Which is wrong for cytochrome P–450

Which one of the following statements about cytochrome P_(450) is wrong

Consider the following statements: Assertion (A) : Most of the detoxification reactions of drugs and alcohol take place in the liver cells. Reason (R) : The smooth ER of liver cells contains an oxidase called cytochroma P-450. Selact the answer using the codes given below: Answer codes:

A cavity of radius r is present inside a fixed solid dielectric sphere of radius R, having a volume charge density of rho . The distance between the centres of the sphere and the cavity is a. An electron is released inside the cavity at an angle theta = 450 as shown. The electron (of mass m and charge –e) will take ((Psqrt(2)mrepsilon_(0))/(earho))^(1//2) time to touc the sphere again. Neglect gravity. find the value of P:

[A]: Smoking causes cancer of tongue, lips & lungs. [R]: It inactivates P 53 genes

There is a pari of bean -shaped organs P in the human body towards the back, just above the waist. A waste product Q formed by the decomposition of unsued proteins in the liver is brough into organ P through blood by an artery R. The numerous tiny filters S present in organ P clean the dirty blood by removing the waste salts, and excess water form a yellowish liquid U which goes from organ P into a bag -like structure V through two tubes W. This liquid is then thrown out of the body through a tube X. (a) What is (i) organ P, and (ii) waste substance Q ? (b) Name (i) artery R, and (ii) vein T (c) What are tiny filters S known as ? (d) Name (i) liquid U (ii) structure V (iii) tubes W, and (iv) tube X
