Document Summary
Plant cells and bacteria have a cell wall surrounding the plasma membrane. Further limits passage of molecules into/out of the cell. Plant cell walls composed of complex carbohydrates: Other polymers embedded into the cell wall. Can be surrounded by gelatinous polysaccharide layers (glycocalyx) Gram positive bacteria: thick peptidoglycan which prevents the stain to wash out. Gram negative bacteria: thin peptidoglycan which washed out the stain. Dna chromatin (made up of dna coiled around histones) chromosome. Double membrane around nucleus with nuclear pores. Only found adjacent to nucleus in animal cells. A bound pair of centrioles, surrounded by a shapeless mass of dense material called the pericentriolar material. Specialised dna structure that link 2 chromatids. Inner and outer mitochondria membranes separated by aqueous intermembrane space. C6h12o6 + 6o2 6co2 + 6h2o (+ atp) Harness energy from c-based fuels by oxidative phosphorylation. Generate and metabolise reactive oxygen species and free radicals. Golgi apparatus: protein processing, sorting and secretion.
