color change occurs: Combining chemicals can change the pigmentation that gives the chemicals color. A change in the pigments will cause the light to reflect differently and a color change to occur. Testing for pH is an example of a color changing reaction. The pH of the solution will change the pigment on the litmus paper or in the indicator. Acids and bases change the pigments in different ways‚ which causes the indicator to change different colors depending on the pH. A precipitate is formed:

Then splits and forms 2 3-carbon molecules b. Rubisco i. Most abundant molecule on earth ii. Catalyzes reaction above c. Carbon dioxide in Calvin cycle i. Gets into chloroplast – many ways ii. Algae – diffuses through membranes from surrounding water iii. Plants – carbon dioxide comes through stoma (pores) in leaves 1. These pores is where oxygen escapes into atmosphere (produced in the light reactions) E. Reduction

Essay During the Light Dependent Reactions‚ activity occurs within the thylakoids of the chloroplast. NADP+ accepts two high energy electrons and an H+ ion and then converts into NADPH. This process ultimately traps some of the sunlight in chemical form. Then‚ NADPH is able to carry the energy it absorbs to the rest of the cell. The reaction produces O2 gas and converts ADP to ATP and NADP+ to NADPH. First‚ pigments in Photosystem II absorb light‚ which is then absorbed by electrons‚ which are then passed

A Tour of the Cell Overview: The Importance of Cells • All organisms are made of cells. o Many organisms are single-celled. o Even in multicellular organisms‚ the cell is the basic unit of structure and function. • The cell is the simplest collection of matter that can live. • All cells are related by their descent from earlier cells. Concept 2 Eukaryotic cells have internal membranes that compartmentalize their functions Prokaryotic and eukaryotic cells
