Lecture 9: integrated metabolism 2 photosynthesis: ixing co2 into glucose, reducing it, giving it electrons: takes light, stoichiometrically balanced, co2 consumed, o2 evolved, measuring photosynthesis becomes harder in chlamy because we have integrated metabolism. Making co2, consuming oxygen, opposite gas exchange from cellular. Understand big picture, how does chlamy cell work? respiraion. Measure carbon ixaion: measure rate of photosynthesis: co2 analyzer measured co2 concentraion, if photosynthesis is working, co2 concentraion should drop, because we are ixing carbon in organic sugar, can adjust light intensity. 0 co2 ixaion, as these processes are in equilibrium the x value of light intensity that elicits a co2 ixaion rate of 0. Add compound that reacts with the product to produce a colour. Not product directly changing colour, but an indicator of the product being formed. This is temperature sensiive: measure disappearance of substrate. Graph shows increasing substrate concentraion: 10 reacion tubes, enzyme concentraion is constant, rate of enzymaic acivity is proporional to substrate concentraion.
