Assume that the binding of one molecule of epinephrine to a seven-transmembrane helix (7tm) receptor (also called the g protein-coupled receptor, or gpcr) results in the activation of 2.0*10^2 gα subunits. in addition, suppose that each activated adenylyl cyclase catalyzes the conversion of 40 atp molecules to camp per second. (assume that each g protein activates a single unique adenylyl cyclase.) calculate the number of moles of camp that are produced per second. enter your answer to at least two significant figures.

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.  

you need to have a picture of the atom that way we can answer it

b.false that your answer
