Scene 2 (7s)
[Audio] Focus Question What do lettuce plants need to survive?.
Scene 3 (14s)
[Audio] New Vocabulary thylakoid granum stroma pigment NADP+ Calvin cycle rubisco.
Scene 4 (23s)
[Audio] Review Vocabulary carbohydrate: an organic compound containing only carbon, hydrogen, and oxygen, usually in a 1:2:1 ratio.
Scene 5 (35s)
[Audio] Overview of Photosynthesis Most autotrophs make organic compounds using photosynthesis. Photosynthesis converts light energy into chemical energy. The products and reactants of photosynthesis are identified in the overall chemical reaction for photosynthesis: 6CO2 + 6H2O C6H12O6 + 6O2 light.
Scene 6 (56s)
[Audio] Overview of Photosynthesis Photosynthesis occurs in two phases: In the light-dependent phase, light energy is captured and converted into chemical energy. In the light-independent phase, molecules formed during the light-dependent phase are used to make glucose..
Scene 7 (1m 15s)
[Audio] Phase One: Light Reactions The absorption of light is the first step in photosynthesis. Once light energy is captured, two energy storage molecules, ATP and NAPDH, are produced..
Scene 8 (1m 31s)
[Audio] Chloroplasts are organelles that capture light energy. They contain two main compartments: Thylakoids: flattened saclike membranes Stacks of thylakoids are called grana (singular: granum). Stroma: fluid-filled space outside the grana.
Scene 9 (1m 53s)
[Audio] Chloroplasts Photosynthesis occurs inside pigmented organelles called chloroplasts..
Scene 10 (2m 5s)
[Audio] . Watermill - Wikipedia.
Scene 11 (2m 11s)
[Audio] . Visualizing Electron Transport fr«n Lsed to a a MP. MP ATP.
Scene 12 (2m 18s)
[Audio] Phase One: Light Reactions Pigments Light-absorbing colored molecules called pigments are found in the thylakoid membranes. Different pigments absorb specific wavelengths of light..
Scene 13 (2m 34s)
[Audio] Electron Transport large surface area = large number of electron transporting molecules. Photosystems - special systems containing pigments that capture light..
Scene 14 (2m 47s)
[Audio] Electron Transport (continued) Light energy excites electrons in photosystem II and causes a water molecule to split. Next, the excited electrons move from photosystem II to an electron acceptor molecule..
