生命活动的基本单位（The basic unit of life activity） The first unit cell is the basic unit of life activity 1 basic features of biology: self-renewal, self replication, and self adjustment The 1.1 cell is the basic unit of organisms structure and function 1.2 metabolism is the basis of the organism for all life activities 1.2.1 includes material transformations (Synthesis and decomposition), energy conversion (storage and release) and information transfer 1.2.2 on the basis of metabolism, organisms exhibit stress, growth, development and reproduction, inheritance, and variation. 1.3 life is the product of the interaction between the environment and the environment 2 the material base of life 2.1 dozens of chemical elements mainly based on C, H, O, N, P and S The materiality of life; the identity of chemical constituents; the unity of the biological and non biological 2.2 any of various compounds that are mainly components of proteins nucleic acids and lipids 2.2.1 water - life comes from water as well as water The two existing modes and functions of water in cells; the relation between the content of bound water and free water and the metabolism of cells 2.2.2 inorganic salt The relationship between inorganic salt ions and metabolism (composition and regulation) 2.2.3 sugars - the major energy source for organisms to carry out life Starch, glycogen, C6H12O6, CO2H2O energy The important role of ribose, ribose, and cellulose 2.2.4 lipids Oxidation and energy supply characteristics of fats and sugars Relationship between phospholipids and various membrane structures of cells 2.2.5 all life activities are inseparable from proteins The chemical composition of proteins: amino acids - peptide chains - proteins A variety of biological functions of proteins: tissue proteins, enzymes, transporters, hormones, antibodies, proteins, etc. 2.2.6 nucleic acid is the genetic material of all living things Nucleotides - polynucleotide chains - nucleic acids (DNA and RNA) 3 the basic unit of lif
