List the quantum numbers associated with all of the 5d orbitals
Whitepunk [10]

Answer:

Here's what I get  

Explanation:

If the orbital is 5d, n = 5 and l=2.

mₗ = -l, -l + 1, -l + 2,  …., l

(mₛ is a quantum number for electrons)

Thus, we can have the following combinations.

\begin{array}{ccr}\mathbf{n} & \mathbf{l} & \mathbf{m_{l}}\\5 & 2 & -2\\5 & 2 & -1\\5 & 2 & 0\\5 & 2 & 1\\5 & 2 & 2\\\end{array}

That makes a total of five 5d orbitals.

The pictures below show what two of them look like.

erica [24]

Answer:

D. Allosteric activator

Explanation:

In an enzyme, the allosteric site is a site/motif different from the active site, (i.e., the site with catalytic activity) which is able to interact with regulatory effector molecules in order to activate or inhibit enzymatic activity by influencing the tridimensional (3D) structure of the enzyme. An allosteric activator is an effector molecule with the ability to bind to a specific enzyme at a different site than the active site, thereby modifying the shape of the enzyme and increasing the affinity of this enzyme for its substrate. Moreover, Adenosine monophosphate (AMP) is a nucleotide composed of a phosphate group, a sugar ribose, and an Adenine (A) base. This effector molecule (AMP) has shown to allosterically stimulate diverse enzymes in physiological conditions (e.g., AMP-activated protein kinase).
