photosynthesis. They capture light energy to conserve free energy in the form of ATP and reduce NADP to NADPH. (tb) The rate at which photosynthesis happens can be measured using a dye (DCPIP)‚a Hill reaction‚ and a spectrophotometer. ( DCPIP ) 2‚6-dichlorophenolindophenol is a compound that is often used as a redox dye. Oxidized DCPIP is blue‚ DCPIPH‚ which is reduced by a single electron‚ is pink‚ and fully reduced DCPIP is colorless. It is often used in measurements of the electron transport chain

After experimenting from 1915 to 1921 with additive color systems that filmed and projected the two color components simultaneously‚ rather than in rapid alternation (thereby eliminating Kinemacolor’s color flicker and false color fringes around rapidly moving objects)‚ Dr. Herbert Kalmus‚ Dr. Daniel Comstock‚ and mechanic W. Burton Wescott (who left the company in 1921) developed a subtractive color print process for Technicolor. As in their final additive system‚ the camera had only one lens but

white or yellow t-shirts are all ok and don’t seem affected by the heat. Have you ever thought what might cause this to happen? Well the color of our clothes is determined by a chemical dye that is added to the cloth at the factory when it’s being made. Now the energy of sunlight affects the atoms of the dye in 2 different ways. Now we know how electrons react when light is shining on the atoms. These electrons absorb a specific frequency of light and become “excited”‚ and emit a specific frequency

many procedures that are very precise. This lab is broken down into five different sections; we will be using the Biuret Test for amino groups present in proteins. The Iodine Test to identify the presence of starch. The Grease Spot Test and the Sudan Dye test to identify the presence of lipids (fatty acids). The Benedict’s Test to identify the presence of reducing sugars. In the biuret test if the test result for protein changes a color of lavender‚ purple or pink‚ the test result for protein is positive
