Document Summary
Biology of the cell (the university of british columbia) Biology of the cell (the university of british columbia) lomoarcpsd|14719499. Secondary active: primary active generates electrochemical gradient, co-transports other solute against [gradient] (ex. pump na+ to transport glucose) All organisms composed of cells, all cells come from other cells, cells are fundamental unit of life. Plasma membrane, uses metabolism to make energy, contains self-replicating blueprint. Euk have true nucleus, nuclear envelope, membrane- bound organelle, mitochondria, chloroplasts. Prok have nucleoid, circular dna, no organelles, small. All evolved from luca (prok 4b yrs, euk 2b yrs) Enthalpy: how strongly bonded a system is (more important for stability) Entropy: motional freedom of components in a system. **increasing entropy of water for the formation of phospholipid bilayer b/c e favourable, when phosphlipid float freely in water, interactions b/ w hydrophobic tails&water lowers its. 3d structure depends on nci b/w r groups. Liposome: purified lipids w/small heads, double tails, aqueous centre.
