Two hypotheses about the source of organic molecules on Earth would be, first, that they formed out of the original chemical composition of the planet, because of the energy provided by solar radiation and lightning, and second, that they were already present in interstellar dust clouds and therefore were part of the original composition of the Earth when it condensed out of an interstellar dust cloud.
What else can I help you with?
Before 1828 it was believed that organic compounds could be made only by a?
process called vitalism, which suggested that living organisms had a special force that allowed them to create organic molecules. However, in 1828, Friedrich Wöhler successfully synthesized urea from inorganic compounds, disproving the theory of vitalism and opening the door to the field of organic chemistry.
Energy used in the formation of the first organic molecules is thought to have come from?
Organic molecules form out in nature all the time by various energy sources. Organic molecules (such as amino acids and nucleobases) are found in meteorites, and many organic molecules (sugars) are found even in interstellar space.
Which compounds were classified as organic compounds according to th early chemists?
Early chemists classified organic compounds as those that were derived from living organisms, such as plants and animals. They believed that organic compounds could only be synthesized by living organisms and could not be produced in the laboratory through inorganic processes. This definition was later expanded with the development of organic chemistry to include compounds based on carbon, regardless of their origin.
What did single celled organisms need in order to increase the amount of energy they could produce by breaking down organic molecules?
O2
What are the following is an organic molecule?
An Organic Molecule was made of common elements, like Carbon, Hydrogen and Oxygen. These molecules were washed into sea to form pools of Organic Matter. As timed passed these molecules formed long and complex molecule chains. Slowly these molecule made themselves more advanced in different functions of their body from reproduction. They kept reproducing mutating complex molecules until these molecules developed into the first cells. These cells developed into the first cells without nucleus. Cells without nucleus are now considered to be the first types of microorganisms. So people could say that a organic molecule is the the 'reign' of Microorganisms.
2 places on earth where organic molecules could have been synthesized?
it's between A. amino acids or B. monosaccharides C.fatty acids or D.phospholipids
Where could Earth's early organic molecules have been synthesized?
In the atmosphere, in the upper layers of waters, basically everywhere where there's enough of the component elements, energy and convection available.Note that recent observations in astronomy have shown massive amounts of organic molecules to be present about newly formed star systems, so it's very well possible that some organic molecules were transported to Earth by comets, etc.
What is the first organic compound to be synthesized in lab?
The first organic compound to be synthesized in a lab was urea by Friedrich Wöhler in 1828. This marked a significant milestone in chemistry as it disproved the idea of vitalism, which proposed that organic compounds could only be produced by living organisms.

How could RNA have become involved in the mechanism for protein translation?
natural selection favored RNA molecules that synthesized catalytic proteins
The first person who proposed that small organic molecules could have arisen by chemical evolution of simple inorganic molecules was?
Aleksander Oparin
Molecules of life are also called organic molecules because?
When the field of organic chemistry was just beginning, it was widely believed that such chemicals were special in some sort of semi-supernatural sense and that only living things could make them due to a semi-supernatural ability they had that could never be duplicated naturally by man in the lab.This was gradually shown to be false as one after another of the organic chemicals were synthesized in the lab. Now we can even synthesize chemicals as complex as DNA in the lab (although once synthesized we often use living bacteria to mass produce it for us to reduce the costs).However the term organic chemistry stuck. There is now a new term biochemistry relating specifically to the chemistry of living things.
What is a hypothetical four stage sequence for how life could have first developed on Earth?
firstly small organic molecules formed from simple molecules.secondly these small molecules joined together into proteins and nucleic acids.thirdly molecules that could copy themselves such as RNA provided a way for molecular information to be inherited.fourthly,various organic molecules such as RNA and polypeptides formed "pre cells"
What statement is true of Oparin and Haldane's theory?
Oparin and Haldane's theory proposed that chemicals in Earth's early atmosphere could have formed organic molecules, leading to the origin of life on Earth. They suggested that simple organic molecules could have then combined to form more complex molecules like proteins and nucleic acids.
Energy used in the formation of the first organic molecules is thought to have come from?
Organic molecules form out in nature all the time by various energy sources. Organic molecules (such as amino acids and nucleobases) are found in meteorites, and many organic molecules (sugars) are found even in interstellar space.
What did Stanley miller prove?
He didn't really "prove" anything. He demonstrated that if you take carbon dioxide, water vapor, and ammonia, and zap it with an electric current for a week or so, you form sludge which contains all kinds of interesting organic compounds. This is fairly important conceptually, because it showed that using simple, purely physicochemical (that is, NOT biological) processes on very simple molecules it was at least possible to make reasonably complicated organic molecules.
Which compounds were classified as organic compounds according to th early chemists?
