Document Summary
Rna associated with making proteins: 4 of them: dna a, t, c, g, strung together they form our genes in our chromosomes. Genes serve as blue prints to synthesize proteins. 23 pairs of chromosomes in most cells: some dna encode housekeeping genes, other dna encode cell specific genes. Chemical reactions and enzymes: reacting two or more substances yielding products or break apart substances to yield products, a + b c + d. Products: enzymes involved in chemical reactions and they allowed the reaction to occur. W/o oxygen: synthesize aerobic pathways lots of atp. Body organization: cell the primary unit of life, exhibit qualities of living things, human cells were together interdependence, we have 100-200 different cell types. In adult human 37. 4 to 200 trillion cells in our body: properties, all have cell membranes. Some cell membranes associate with organelles: organelles give function to cell. Some have membranes: nucleus, endoplasmic reticulum (one job is to make proteins), mitochondria.
