Photosynthesis

Basic Photosynthesis Write an equation with all the words in this picture.

Chlorophyll Pigments that absorbs light. Also… Carotene (orange) Xanthophyll (yellow) Anthocyanin (blue/purple)

Chlorophyll absorbs red and blue light, while reflecting green

Chlorophyll a vs. b They complement each other. Shade of green is dependent on ratio of a to b.

Intermission

Two Reactions Light Reaction Light Reaction Dark Reaction Dark Reaction Also known as Light Independent Reaction Also known as Light Independent Reaction Also known as the Calvin Cycle Also known as the Calvin Cycle

Light Reaction Occurs in the granum (on the thylakoid (in the lumen (where chlorophyll is))). Occurs in the granum (on the thylakoid (in the lumen (where chlorophyll is))). Light splits water to make oxygen, a proton, and ATP. Light splits water to make oxygen, a proton, and ATP. Equation: Equation: 12H 2 O + 12NADP + 18ADP → 6O NADPH + 18ATP

Light Independent Reaction Occurs in stroma Occurs in stroma ATP and H + are used to turn CO 2 into glucose. ATP and H + are used to turn CO 2 into glucose. Equation: Equation: ATP + NADPH + CO 2  C 6 H 12 O 6 + ADP + NADP

Starch Glucose is stored as starch (carbohydrate) Glucose is stored as starch (carbohydrate) Examples of starch include: Examples of starch include:
