|
-Describe electromagnetic radiation and theimportance of visible radiation to photosynthesis
-Describe structure of chloroplast and locationof photosynthetic reactions -Describe the light reactions of photosynthesisand how ATP and NADPH are made -Explain how plants are able to produce oxygenas a by-product of photosynthesis -------Explain the Calvin cycle and how ATPand NADPH are used to make G3P |

|
|
Reduction |
gain of electrons |
|
|
oxidation |
loss of electrons |
|
|
Photosynthesis |
-occurs in chloroplast -uses light (visible light is one type of electromagnetic radiation) -only about 5% efficient THE REST: -not the right wavelength -don't hit a pigment molecule in the plant -lost in conversion of ATP and NADPH to glucose |
|
|
Electromagnetic Radiation |
-Wave and particle components -Photons - particles of visible light -Plant pigments absorb specific wavelengths of light) -Photon absorbed means energy absorbed -Energy is used to "excite" an electron |
|
|
Light Reactions |
produce ATP and NADPH |
|
|
The Calvin Cycle |
synthesizes G3P |
|
|
Photosynthesis converts: |
-about 104.9 petagrams of carbon per year into biomass = 104.9 x 10^15 grams = 23.1 x 10^15 lbs = 23.1 quadrillion pounds |
