Cholesterol has a much higher profile than the other lipids because of its association with heart disease. Despite its lethal re
yaroslaw [1]

Answer and Explanation:

The mechanism of action of statins begins with the inhibition of a protein called HMG-CoA reductase, allowing its substrate to accumulate in the body and promote cholesterol reduction. At that moment, a transporter called OATP (Organic Anion Transporting Polypeptides) takes statins to the epatic tissue where they will be transformed and metabolized until they are eliminated through bile. This elimination is influenced by the P-glycoprotein, which is the main cause of the efflix presented by the bili. This process can get help from other molecules like some protease inhibitors, digoxin and cyclosporine.

What are the two active sites or domains on a repressor protein?
n200080 [17]

Answer:

DNA binding domain and allosteric domain

Explanation:

Repressors are proteins that inhibit gene expression, They usually have DNA or RNA binding site which enables them to binde to the operator or associated silencers. Allosteric domain is the site for the binding of other molecules, such as  corepressors and inducers that regulate repressor's activity.

An owl has good night vision because its eyes can detect a light intensity as small as 5.0 × 10-13 W/m2. What is the minimum num
Lady bird [3.3K]

Answer:

Thus, the minimum number of photons per second is 77.34

Explanation:

Light intensity, I_{min} =  5\times 10^{-13} W/m^{2}

Pupil has a diameter, d = 8.5 mm

                                      = 8.5 x 10^{-3} m

Radius of the eye, r = 4.25 x 10^{-3} m

∴ Area of the eye, A = \pi .r^{2}

                                 = 3.14\times \left ( 4.25\times 10^{-3} \right )^{2}

                                = 5.6\times 10^{-5} m^{2}

Let P_{min} be the minimum number of photons.

Therefore, P_{min} = I_{min} x A

                                              = 5\times 10^{-13} x 5.6\times 10^{-5}

                                             = 2.8\times 10^{-17} W

Thus the minimum number of photons is given by

N_{min}=P_{min}/E

where E = hc/\lambda

             = \left (6.63\times 10^{-34}\times 3\times 10^{8}  \right )/548\times 10^{-9}

            = 3.62\times 10^{-19} J

Therefore, N_{min} = \frac{2.8\times 10^{-17}}{3.62\times 10^{-19}}

                                              = 77.34 photons per second

Thus, the minimum number of photons per second is 77.34
