  • Photosynthesis 264 gm CO2 + 216 gm H2O + 192 gm O2
  • Photolysis = Ce- & Mn ++
  • H + acceptor in hills rectangle (Hillis oxidant) = Hill՚s oxidant, Ferricyanide, Ferric oxalate, Quinone, 2,6 dichloride indophenoe
  • Low redox potential – lose e- - e- donor e- move from low ⇾ high
  • High redox potential – gain e- - e- acceptor e- move from low ⇾ high
  • Chl respiration for light absorption in photosynthesis
  • NADPH + H + produced in light rectangle Constitute assimilatory power.
  • Photosynthesis efficiency increment in intermittent light
  • Chl is Oxidized & e- acceptor is reduced
  • PS I – P700, stromal & Grana, chl a, b carotenoids
  • PS II – P680, grana, chl a, b, c, d, carotenoids (chl b is more abundant)
  • Cyclic photophosphorylation use light energy to build ATP
  • Photorespiration – O2 is competitive inhibitor of CO2 fixation, C2 plants, energy consuming light dependent uptake of Co2 & output of CO2
  • C4 plants – chloroplast is dimorphic, Kranz anatomy by Dowton & Treguna, inner ring called as starch rich chloroplast
  • Lack grana called bundle sheath cells
  • CO2 cone is very high & RUBICO participates
  • On lowering temperature – C4 Photosynth xeric habitat
  • Wasbury effect – inhibitory effect of high concentration of O2 on photosynthesis in C3 plants, due to competition between CO2 & O2 for public C4 are insensitive to such change.
  • CAM pathway – CO2 us fixed at night & make glucose during day, in cactus etc. , Calvin cycle CAM separated in time stored as u – c malic acid.
  • Law of limiting factor – when biological process is condition as to its rapidity by number separate factors, rate of process limited by the slowest factor.
  • in terrestrial plants called C13 discrimination (C4 has from C23 then C3 plants sugar from sugar cane (C4) is sweeter than sugar beet (C3) plants)
  • Photosynthesis = anabolic, endergonic, Oxidative – reductive
  • Destruction of chlorophyll due to high light intensity = Solarization most common limiting factor of photosynthesis = CO2.
  • Compensation point – photosynthesis = respiration
  • D eMU (di-chloro phenyl dimethyl urea) – O2 release
  • C3 plant – more CO2 is released in light than dark phase & increment with increment of CO2
  • Chlorophyll unit in leaves of difference ages plants = assimilatory power it decrement with age of plant.
  • 12 + help in translocation of food = active process
  • Presence of labelled sugar in phloem showed that solutes are transport through phloem.
  • If tree ringed, roots die 1st, ringing not successful in monocot open Vascular bundle
  • Ringing done below fruits – fruits will be bigger in size.
  • Ringing done between fruits & leaves – fruits will be smaller in size
  • CO2 concentration is more before sunrise (start of photosynthesis) So CO2 + H2CO3 lower pH
  • Photo excitation Occurs in chl. molecules
  • Protochl converts to Chl (in presence of C7 & C8 of same pyrrole ring (IV) and + 24 atoms)
  • Jenner – against smallpox
  • Pasteur – against rabies.
  • Infective nature of TMV – merger
  • Contagium vivum fluidum – Beijerinck.
  • More diversity found in genome of virus.
  • M. Schlesinger isolated virus bacteriophage WLL made of protein H3PO4
  • Vision – Fully assembled mature particle of virus capable of infection.
  • Smallest virus = coli phage F2
  • Smallest plant virus = Tobacco necrosis virus.
  • Longest plant virus = Citrus Trist age virus.
  • Smallest animal virus = foot & month disease of cattle.
  • Largest animal virus = pore – parrot fever virus.
  • Arboviruses = Arthropod borne virus Reovirus – Respiration enteric orphan virus.
  • Capsomere are proteinaceous (Each present in protomere)
  • Capsomere highly synthesis structure which can be crystallized
  • Total capsomere = 10 (n – 1) 2 + 2 n = number of capsomere on one edge Example-Adenovirus (6 = n) so total = 252
