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

At the end of binary fission, the two daughter cells that result are genetically _________ to each other and to the parent cell.
A. different
В. identical
C. similar

How has vehicle fuel consumption in comparison to miles traveled changed since 1960? What is the likely cause for this change?
Answers
Answer:
After World War II, economic growth, population growth, rapid suburbanization, and the closing of some public transit systems led to more reliance on personal vehicles for transportation. The number of cars and trucks in the United States increased dramatically, as did the number of highways. One result of the rapid increase of motor vehicles was air pollution, especially in cities, that had serious impacts on public health and the environment.

Read this paragraph from "How Water Loss Affects Biodiversity."
“When a region experiences a significant drought, many animals may die from lack of water and food. […] If tourism declines due to high wildlife casualties, then the locals who depend on income from tourism will lose their livelihood. People may then turn to farming to earn money, but crops require water to grow. This can place further strain on the water supply and worsen the original problem of the drought.”

Use examples to explain how the biosphere interacts with two other of Earth's spheres. Explain the interaction for each using complete sentences.
Answers
Answer:
The biosphere is influenced by other spheres and also influences other spheres.
The biosphere comes into contact with several other spheres such as the hydrosphere, the lithosphere, and the atmosphere.
Contact with the atmosphere is a two way street since the biosphere can alter the composition of the atmosphere. However, many members of the biosphere like mammals and birds depend on the mix of gases in the atmosphere to survive, and weather is an important agent of change.
The lithosphere is another sphere that can impact the biosphere through geologic activity both underground and on the surface. The impact of the biosphere on the lithosphere can be observed through the altering and transformation of terrains and through biochemical weathering of rocks.
