A. Sink: The medium which reacts with pollutants-is called sink. Ex: Sea water is a big sink for `CO_2`. COD : The amount of oxygen required to oxidise organic. substances present in-polluted water is called Chemical Oxygen Demand. It is an important parameter for determining the quality of water. BOD: The amount of oxygen used by the suitable microorganisms present in water during five days aj 20°C is called Biochemical Oxygen Demand (BOD). TLV: The, minimum level of the toxic, substances-or pollutants present in the.atmosphere which affects a person adversely when he is exposed to this for 7 - 8 hrs. ina day is called Threshold Limit Value (TLV). Receptor: the medium which is affected by .a pollutant js called receptor. Ex : Eyes of drivers of two wheelers, (or)four wheelers when-they are stopped at signal.centres.
Define the following terms and give two examples each. a) Pollutant b) Contaminent c) Sink d) Receptor and e) Speciation
What are enzymes and receptors?
Define the teams Sink, COD, BOD, TLV and receptor.
(A) All receptors are proteins that are crucial to body communication process. (R) Shape of the receptor changes after attachment of chemical messenger and receptor regains structure after removal of chemical messenger.
Insulin receptors are
Define the terms 'Receptor' and 'Sink'.
What is the function of receptors in our body? Think of situations where receptors do not work properly. What problems are likely to arise?
Hormone that is having receptor on the surface of cell membrane is
In cellular respiration, oxygen is used as the final receptor of
(A) Cimetidine is an antihistamine. (R) It prevents the intraction of histamine with the receptors present in the stomach wall.
