Summary Introduction
Introduction:
The plant hormones also called as phytohormones. The plant hormones are chemical substances that regulate the growth of plants. There are five types of hormones present in plants: Auxin, Gibberellins, cytokinins, abscisic acid and ethylene. Auxins regulate the growth of plants, Gibberellic acid regulates the elongation of stems, cyokinin regulate the cell division in plants, abscisic acid helps in abscission of leaves and ethylene cause the ripening of fruit.

- 3. A promising new drug is being evaluated in human trials. Based on preliminary human tests, this drug is most effective when plasma levels exceed 30 mg/L. Measurements from preliminary tests indicate the following human pharmacokinetic parameter values: t1/2,elim = 4.6hr, t1/2,abs = 0.34hr, VD = 0.29 L/kg, Foral = 72%. Based on these parameters, estimate the following if a 49 kg woman were to receive a 1000mg oral dose of this drug: (a) Estimate the plasma concentration of the drug at 1hr, 6 hr, and 20hr after taking the drug ( Concentration estimate) (b) Estimate the time for maximum plasma concentration (tmax). (c) Estimate the maximum plasma concentration (Cmax). (d) Estimate the time at which the plasma level first rises above 30 mg/L. (Note this is a trial and error problem where you must guess a time, plug it into the concentration equation, and determine if it is close to 30 mg/L. Hint: based on part (a) it should be apparent that the answer is less than 1hr.)
