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.

In the same way, instead of showing added energy to the reversible reaction, it shows released energy.

Added energy and released energy must be changed.

Added energy should be on the leftReleased energy should be on the right

if I subtract 20 from my number, then square the result, I get the same answer as if I square my number, then subtract 20 from the result
What is my number and how do you work it out?

Answers

The value of the unknown number is 10.5.

Let the unknown number = x

When 20 is subtracted from the number and the result is squared which is equal to the square of the unknown number minus 20:

(x - 20)² = x² - 20

expand the equation;

x² -  40x  +  400 = x²  - 20

collect similar terms together;

x² - x² - 40x = -20 - 400

-40x = -420

[tex]x = \frac{420}{40}\\\\ x = 10.5[/tex]

- ​Cancer isn't a single disease. The term cancer encompasses more than 200 diseases all characterized by the uncontrolled proliferation of cells.

- Cancer cells also fail to undergo programmed cell death, or apoptosis, under conditions when normal cells would (e.g., due to DNA damage). In addition, emerging research shows that cancer cells may undergo metabolic changes that support increased cell growth and division 5start superscript, 5, end superscript.

Genetic Changes and Cancer

Genes carry the instructions to make proteins, which do much of the work in our cells. Certain gene changes can cause cells to evade normal growth controls and become cancer. For example, some cancer-causing gene changes increase production of a protein that makes cells grow.

- People who have certain jobs such as; painting, construction, pesticide and petroleum workers have an increased risk of cancer. Many studies have shown that exposure to asbestos, benzene, benzidine, cadmium, nickel, arsenic, radon and vinyl chloride in the workplace can cause cancer.

- Metastatic cancer causes most cancer deaths, but exactly why it is so difficult to treat is not precisely understood. Metastatic tumors often acquire additional genetic changes from those in the primary tumors that spawned them, and these genetic characteristics may cause them to resist standard treatments.

- Treating cancer is further complicated due to the lifestyle and attitude of patients, the different physiology of people and the rate their bodies will metabolise drugs, the blood supply to the tumour affecting the drug getting into the tumour, the tumour physiology and the fact that the tumour can continue to change.

- The stage of a cancer describes the size of a tumour and how far it has spread from where it originated. The grade describes the appearance of the cancerous cells.

- Cancer treatment options include:

Surgery. The goal of surgery is to remove the cancer or as much of the cancer as possible.

4. How would having a high blood viscosity affect your ability to climb stairs? Explain your answer interms of homeostasis of oxygen/carbon dioxide levels

Answers

Having a high blood viscosity will slow down ability to climb stairs. This is

because high blood viscosity is associated with high blood pressure.

The binding of oxygen to the blood is reduced in a blood with high viscosity

as there is difficulty in the transport of blood for oxygenation due to its

higher density. This allows fro accumulation of carbon dioxide in the blood

which is harmful to body cells.

High blood viscosity will therefore reduce one's ability to climb stairs and

perform other activities.
