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

___ Involved in bonding
___ Positive charge
___ when gained or lost creates ions
___ Neutral charge
___ Found in nucleus
Answers
Answer:
E, P, N and P, E, P, E, N, N and P
Explanation:
I am pretty sure the answers would go like this (in the order you have here):
1. Electron (they have a negative charge)
2. P (The atomic number is determined by the number of protons)
3. N and P (The atomic mass is determined by how many Neutrons and Protons there are in the atom)
4. Electron (they are usually involved in bonding)
5. Proton (they have positive charge)
6. Electron (ions are created when an atom has gained or lost electrons)
7. Neutron (they are neutral)
8. Both Neutrons and Protons (they stick together inside the nucleus)
I am not entirely sure why the atomic number determination has 2 blanks since it is only determined by protons, but I hope this helps. I havent studied this for a while but those are the best answers I can provide and have checked them with my books so I hope they are correct. Good Luck!

2. What are the two major subdivisions of the nervous system, and what does each division do?
Answers
Answer:
2 Major Subdivisions:
Central Nervous System
Peripheral Nervous System
Explanation:
The central nervous system (CNS) regulates the majority of bodily and mental activities. It is divided into two parts: the brain and the spinal cord. The brain is the core of our ideas, the translator of our surroundings, and the source of control over physical action.
The PNS is the nerve that links the CNS to the rest of the body. The peripheral nervous system's principal job is to link the brain and spinal cord to the rest of the body and the outside world. The peripheral nervous system sends and receives information to and from the central nervous system. This is done by neurons that convey information from sensory receptors in the eyes, ears, skin, nose, and tongue, as well as stretch receptors and nociceptors in muscles, glands, and other internal organs.

what is the cell wall function and factory part or worker?
Answers
Answer:
Major cell parts function just like the structures and people who work together in a factory. Cells have strong cell walls and a cytoskeleton to keep their shape; the walls are made of fiber for protection just like a factory building has sturdy walls for support.
The cell wall serves as a protective and structural layer surrounding plant, fungal, and bacterial cells. It provides rigidity, support, and defense against external pressures and pathogens.
In various species, the cell wall serves as a robust outer layer. Its primary component in plants is cellulose, which helps to preserve cell structure, limit excessive water absorption, and promote growth. Chitin is found in the cell wall of fungi, providing both structural integrity and protection.
Bacteria have a variety of cell wall compositions; peptidoglycan, for example, is an essential part of many bacterial cell walls. Along with other cellular components, this "factory-like" part of the cell performs its functions. It is comparable to a factory's base, supporting the cell's framework, and worker, guarding against threats and preserving the cell's overall operation.

protein.
A type of RNA that is called as ribonucleic acid type called as transfer RNA that is used for the production of the amino acid at a time and the protein assembly takes place at the ribosomes.
What is the role of DNA and RNA for the sake of protein synthesis ?
DNA are responsible for the providing out the code for the cell's activities and the RNA are responsible for providing out the service to make them proteins.
Each group of 3 bases in the mRNA constitutes a codon and each codon is specifying a particular type of amino acid. The mRNA sequence therefore used as a template to make the assembly in order of the chain of amino acids which form a protein.
It is found that in all biological cells , usually occurs in cytoplasm of cell though its production takes place in nucleus. Whereas DNA is providing the code for cell's activities and RNA is responsible for converting that code into proteins which carry various cellular functions.

The abundance of sodium leak channels in skeletal muscle is ______ the abundance of sodium leak channels in a typical neuron.
Answers
The abundance of sodium channels in muscles is as important as the abundance of sodium leak channels in a typical neuron.
Sodium plays an essential role in the body, this includes important functions such as:
Intervening in the process of muscular contraction.Intervening in the process of interneural communication.This is possible through sodium channels in cells that allow sodium to enter or leave the cell at very specific times and this causes specific reactions in cells.
In neurons: Sodium channels are abundant and essential because due to the action of sodium signals are passed from one neuron to others.In muscles: Sodium channels are abundant and essential, especially in skeletal muscles. The role is sodium is to contract or relax muscles, which makes movement possible.Based on this, the presence of these channels in both neurons and skeletal muscles is equally important.
