function and LDL cholesterol uptake.
- Explain how the secretory pathway, from ribosome-bound ER through Golgi apparatus to secretory vesicles, ensures the correct post-translational modification, targeting, and release of proteins via exocytosis.
- Evaluate how familial hypercholesterolaemia, caused by mutations in the LDL receptor, demonstrates the physiological consequences of defective receptor-mediated endocytosis, and explain why LDL accumulates in the blood.
