3. Green fluorescent protein (GFP), native to jellyfish, is a biological imaging tool that emits bright green light at 509 nm. Three variant proteins have been developed that emit light at different wavelengths as shown below. a) What is the energy of the photons emitted by the green fluorescent protein? b) Rank the energies for the photons emitted by GFP and its variants. green fluorescent protein GFP >= 509 nm yellow fuorescent protein YFP > = 527 nm red fluorescent protein RFP > = 610 nm blue fluorescent protein BFP 7. = 457 nm

Answer questions 3 and 4
CHEM 110 Week 2 (Lesson 1) INSTRUCTIONS: Work in pairs to solve these problems. Use the Scribe's Worksheet to structure your work. Partners should take turns being the facilitator and scribe for the questions. Once you have the answer to a question, write it clearly on this page below the question. At the end of recitation, your TA will collect the work done on the Scribe's Worksheets. 1A. Which one of the interacting charges shown below will have the lowest electrostatic potential energy? Put them in order of electrostatic energy from lowest to highest. Which interactions are attractive? Which ones are repulsive? Recitation Worksheet I || ||| Review your answers. Discuss the connection between high/low energy and attraction & repulsion. Does high energy correspond to attraction or repulsion? Does low energy correspond to attraction or repulsion? 1B. Draw a plot depicting the interaction of a proton with an electron as function of distance. On the same graph, include a curve depicting the interaction of two protons as a function of distance. 2. A. Ammonium chloride (NH4CI) is added to a beaker filled with water initially at 25 °C. After the salt dissolves the final temperature of the mixture is 14 °C. B. Potassium nitrate (KNO3) is added to a beaker filled with water initially at 25 °C. After the salt dissolves the final temperature of the mixture is 42 °C. For both of these situations: i. Identify the system and the surroundings. HINT: for purposes of this question, you can summarize the process for both of these as salt(solid) → salt(solution) ii. Does energy go into the system or come out of the system? iii. Is this process endothermic or exothermic? 3. Green fluorescent protein (GFP), native to jellyfish, is a biological imaging tool that emits bright green light at 509 nm. Three variant proteins have been developed that emit light at different wavelengths as shown below. a) What is the energy of the photons emitted by the green fluorescent protein? b) Rank the energies for the photons emitted by GFP and its variants. green fluorescent protein GFP >= 509 nm Copyright 2011-2019 Chemistry Department PSU yellow fluorescent protein YFP >= 527 nm red fluorescent protein RFP >= 610 nm blue fluorescent protein BFP 7 = 457 nm 4. Silicon has three stable isotopes 28 Si (27.98 amu), 2⁹Si (28.98 amu), and 30Si (29.97 amu). If the abundance of 28 Si is 92.22%, what are the abundances of the other two isotopes?
