ATP contains three phosphate groups. The third phosphate group (the outermost one) is called the alpha phosphate. The breaking of this phosphate bond is accompanied by the release of a large amount of energy which can be used to drive key steps in metabolic reactions.
With the removal of alpha phosphate, the remainder molecule is ADP

How much ATP energy is invested in glycolysis?
2 ATP molecules are invested during glycolysis per each glucose molecule that is being metabolized. The first ATP molecule intervenes in the very first step, that is: from glucose to glucose 6-phosphate, catalyzed by a hexokinase, releasing an ADP molecule. The second ATP molecule is used in the third step: from fructose 6 phosphate to fructose 1,6-bisphosphate, catalyzed by a phosphofructokinase, and releasing also an ADP molecule.
The energy of ATP becomes available to a cell when the molecule is what?
the ATP molecule is broken down
What are the 3 types of ATP in a molecule?
There is only one type of ATP and it is a molecule all of its own.
What molecule carries out the major amount of energy for the cell?
ATP or adenosine triphosphate, is involved in energy transfer.
What molecule must bind to to the cross bridge in order for it to disconnect with actin?
The molecule that binds to myosin, which causes it to disconnect, is an ATP molecule
What remains after the ATP molecule splits to release energy?
Go to the blood stream to drve the cells
How many ATP (net) are made in the glycolysis part of cellular respiration?
Glycolysis is a 10 step enzymatically catalyzed reaction which splits up a glucose molecule into two molecules of pyruvate. The process of glycolysis can occur in absence of oxygen. A net yield of 2 ATP is obtained at the end of gylcolysis for every molecule of glucose oxidized.

The ATP molecule is not used in?
The ATP molecule is not used in excretion process. This is a molecule that will be used in cellular respiration to store energy.
Explain the importance of phosphorylation in biochemical reactions?
Phosphorylation creates ATP (adenicine triphosphate) from ADP (adenicine diphosphate). ATP is the molecule needed to sustain our cells, and therefore our bodily functions.
What are the 3 types of ATP in a molecule?
There is only one type of ATP and it is a molecule all of its own.
Which part of the ATP molecule breaks free of the rest when an ATP molecule is used for energy?
the adenine
What molecule actually does the worm of life?
ATP
What molecule carries out the major amount of energy for the cell?
ATP or adenosine triphosphate, is involved in energy transfer.
What is the key component of the energy molecule ATP?
The key component of the energy molecule, ATP is the ribose.
Where happen the first step of cellular respiration?
Glycolysis, where 1 glucose molecule (C6H12O6) splits into 2 pyruvate (C3H6O3) and produce 2 ATP.
