When you feel happy, a chemical is released in the brain that goes to your pleasure center. For this chemical to have its effect, it must interact originally with which of the following?
1.endoplasmic reticulum
2.nucleus
3.mitochondria
4.golgi apparatus
5.plasma membrane receptor
And why

Most deffinately Plasma membrane receptor. The plasma membrane of cells have receptors for various substances. When substances interact with a receptor, they cause a change in the cell. For instance, insulin connects to receptors on the plasma membrane, cause a cascade of reactions inside the cells.
The ER's are involved in protein synthesis and filtration
Nucleaus is involved in protien synthesis
Mitochondria produces ATP
and the golgi apparatus basically moves things around the cell

I would say a plasma membrane receptor, because it's like a lock and key, which in turn usually releases something, or opens the door for something else to happen.

i think endoplasmic reticulum, mitochondria and golgi apparatus have no deal with it, because they only produces enzymes and mitochondria build energy.
the answer might be nucleus or plasma membrane receptor, and i do belive it is plasma membrane receptor.

I can help you with part of this, but you will have to use the link below, and do a little reading - okay?
"DOPAMINE" is commonly associated with the pleasure system of the brain, providing feelings of enjoyment and reinforcement to motivate us to do certain activities. DOPAMINE is released (particularly in areas such as the NUCLEUS ACCUMBENS and striatum) by naturally-rewarding experiences such as food, SEX, use of certain drugs and neutral stimuli that become associated with them.
The main actor in the reward system is a chemical called dopamine. When you smell, touch, hear, see, or taste a pleasurable stimulus, the dopamine neurons in your brain start firing in bursts. So-called "burst firing" is how the brain signals reward and modulates goal-directed behavior. But just how the stimulus you perceive causes neurons to switch into or out of this mode has been a mystery. In one area in the brain stem, known as the laterodorsal tegmental NUCLEUS, is critical to normal dopamine function.

there is actual extra beneficial than a dozen breeds that are closest kinfolk to wolves. The checklist is composed of: Afghan Hound, Lhasa Apso, Shiba Inu, Akita, Pekingese, Shih Tzu, Alaskan Malamute, Saluki, Siberian Husky, Basenji, Samoyed, Tibetan Terrier, Chow Chow, Shar Pei is clever once you think of approximately it considering the fact that maximum of those breeds originated in factors of the worldwide that have been inhabitated by guy the longest.

5
because that's the main principle of signal transduction: a ligand/neurotransmitter/hormone binds ti its specific receptor at the cell surface
