Good coronary circulation select one:

1 answer:

7 0

Good coronary circulation nourishes the heart and reduces the risk of a heart attack. Coronary arteries supply blood to the myocardium and other components of the heart. They originate from the left side of the heart at the base of the aorta. The heart muscles needs oxygen-rich blood to be able to carry out its functions.

Answer:

Remain with the client and be silent

Explanation:

Bowel obstruction can be explained or described as a situation whereby the intestines, i.e, both small and large intestines are blocked, and thereby, preventing the normal movement of food, liquid or stool in the intestines.

The blockage could result or occur due to tumor, foreign substance or digestive problem.

The Miller-Abbott tube is the tube that was invented or developed to treat the obstruction that is present in both the small and the large intestines. It is used by passing it through the stomach into the intestine.

In this case, the bowel obstruction is caused by recurrent malignancy, that is recurrent of formation of tumor.

The best thing the nurse should do, is to remain silent and with the client, until the client is ready for explanation on the process, and that he/she is in position and capable of inserting the tube.

There is an error in the above model.

ATP hydrolysis is the lysis of the molecule mediated by water. It releases a phosphate group and energy. It is a reversible reaction. (a) Reversible ATP hydrolysis. (b) added energy on the left and released energy on the right.

------------------------

ATP is a significant molecule involved in many of the cellular metabolic routes. These metabolic processes can either form it or break it.

ATP provides energy to many different functions in the organism.

ATP means adenosine tri-phosphate. It is composed of adenosine (an adenine plus a ribose), and three phosphate groups.

Note: you can also find adenosine Diphosphate (two phosphates) and adenosine monophosphate (one phosphate).

Oxygens from the phosphate groups only have a single bond to phosphate (there are no hydrogen bonds).

These single bonds, known as phophoanhydrid bonds, have a negative charge and tend to repel each other, making the molecule unstable.

So phosphate groups repel each other, and a considerable amount of energy is applied to keep them united. So phophoanhydrid bonds are high energetic bonds.

The forces that keep the phosphate groups together accumulate potential energy.

If these bonds are broken, part of this potential energy would be released.

When talking about breaking the molecule, we are referring to ATP hydrolysis. And the released energy is used in different cellular processes that require energy.

ATP Hydrolysis is the molecule lysis mediated by a water molecule.

ATP + H₂O ⇄ ADP + Pi + Energy

Pi is the released inorganic phosphate group.

This is a reversible reaction, meaning that the ADP can go back to ATP.

ADP + Pi + Energy ⇄ ATP + H₂O

(a) What is this a model of?

This model represents the reversible ATP hydrolysis.

In the superior part of the image, we can see an ATP molecule composed of adenine, ribose, and three phosphate groups. The yellow star behind represents the accumulated energy.

When ATP hydrolysis, it loses a phosphate group and part of the energy that was keeping this group in the molecule.

An ADP is composed after hydrolysis. We can see this molecule in the inferior area of the image.

ADP molecule is composed of adenine, ribose, and two phosphate groups.

Because hydrolysis is a reversible process, by adding a new phosphate inorganic group and energy, we can get a new ATP.

(b) Explain how you would change the model to make it correct?

What is wrong with this model is that instead of showing released energy during the hydrolysis process, it shows energy added to the reaction.
