The type of muscle tissue that does not contain gap junction is SKELETAL MUSCLES.
Gap junction function by allowing the free diffusion of ions and small molecules between two cells. The number of gap junction between any two cells will vary and will depend on the type of cell they are.
Answer:
B. Sends and receives signals throughout the body.
There are choices for this question namely:
Ativan 1 mg orally
<span>Nitroglycerin SL </span>
<span>Serum electrolytes </span>
<span>Chest x-ray
</span>
The correct answer is "Nitroglycerin SL". The SL means sublingually. The physician will still order Nitroglycerin to be taken sublingually whenever there is chest pain. The patient's medication may have been expired being stored for 12 months now. Ativan or Lorazepam will not be given as this is a sedative and there is no indication for sedatives.
Serum electrolytes and chest xray will not be requested as these diagnostic examinations are not usually done in patients with stable angina.
By starch, I'm assuming you mean glycogen, or animal starch.
Similarities:
Both are polysaccharide molecules made from glucose molecules linked together in a long chain.
Both are storehouses of energy.
Differences:
Glycogen is made in animal cells and is the only form of starch animals can digest (unless they have certain microbes in their intestinal tracts to break down cellulose, which all herbivores need).
Cellulose is made in plant cells.
The bonds are a bit different; the molecules are isomers. Glycogen bonds with what is called an alpha 1,4 bond, meaning that the first carbon of one glucose molecule is bonded to the 4th carbon of the next glucose molecule, but in a way that puts the bonds in a shape that falls below the plane of the molecule, and allows branching.
Cellulose bonds with beta 1,4 bonds. The first and fourth carbons of adjoining glucose molecules are still connected, but the shape of the bond falls above the plane of the molecule and does not branch.
Since enzymes are specific to their substrates, the enzymes shaped to fit glycogen bonds do not fit on cellulose bonds, which is why animals cannot digest cellulose on their own. In herbivores, there are microbes in their digestive tracts which can produce enzymes to break these bonds so the glucose can be used. In carnivores and omnivores like humans, there is no enzyme to break down cellulose so it becomes 'roughage' in our diets. It passes through the digestive tract without being broken down.
