Which of the statements about Cytochrome P450 biotransfomations of xenobiotics are true (select all that apply)?
A. |
The highest tissue levels of CYP450 enzymes is in the small intestines |
|
B. |
Dietary intake can induce the activity of CYP450 enzymes |
|
C. |
Poor biotransformation of a xenobiotic can be due to a mutation in a cytochrome P450 enzyme |
|
D. |
CYP450 enzymes catalyze the glucoronidation of xenobiotics |
|
E. |
Cytochrome P450 enzymes can be inhibited by xenobioticsCYP450 |
Options B and C are 100% true. Option A is also correct but I'm not 100% sure. Actually it's also found in liver brain etc.
Option D and E are wrong.

Which of the following statements about enzymes are true? Select all that apply: Enzymes increase reaction rates by lowering the energy of the products. Enzymes increase the rate at which products are created by preventing reactions from running backwards. Enzymes increase reaction rates by lowering the activation energy of a reaction. Enzymes increase reaction rates by interacting with the substrate molecules to facilitate the reaction, for example by contorting them to facilitate bond-breakage or orienting them to favor bond formation.
please select all that apply Which of the following statements are true about an annuity? (select all that apply - i.e. just one or as many as all of them) It is a series of equal payments made at regular intervals The present value can be calculated without using a time-value table, simply by adding up all the payments The payment amount can increase over time Payments must occur on an annual basis
Which statements about reflection are true? (SELECT ALL THAT APPLY) Convex mirrors have focal points opposite to their reflective sides. Diffuse reflection can occur because a surface is rough or due to sub-surface scattering. Specular reflection requires that angles of incidence match the angles of reflection. Light reflected off a surface can never be perfectly polarized at any angle.

Which of the following statements are true about molarity and dilution? (Select all that apply.) Molarity is one of many ways to measure the concentration of a solution. The molarity equation can be algebraically rearranged to give the following relationship: moles (M / Liters). The molarity equation can be algebraically rearranged to give the following relationship: Liters (M * moles). Molarity is defined as the number of moles of solute per liter of solvent. When diluting a solution by adding water the number of moles...
Which of the following statements about red giant stars are true? (Select all that apply.) Red giant stars are less luminous than main sequence stars of the same temperature. Red giant stars tend to be more luminous than main sequence stars of the same temperatures because they are larger in size. Red giant stars are less luminous than main sequence stars because fusion happens more rapidly in main sequence stars. A red giant star of a given temperature is more...
Which of the following statements about hybridization are true? Select all that apply: Hybrid orbitals exist in isolated atoms. Hybrid orbitals within the same atom have the same energy and shape. Hybrid orbitals are described mathematically as a linear combination of atomic orbitals. An atom can have both hybridized and unhybridized orbitals at the same time.
1. Which statements about viruses are true? Select all that apply. A. Viruses are ultramicroscopic cells. B. Viruses are infectious particles with a protein coat surrounding the nucleic acid. C. Bacteriophages are viruses that can also infect the animal cells infected by the bacteria. D. Viruses are nonliving. E. Viruses are not living. 2. The touch-me-not plant, Mimosa pudica, is a weed with compound leaves that fold inward and droop when touched or disturbed. The leaves then open a few...
5/ Which of the following statements is/are TRUE? Check all that apply. a/ If a person is overweight or obese and does not eat healthfully, he/she should not bother to exercise. Even moderate, doctor-approved exercise is dangerous for an overweight person and will not help to improve his/her health. b/ As far as the health effects of daily exercise, you can "count" small bursts of exercise; for example, if you get 4 sessions of exercise at 10 minutes each, you...
