Other literary records can be found in 4th century writings, by Palladius, who was an American agriculturist. Archaeologists have found seeds in Roman forts in Britain, so it is believed that the Romans are responsible for spreading raspberries throughout Europe.
Medieval History of RaspberriesBy the Middle Ages, wild berries were widely known and used as a food, as well as for medicinal purposes. Their juices were sometimes used in art, for paintings for example.King Edward I of England - He made raspberries famous and encouraged their cultivation throughout Great Britain
In these times, only the rich could afford raspberries!
King Edward I (1272 - 1307) is credited for encouraging cultivation of raspberries, which underwent a fast increase in popularity and availability.
American Conquest and Modern HistoryDuring the American conquest, settlers found several tribes of Native Americans already using and eating berries of all kinds. In particular, they used to dry berries to carry them in their nomadic travels.Meanwhile, British gardens were blessed with plenty of berries and bushes, and by the 18th century cultivations were widespread in all the regions of Europe.
When settlers brought with them European seeds, several new species and hybrids were cultivated in America, and the first commercial nursery plants were already being sold in 1771, by William Price.
In 1761, even George Washington started cultivating berries in his Mount Vernon estate. By 1867 there were over 40 known varieties, and after the Civil War, commercial production was commenced on a large scale, especially in the regions of Oregon, New York, Michigan, Pennsylvania, Ohio, Washington, Indiana, Illinois.
Cultivation increased steadily from 1880, when there were approximately 2,000 acres, to 1919 (54,000 acres). Growth continued through 1948 when berry cultivations reached 60,000 acres.
Today, in the USA, most raspberries are produced in Washington (60% of the total USA production) with 70 million pounds/year. Other important regions are Oregon and California.
The energy change of a molecule breaking into its constituent atoms is likely endothermic. This means that it takes energy to break these bonds.
the energy released in respiration is channeled into molecules of ATP.
Energy is released in most of the cases, except for a few.
Some bonds break, and two or more molecules result.
atomic energy
Adenosine triphosphate, abbreviated ATP. The molecule contains adenosine and three phosphate groups. When the cell needs energy, the bond between the second and third phosphate groups breaks, and the energy released is used by the cell to do work.
ATP is adenosine triphosphate which is energy unit for the body it store energy in phosphate bonds to use in time the bond breaks one phosphate released giving ADP adenosine diphosphate and energy
Potential energy
Photons are not oxidized. They are energy. A photon may be captured by an atom or molecule resulting in a change to the state of atoms.
When a fuel is burned, it is a combustion reaction. This reaction breaks apart chemical bonds and releases the energy stored in them.
when you break the bonds of the glucose molecule you get energy.
the adenine
adenosine triphosphate
It travels into the muscle cell. The cells break down glucose to produce energy in a process called Respiration. Glucose is a hydrocarbon molecule which contains energy in the bonds. To realease as much energy as possible the molecule must be completely broken down the constituent molecules (carbon and hydrogen) have oxygen addd to them, making CO2 and water.
As temperature is increased the kinetic energy of the constituent particles of matter increases.When temperature decreases the kinetic energy of them decreases. This is because temperature, or rather heat, is itself energy

ADP (Adenosine diphosphate) Technically, ATP breaks into ADP and a molecule of inorganic phosphate.
ATP,energy is stored mainly between bonds between phosphate groups
ATP (adenosine triphosphate), or ultimately it would be glucose.
energy molecules that breaks down into energy when needed by the body
Protein molecules change shape when you heat them. Then energy from cooking breaks some of the chemical bonds in the protein and this allows the molecule to take a different shape. This gives the food a more edible texture. The change is irreversible. It is called denaturing.
The potential energy of the molecules change during a reaction.
