Opioids are a type of drug. They are also referred to as narcotics. In the human body, the opioid receptors are present at a variety of locations, including the brain, in the spinal cord, on peripheral neurons, and the digestive tract. They often act as pain relievers.

Glycolysis is a series of reactions that extract energy from glucose by splitting it into two three-carbon molecules called pyruvates. Glycolysis takes place in the cytosol of a cell, and it can be broken down into two main phases: the energy-requiring phase and  the energy-releasing phase. Each three-carbon sugar is converted into another three-carbon molecule, pyruvate, through a series of reactions. In these reactions, ATP molecules and one NADH molecule are made. Because this phase takes place twice, once for each of the two three-carbon sugars, it makes four ATP and two NADH overall.

2 molecules of ATP is utilized during the conversion of glucose into fructose 1,6 diphosphate.

Substrate-level phosphorylation is the direct transfer of phosphate group to ADP to form ATP. It accounts of 100% of the ATP formed by the reactions of glycolysis. The first substrate-level phosphorylation occurs when 1, 3 - diphosphoglyceraldehyde is converted to 1, 3 - diphosphoglyceric acid and 2 NADH$ _2$ are formed, that is 6 ATP are formed. The 1, 3-diphosphoglyceric acid is then dephosphorylated to 3 phosphoglyceric acid producing 2 ATP via substrate-level phosphorylation. The second substrate-level phosphorylation occurs when phosphoenolpyruvic acid is converted to pyruvic acid producing 2 ATP molecules.

During cellular respiration, the energy formed in mitochondria is stored in the form of ATP which is also known as energy currency of the cell. It provides energy for all the life activities by its breakdown into ADP and Pi. ATP contains three phosphate group which has high energy bond. On the hydrolysis of ATP energy is released and ADP formed.

Adenosine triphosphate (ATP) is known as the energy currency of the cell. There are three phosphate bonds which store a large amount of energy. When these bonds are broken down, the energy is released. The energy is used to carry out biochemical reactions in the cell.

ATP is known as energy currency of the cell and it is a nucleotide formed by the combination of adenine as a nitrogenous base, ribose sugar, and triphosphate. It is found in free cells which breaks to form energy by breaking its high energy phosphate bonds. Karl Lohmann was first to discover ATP. It is produced by the mitochondria in the cell.

Adenosine triphosphate is a nucleotide also known as the energy currency of the cell that stores the energy in the form of phosphate bonds. When this bond breaks energy releases.

ATP means Adenosine Tri Phosphate, is a energy rich ribonucleoside. It is similar to ribonucleoside.

ATP is the energy currency of our body produced by the oxidation of food in the cell. ATP is utilized to proceed different metabolic process. Active transport is the movement of molecules across a cell membrane in the direction against the concentration gradient i.e., moving from an area of lower concentration to an area of higher concentration with the involvement of energy in the form of ATP.
