Theophylline is a pharmaceutical drug that is sometimes used to with lung function. you observe a case where the initial lab results indicate that the concentration of theophylline in a patient's body decreased from m to m in 24 hours. in another 12 hours the drug concentration was found to be m. what is the value of the rate constant for the metabolism of this drug in the body?

Drug metabolism can be defined as the transformation of drug which can be taken orally, subcutaneously, intravenously or by any other mode of intake specifically in the highly complex and difficult to digest form are converted into simpler and easily digestible forms which can facilitate their elimination from the body. The majority of drug metabolic processes occur in the liver as the enzymes responsible for metabolism are present in liver. Rate of metabolism of drug is the time duration in which the amount of drug taken inside the body is completely eliminated from the body. Tolerance of drugs is the amount of drug necessary to get the desired effect. In this case the concentration of theophylline in a patient's body decreased from m to m in 24 hours and further in another 12 hours the drug concentration was found to m this indicate that in first 24 hours the drug had an effect on the body metabolism which the body became tolerant for the the next 12 hours. Therefore the rate constant in this case will become half for the metabolism of drug in the body.

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.

the water is warmed up by the sun and then it evaporates into the atmosphere. the sunlight warms the water by its heat. water is then cooled down and condensation takes place. the water then finally returns back to the earth by the process of precipitation in the form of rain or ice.
