Photosynthesis Flashcards
Photosynthesis
1-Building sugars from CO2
2-Using the energy of light
The site of photosynthesis
Chloroplast
What is the highly specialized membrane chloroplast contain
Thylakoid Membranes
What light harvesting pigments do Thylakoid contain
Chliorophyll
2 major steps of photosynthesis
1-Light-dependent reactions
2-Calvin cycle
Light Dependent reactions
1- Happens in Thylakoids/chloroplast
2- Form high energy bond in ATP
3-Store high energy electrons as NADPH
Calvin Cycle
1-Happens in the stroma/Chroloplast
2-Uses ATP and NADPH which are provided by light-dependent reactions
3- Convert CO2 to sugar
4- happens only if light reactions produce ATP and NADPH
Stacks of thylakoids
Grana
Stroma
Liquid inside the chloroplast
Thylakoid membranes
Carry pigment to absorb light energy
Relationship between light reasction and calvin cycle
Light Reaction produce the ATP and NADPH required for Calvin cycle
Chlorophyll
the most abundant light-absorbing pigment in plants
what is Photosystems
when pigments are arranged into clusters in the thylakoid membrane
2 type of photosystems
1- Photosystem I (PS I)
2- Photosystem II (PS II)
Primary Product of Photosynthesis
1-Monosaccharides (Glucose and Fructose)
