(1) ATP & how it works
 * What is ATP (an energy Carrier)?
 * What gets continually attached and broken off?
 * Why?
 * Draw a cycle diagram to show this
 * Find a video to explain this better

ATP stands for Adenosine Triphosphate. ATP is a chemical compound that cells would use to store energy or to release energy. It is the basic source of energy. In addition, there is also a general term called ATP synthase which basically means an enzyme that can combine elements like adenosine triphosphate (ATP) and adenosine diphosphate (ADP) and inorganic phosphate by utilizing some form of energy.
 * What is ATP?**

The ATP molecule has three phosphate particles attached to it, hence the name 'Triphosphate'. This is it's state when it is 'carrying energy'. This term is in fact inaccurate, as ATP does not 'carry' or 'transport' energy at all. Instead, it follows a cycle, known as the ATP Cycle, through which is 'carries' energy from one place to another. The way this works is quite simple, really. The ATP molecule moves to the protein or organelle in need of energy, then, with the help of enzymes, it catabolizes (breaks up), and separates one of its phosphate particles. This reaction causes a huge amount of energy to be released, which can then be used in operate the organelle or protein. After loosing a phosphate, the ATP molecule is renamed to ADP, because it now only has two phosphates (Diphosphate). ADP then travels back to the mitochondrion or chloroplast, in order to 'pick up' enough energy to reattach that third phosphate. It is now fully charged again and can be reused as ATP. A diagram to explain this cycle can be found below:

If you are still confused by ATP, here is a great video that helps explain it very well. I found the above video slightly confusing, as it moved very fast through all the processes. Some of you may be familiar with Khan Academy on Youtube, as we used it in grade 8 in math. The tutorials are easy to understand, because it is all very step-by-step, he goes at a pace that everyone can understand. This video was also easy to understand because it describes ATP using the analogy of it being a sort of "currency". As we found from the Enzymes unit, using an analogy makes things easier to understand. media type="youtube" key="YQfWiDlFEcA" height="315" width="560"

What is ATP? Adenosine triphosphate: Stores, releases and supply energy for __cellular process__. it is used to transport energy inside the cell. ATP molecules consists __adenosine__ and three phosphate groups which is called __Triphosphate.__ Adenosine is formed when adenine is attacked to ribose. Adenines base using to form nucleoids of nucleic acids. This is also formed in DNA. In DNA, there are adenine (A), thymine (T), guanine (G), and cytosine ( C).

[] here is a link to that tells you the each parts of the ATP molecule **Functions of Adenosine Tri Phosphate.** The Triphophate is responsible for many functions inside the cells. Cell Structure Maintenance : Cell membranes are responsible for taking care of the cell and protecting the cell form the outside. For us humans, the cell membrane helps us guard against injuries and illness. When ever the cell membrane or any other structural part of a cell is restructuring, ATP molecules provides the energy necessary for the restructure. DNA Synthesis : living organisms all has DNA. The DNA contains all the information about each of the living organism. The physical traits, psychological traits and everything. Whenever DNA is synthesized (to produce substance by combining chemical precursors) inside of the human body, the energy required to do so is provided by the ATP molecules. Intra-Body Signals : humans are given signals from our brain all the time. How to react to each things, both physically and psychologically. For example, when you touch a hot pot, the signal instantly goes to your brain and tells you to get the hand off of the hot or when someone hits you, as soon as you feel the pain, the brain is already sending you signals. The energy need to send the signals are provided by the ATP molecules.
