{{hidden|What are the cellular housekeeping functions?|[[ 1) protection from the environment, 2) nutrient acquisition, 3) communication, 4) movement, 5) renewal of senescent molecules, 6) molecular catabolism, 7) energy generation.]]}}
{{hidden|What are the cellular housekeeping functions?|[[ 1) protection from the environment, 2) nutrient acquisition, 3) communication, 4) movement, 5) renewal of senescent molecules, 6) molecular catabolism, 7) energy generation.]]}}
{{hidden|List the cellular compartments and the role in the cell.|[[1) cytosol = metabolism, transport, protein translation, 2) Mitochondria = energy generation, apoptosis, 3) Rough ER = synthesis of membrane and secreted proteins, 4) Smooth ER / Golgi = protein modification, sorting, catabolism, 5)Nucleus = cell regulation, proliferation, DNA transcription, 6) Endosomes = intracellular transport and export, ingestion of extracellular substances, 7) Lysosomes = cellular catabolism, 8) peroxisomes = very long-chain fatty acid metabolism]]}}
{{hidden|Describe the basic structure and functions of the cell membrane.|[[ The plasma membrane is composed of a lipid bilayer of phospholipids studded with a variety of proteins and glycoproteins involved in ion and metabolite transport, fluid phase and receptor-mediated uptake of macromolecules, cell-ligand/cell matrix/cell-cell interactions.]]}}
{{hidden|How are the large complexes in the plasma membrane formed?|They aggregate under the control of chaperone molecules in the RER or by lateral diffusion in the plasma membrane followed by complex formation in situ.]]}}
{{hidden|What are aquaporins?|[[Special integral membrane proteins which augment passive water transport in tissues where water is transported in large volumes.]]}}
{{hidden|How are channel and carrier proteins different?|Channel proteins created hydrophilic pores, permit rapid movement of solutes, restricted by size and charge, where Carrier proteins bind to their specific solutes and undergo a series of conformational changes to transfer the ligand across the membrane, relatively slow transport.]]}}
{{hidden|What is the "multidrug resistance (MDR) protein"?|[[A type of transporter ATPases which pumps polar compounds (e.g. chemo drugs) out of cells which may render cancer cells resistant to treatment.]]}}
