Firefly luciferase is the enzyme that allows fireflies to illuminate their abdomens. Because this light generation is an ATP-requiring reaction, firefly luciferase can be used to test for the presence of ATP. In this way, luciferase can test for the presence of life. The coupled reactions are luciferin+O2 ⇌ oxyluciferin+light ATP ⇌ AMP+PPi, ΔGo=−31.6 kJ/mol If the overall ΔGo of the coupled reaction is -8.70 kJ/mol, what is the equilibrium constant, K, of the first reaction at 27oC?
In 1770, Joseph Priestley performed a series of experiments to determine the reactants and products of photosynthesis. The diagram below shows the experimental conditions and results of two experiments performed by Priestley, named here as Experiment 1 and Experiment 2. From his experiments, Priestley concluded that plants restore to the air whatever breathing animals and candles remove. Joseph Priestly Photosynthesis Experiments and Results Experiment Results: - candle extinguished (went out) 1 - mouse died Experiment 2 Results: candle continued to burn mouse stayed alive Note: Experiment 1 and Experiment 2 were both performed in the presence of sunlight. The substance produced by the plant in Experiment 2, that keeps the candle burning and the mouse alive is O CO2 O 02 O H2O O C6H1206
You will create a slide show/ Canva/ Website on the flow chart of photosynthesis phases .Your poster should include, but is not limited to:○ The overall equation is at the top.○ A diagram of a chloroplast which indicates where each reactant is used and whereeach product is synthesized. ○ All intermediary steps were studied in the light-dependent reactions and light-independent reactions, in the form of a flow chart(try to add details around them), using appropriate terminology. ● You will also submit a detailed explanation of your flow chart, using appropriateterminology.
A substantial amount of energy is put into the photosynthetic electron transport to extract electronsf from water and to elevate the energy level of ferredoxin to a very strong reductant. The amount of energy in one NADPH is 218 kJ.mol-1. What is the percentage of this energy conserved in NADPH for the production of one mole of oxygen? What happened to the rest of the energy?
