Acetylcholine binds to a GPCR on heart muscle, making the heart beat more slowly. The activated receptor stimulates a G protein,
kogti [31]

Answer:

The correct answer is option (b) "addition of a drug that prevents the α subunit from exchanging GDP for GTP".

Explanation:

The G protein is a name given to a family of proteins that act as a switch in diverse cellular processes, transmitting signals from outside to inside of the cells. When a G protein receptor is activated by a neurotransmitter such as dopamine, the alpha subunit exchanges its GDP for a GTP and disassociates G-protein itself. An addition of a drug that prevents this action would prevent  G protein disassociation, which would enhance the effect of stimulating G protein that acetylcholine does.

What chemical formula reflects the diagram
Elden [556K]
Chemical formula is a way of presenting information about the chemical proportions of atoms that constitute a particular chemical compound or molecule, using chemical element symbols, numbers, and sometimes also other symbols, such as parentheses, dashes, brackets, commas and plus (+) and minus (−) signs. These are limited to a single typographic line of symbols, which may include subscripts and superscripts. A chemical formula is not a chemical name, and it contains no words. Although a chemical formula may imply certain simple chemical structures, it is not the same as a full chemical structural formula. Chemical formulas can fully specify the structure of only the simplest of molecules and chemical substances, and are generally more limited in power than are chemical names and structural formulas.

"Consider the reproductive isolating mechanisms described above. Do any of these apply to human beings? Write a few paragraphs i
8090 [49]
Reproductive isolating mechanisms are barriers which impeded mating (prezygotic) or prevent the hybrid from developing properly (postzygotic) but the overall effect is to cause speciation by making it difficult for two diverging species to share genes. So one kind of mechanical isolation could be the usage of contraceptives. As of temporal isolation, or behavioral isolation could be exemplified by people who suffer from diseases that cause separation (such as HIV or cancer). I hope that this is the answer that you were looking for and it has helped you.

Sidana [21]

An enzyme is an organic catalyst.

<h3>What is an enzyme?</h3>

Enzymes are proteins that help speed up metabolism or the chemical reactions in our bodies.

They build some substances and break others down.

All living things have enzymes. Our bodies naturally produce enzymes.

But enzymes are also in manufactured products and food.

Examples of specific enzymes:

Amylase: In the saliva, amylase helps change starches into sugars.

Maltase: This also occurs in the saliva, and breaks the sugar maltose into glucose.

Trypsin: These enzymes break proteins down into amino acids in the small intestine.
