Principle of Complementarity ofStructure and Function Function always reflects structure What a structure can do depends on its specificform Examples: Friction ridges of the fingers Folding of the intestinal lining Hardness of bone Ultra-thin lining of cells through which diffusion occurs Survival Needs of Living Things Nutrients chemical substances used for energyand cell building Oxygen needed for metabolic reactions Water provides the necessary environment forchemical reactions Maintaining normal body temperature necessaryfor chemical reactions to occur at life-sustainingrates Atmospheric pressure required for properbreathing and gas exchange in the lungs Homeostasis Describes a relatively stableinternal environment A dynamic state of equilibrium Values of variables fluctuatearound the set point to establish anormal range of values.
Set point: the ideal normalvalue of a variable. What is the set point for bodytemperature? What other variables aremaintained homeostatically? Transcriptional control2. RNA processing control3. RNA transport and localitation control4. Translocation control5. Eckert, Fig. Cell-cell communication: signal moleculesHumoral communication between cells: endocrine andparacrine contact Membrane penetrating small, hydrophobic molecules, cytoplasmic receptors, direct effect on gene activity Hydrophilic molecules, cell-surface receptors, intracellular signaling second messengers sophisticated signaling and signal-amplification mechanisms Ligands: Hormones, cytokines, growth factors, chemoattractants,neurotransmittersReceptor: The molecules that detect ligand and interact with them withhigh specificity and high affinity.
