Chapter 4 - Carbon and the Molecular Diversity of Life

________ established a closed system in 1953 to simulate circumstances considered to have prevailed on early Earth at the time.

________ were supposed to exist exclusively in living creatures, which were regarded to have a life force that was not subject to physical or chemical rules.

In ________, a German scientist named Friedrich Wöhler attempted to make ammonium cyanate, an "inorganic "salt, by mixing solutions of ammonium ions (NH4 +) with cyanate ions (CNO-)

________ discovered a wide range of organic compounds found in organisms.

Proteins, ________, polysaccharides, and other molecules that differentiate living stuff from inanimate matter are all made up of carbon atoms that are linked to one another and to atoms of other elements.

________, a German scientist, attempted to create ammonium cyanate, an "inorganic "salt, in 1828 by combining solutions of ammonium ions (NH4 +) with cyanate ions (CNO-)

Compounds containing carbon are believed to be organic for ________, and their study is known as organic chemistry.

The ________ refer to organic molecules consisting of only carbon and hydrogen.

________ enters the biosphere via producers, which are plants and other photosynthetic organisms that utilize sun energy to convert atmospheric CO2 into ________- based molecules of life.

The ________ are utilized to demonstrate molecular architectural ideas that help explain why carbon is so crucial to life while emphasizing the notion that emergent characteristics emerge from the structure of matter in living creatures.

Both are steroids, which are ________ that share a carbon skeleton in the form of four fused rings.

________ may form bonds with four other atoms or groups of atoms, allowing for the formation of a wide range of compounds.
