Why Are You Alive - Life, Energy & ATP

In the few seconds you actually have lasted on the edge of life and death.You probably won't feel that your body is undergoing an incredible activities of these activities will never stop.Suppose you are a scroll down in the upward escalator spring toys.Part of representative cell division.Escalator represent push you forward principles of physics.Live is like a walk in, but what also can't.If you arrived at the top of the escalator, you won't slide down again, you will never dieGo to.A little disturbing is that the universe wants you to reach the top.
What do you do to avoid this kind of situation? And why are you still alive?All life is based on cells.Cell is different from the lifeless universe, it can perform voluntary activities.When reached the limits of life, the cells will be dismantled, back to space again.Unfortunately, the universe seems to want to let life be aborted.The universe doesn't want to let the world become wonderful, want to let all things is very boring.We call this phenomenon "drops", he is one of the basic principles of the universe.Very difficult to explain, it is hard to understand, we are again fine in another articleSaid.Now, you have to know living creature is exciting.Cell is made up of millions of such proteins and the water molecules.Occur into dry tens of thousands of times per second, cell divisions in the reaction and activities.Alive means cells must avoid itself drops continuously, to death.Cells must always be separated from the universe.One way is to keep the inside and outside the cells to different types, the extra molecules discharge cells in vitro.To do this, cells need energy.Energy can let the matter in the universe work, displacement, produce change, make a change.
Energy cannot be created, not destroyed, cosmic energy sum unchanged forever, we don't know why, but that is the case.In the hundreds of millions of years ago, the biggest challenge is to obtain available early cell energy.Early cells from a simple chemical reaction in chemical energy, in addition we don't know much they found the ultimate energy conversion systems: the building blocks of life, a molecule called adenosine triphosphate (ATP)Its molecular structure make receiving, releasing energy and convenient.When cells need energy, such as the need to rule out molecules or repair function, ATP cells decomposition, and using chemical energy to work or produce change, this is why living creature can respond.We don't know when and where the first ATP produced on the earth.But all creatures will use ATP or close to the ATP, to keep the internal functionJump.It for all plants, fungi, bacteria, and is vital to the survival of the animal, no ATP there would be no life on earth, it might be, also in the universe.Although the decomposition to produce chemical energy is very useful, but missed the early life of the biggest energy available:Solar energy.
The sun to fusion of atoms, releasing photons, the energy released into the solar system. But this kind of energy is original, not to absorb, must be refined.After thousands of years of evolution, has finally figure it out how to use the solar energy cell.It absorbs solar energy, and most of them into a can be used to sustain lifeLearning material.We call this process: photosynthesis.Will contain a photon of electromagnetic energy is used for molecular combination, electromagnetic energy into chemical energy, stored in the ATP molecules.Some cells so start making glucose, or sugar.Easy to decompose, more energy, also is quite good to eat. This process is very convenient, let many cells give up trouble of photosynthesisBy consuming other cells to obtain nutrients directly. Many people think that this is one of the largest in the history of betrayal.
After evolution continues to photosynthetic cells can only be collected on the surface of the energy, so the output is limited, restricted their channel evolution.With the passage of time, some cells sugar, other is responsible for the cell to gobble up.For millions of years of evolution degree is almost the same.Until one day, a cell ate another cell, but did not kill the cells.So, the two cells. It completely changed the future of the planet. The cells became the ancestor of all the animals on the earth.Whether it is the blue whale, deformation, dinosaurs, jellyfish, of xu or the monkey." Of course you are. These creatures can be traced back to this moment.The fusion of two creatures are very important, because the two fusion cells more powerful.Parasitic drag out an ignoble existence cells no longer, but focus on the production of ATP, it became the cells of plants: mitochondria.By focusing on host cell survival and provided food for the mitochondria.Mitochondria are actually reverse photosynthesis, is also very complex.It was obtained from other cells place of sugar, and oxygen and molecular precursor, produces ATP molecules are full of energy.This process is just like a melting pot, emit carbon dioxide, water and a small amount of kinetic energy (PS: it is your body temperature)
In a certain stage, the cells will be combined to form a community, and lead to multicellular organisms, eventually form you!Today, you are composed of trillions of cells, each cell has a lot of energySmall machines.Even if capacity process is interrupted for a few minutes, you will die.Since life is so fragile, stored ATP can is a good idea?As stored in fat and sugar can let us in a short period of time can live without breathing.If life to solve the obstacles of so much let you survive why life is so short?Simple organisms such as e. coli, in every division between 50 times the mass of the ATP produces them.
Your body need a lot of ATP to stay alive.Every day, your body produces 90 * 10 ATP node 26 points.And your weight, the production is so much to live one day, store it is impossible for a few minutes of ATP.Although ATP can quickly convert energy, but it is hard to store energy, because 1% of its energy only glucose molecules, the quality is 3 times as much,So ATP production of fast, consume faster.This is a simplified description of life, what makes you become the spring on the escalator.This is an extraordinary story, you need the molecule to survive, do not produce ATP means death.And you must own production, it is like driving a car at full speed at the same time, also must pick up roadside garbage production of gasoline.As far as we know, it all started in billions of years ago.A small part of the dead universe breeds life, can sustain itself and development.The spring toy leap as always, from the first cell to you is reading this article.At some stage, you will again and the dead of the universe, you might and its description of your adventures.But in the end you can appreciate the beauty of life, let the dead of the universe, full of fun.
