Document Summary

The cell: cell simplest entity that can exist as an independent unit of life. Metabolism: metabolism chemical reactions by which cells convert energy in order to break down molecules. Carbon: life"s chemical backbone: organic molecule carbon-containing molecules. Carbon has the ability to form 4 covalent bonds, due to its 4 unpaired e-. This ability, spatial orientation of the bonds, & e- ability to rotate freely contributes to structural diversity of organic molecules. Carbon can form links with other carbon atoms to form long chains or rings (from 2 carbons at the ends or within a chain). 2 adjacent atoms can form a double bond when sharing 2 e-: isomer molecules with same molecular formula but different structures. Cell wall: turgor pressure force exerted by eater pressing against an object; hydrostatic pressure, maintains structure (plants) Key cellular functions: replication of dna, synthesis of dna (transcription, assembly of ribosomes in nucleus; site of protein synthesis.
