Describe the Four stages of the hypothesis for the origin of life on earth?
Abiotic synthesis of organic molecules: Simple organic molecules were formed from inorganic compounds under early Earth conditions. Polymerization: These organic molecules polymerized to form larger molecules like proteins and nucleic acids. Formation of protocells: These molecules self-assembled into protocells, which were the precursors to modern cells. Development of self-replicating molecules: Self-replicating molecules emerged within protocells, leading to the evolution of life on Earth.
Which organic molecules are NOT built from monomers?
Organic molecules that are not built from repeating monomers typically include simple molecules like water (H2O) and carbon dioxide (CO2), as well as complex molecules such as cholesterol and certain hormones. These molecules do not follow a polymerization process like monomers linking to form polymers.
What elements are presented in any molecule described as 'organic'?
Organic molecules contain carbon atoms, often bonded to hydrogen, oxygen, nitrogen, sulfur, and other elements. These molecules are typically found in living organisms and are the basis of biological processes. Organic molecules can be simple (like methane) or complex (like proteins and DNA).
Miller and Ureys apparatus was designed to demonstrate that life on Earth might have originated from?
Miller and Urey's apparatus was designed to demonstrate that life on Earth might have originated from inorganic molecules and simple chemical reactions occurring in the early Earth's atmosphere. Their experiment produced a variety of organic molecules, including amino acids, which are the building blocks of life.
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.
Where do simple carbohydrates come from?
Organic molecules
What changes complex molecules into simple molecules?
respiration and microbial degradation of organic matter

Miller and Urey observed the abiotic synthesis of?
Miller and Urey observed the abiotic synthesis of organic molecules, such as amino acids, by creating a laboratory simulation of early Earth's atmosphere and conditions. Their experiment demonstrated that simple organic compounds could be formed from inorganic precursors in a prebiotic environment.
What are molecules with carbon?
Molecules containing carbon are known as organic molecules. These can include simple compounds like methane and ethanol, as well as complex structures like proteins and DNA. The versatility of carbon allows for a wide variety of organic molecules to exist.
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.
The first person who proposed that small organic molecules could have arisen by chemical evolution of simple inorganic molecules was?
Aleksander Oparin
What molecules are produced by autotrophs?
Autotrophs produce molecules such as glucose through photosynthesis, which is their primary source of energy. They can also produce other organic molecules such as lipids, proteins, and nucleic acids necessary for their growth and metabolism.
How did the results of the miller Urey experiment change over time?
The Miller-Urey experiment showed that simple organic molecules, including amino acids, could be formed from inorganic precursors under conditions simulating early Earth. Over time, subsequent research and alternative experiments have further supported the idea that the prebiotic synthesis of organic compounds is plausible, contributing to our understanding of the origins of life on Earth.
What are two possible sources of simple organic compounds on the early earth?
Carbon and Nitrogen were most likely the the first two possible sources of simple organic compounds on earth as a result of exploding stars.
