Photosynthesis Pt. 2 Flashcards
factors that affect photosynthesis rates
Temperature Carbon Dioxide Light Intensity Pigments Available Duration of Light Amount of Chloroplasts
where in a plant photosynthesis takes place
Photosynthesis occurs in the mesophyll layer (the middle layer) —> cells —-> chloroplast —> thylakoid —> stroma
(thylakoid and stroma= 2 places= 2 steps)
the endosymbiotic theory, and how it relates to the chloroplast
Chloroplasts originated as photosynthetic cyanobacteria that was engulfed by an early eukaryotic cell.
chloroplast structure
Stroma- liquid part
Granum- stack of pancakes (thylakoids)
thylakoid- pancake
the energy involved in photosynthesis
endothermic reaction
how many phosphate groups do the energy transfer molecules involved in photosynthesis have
ADP- 2 phosphate groups
ATP- 3 phosphate groups
what makes glucose organic
Glucose is a carbohydrates (simple sugar) it contains carbon, hydrogen, and oxygen. This makes it a biological macro-molecule.
why plants use certain colors to perform photosynthesis
they use certain colors to perform photosynthesis because of the wavelengths.
the role of hydrogen ions
The hydrogen ions are sent into the thylakoids to be turned into ATP, they are then sent into the stroma where they release the energy and turn into ADP.
how is energy created using ATP
products of Light dependent
products: hydrogen ions/ O2/ ATP/NADPH
products of Calvin Cycle
products: starch/ADP/glucose/NADP+
how light dependent works
where does it occur, what molecule used, molecule:split discarded or rearranged, products
Light dependent occurs in the thylakoids, H20 is being used, H20 is split/discarded/rearranged–>O2 is discarded, Hydrogen ions are packing into the thylakoid and go through the ATP synthase through a “propeller” turning the hydrogen ions into ATP which is full of energy.
Objective Step 1
provides energy for step 2
Objective Step 2
make food
