PHOTOSYNTHESIS

Photosynthesis

? Involves the Use Of Light Energy to convert Water (H20) and Carbon Dioxide (CO2) into Oxygen (O2) and Carbohydrates (sugars & starches)

? Goal of photosynthesis is creating glucose ? Glucose is a monosaccharide

? One Molecule of Glucose Stores 90 Times More Chemical Energy Than One Molecule of ATP

Pigments

? In addition to water, carbon dioxide, and light energy, photosynthesis requires pigments (molecules that absorb light).

? Chlorophyll is the primary light-absorbing pigment in autotrophs.

? Chlorophyll is found inside the chloroplasts in the thylakoid membrane

Electromagnetic Spectrum

? Visible Light Contains A Mixture Of Wavelengths

? Different Wavelengths Are Seen As Different Colors
