Document Summary
Concept review (focus on lectures 9 17) Many good videos under support materials (support anima5ons & videos) See summary video on photosynthesis & respira5on. Downloadable in support materials (from morris et al. , 2013) Enzymes as energy coupling devices and as catalysts. 1st & 2nd laws of. What is life: flow of energy, maser, informa5on, theme 1: energy flow basic thermodynamic principles. Coupling di erent energies: chemical, conforma5onal, metabolic, electrochemical gradient, theme 2: extrac5ng energy. Harves5ng reduced compounds: fermenta5on & respira5on, anaerobic respira5on. Harves5ng light light- dependent and independent reac5ons of photosynthesis. Membranes electron transport chains chemiosmo5c theory as selec5vely permeable barriers as energy producers as energy harvesters photosynthesis. Membranes are comprised of phospholipid bilayers: membranes are uid, fluid mosaic model. 2 l a t e l l e s s u. Proper5es of molecules that determine if they will cross a membrane: charge, size, hydrophobicity. Proper5es of lipids a ec5ng uidity: satura5on, sterols. X(out) (no direct energy input required)
