- A16 PHOTOSYNTHESIS
- overview
- photosynthesis occurs in the leaf where there's chloroplast
- 6CO2+ 6H2O = C6H12O6+6O2
- photosynthesis is a process of energy transformation in which light energy is firstly changed into electrical energy and then into chemical energy.
- LAW OF LIMITING FACTORS
- photosynthesis is made up of a series of small reactions. it's the slowest of those reactions that determines the overall rate of photosynthesis
- TEMPERATURE
- LIGHT INTENSITY
- CARBON DIOXIDE
- photosynthesis is made up of a series of small reactions. it's the slowest of those reactions that determines the overall rate of photosynthesis
- LIGHT-DEPENDENT REACTION
- PURPOSE: TO PRODUCE ATP+ SPLIT WATER
- SITE: THYLAKOIDS
- PHOTON OF LIGHT HITS THE CHLOROPHYLL PIGMENT
- THE PHOTON CAUSES AN ELECTRON TO BE EXCITED TO A HIGHER ENERGY STATE
- THE ELECTRON IS HELD IN AN ELECTRON CARRIER AND MOVES DOWN THE ETC- LOSING ENERGY THROUGH REDOX- ENERGY USED TO MAKE ATP
- ELECTRON LOST FROM PS1 REPLACED BY AN E FROM PS2
- EXCITED E FROM PS1 MOVES DOWN AN ETC AND USED TO PRODUCE REDUCED NADP
- ELECTRON LOST FROM PS1 REPLACED BY AN E FROM PS2
- THE ELECTRON IS HELD IN AN ELECTRON CARRIER AND MOVES DOWN THE ETC- LOSING ENERGY THROUGH REDOX- ENERGY USED TO MAKE ATP
- THE PHOTON CAUSES AN ELECTRON TO BE EXCITED TO A HIGHER ENERGY STATE
- PURPOSE: TO PRODUCE ATP+ SPLIT WATER
- LIGHT-INDEPENDENT REACTION
- SITE: STROMA
- CO2 COMBINES WITH RuBP
- COMBINATION PRODUCES 2X GP
- ATP+ REDUCED NADP FROM LDR USED TO REDUCE THE ACTIVATED GP INTO 2X TP
- NADP REFORMED AND GOES BACK TO LDR
- SOME TP CONVERTED TO ORGANIC MOLECULES MOST IS USED TO REGENERATE RuBP
- NADP REFORMED AND GOES BACK TO LDR
- ATP+ REDUCED NADP FROM LDR USED TO REDUCE THE ACTIVATED GP INTO 2X TP
- COMBINATION PRODUCES 2X GP
- overview
- adaptions of the leaf
- large surface area that allows the leaf to collect as much sunlight as possible
- thin- diffusion pathway is short
- numerous stomata
- transparent cuticle to let light through
- long, narrow mesophyll packed with chloroplasts
- arrangement of leaves avoids shadowing by other leaves
- air spaces in lower mesophyll to allow gas diffusion
