9753.	Question : The signal trasnduction of steroid hormone across cell is thorugh
Answer» binding of hormone to the cytoplasmic receptor and the complex binds to hormone response element on DNA within promoter DNA binding of hormone to the transmembrane receptor which intiates the production of second messenger that ACTIVATES enzymes which further activates transcription factors binding of hormone ot the transmembrane receptor which diffuse INSIDE the cell cytoplasm and then activates the enzyme necessary for the activation of transcription factors. binding of hormone to the cytoplasmic r aceptor that initiates the production of second messenger which activates enzymes that further activates transcription factors. Solution :STEROID hormones, being hydrophobic molecules, diffuse freely into all cells and act within the cell. Steroid hormones eneter the cytoplasm of a target cell and bind with SPECIFIC recptor proteins (mobile). Hormone -receptor complex then diffuses intonucleusand activates specific response for a particular steroid hormone.

9774.	Question : The sensory receptors that respond to sound, develop receptor potentials when their
Answer» hair are bent pigments absorb pressure surface proteins are altered by a change in pH. sodium-potassium pumps become deactivated. Solution :The organ of Corti is a structure located on the basilar membrane which CONTAINS hair cells that act as AUDITORY receptors.Movements of the basilar membrane BEND the hair cells, PRESSING them against the techorial membrane.As a result, nerve impulses are generated in the associated afferent neurons.These impulses are transmitted by the afferent fibres via auditory NERVES to the auditory cortex of the brain, where the impulses are analysed and the sound is recognised.

Discussion

9777.	Question : The sense of taste is considered to be the most pleasureable of all senses. Describe the structure of the receptor involved with a diagram.
Answer» Solution :Gustatory receptor: The sense of taste is considered to be the most pleasurable of all senses. The tongue is provided with many small projections called papillae which give the tongue an abrasive feel. Taste BUDS are located mainly on the papillae which are scattered over the entire tongue surface. Most taste buds are seen on the tongue few are scattered on the soft palate, inner surface of the cheeks, pharynx and epiglottis of the LARYNX. Taste buds are flask-shaped and consist of 50 – 100 EPITHELIAL CELLS of two major TYPES. Gustatory epithelial cells (taste cells) and Basal epithelial cells (Repairing cells). Long microvilli called gustatory hairs project from the tip of the gustatory cells and extends through a taste pore to the surface of the epithelium where they are bathed by saliva. Gustatory hairs are the sensitive portion of the gustatory cells and they have sensory dendrites which send the signal to the brain. The basal cells that act as stem cells, divide and differentiate into new gustatory cells.
