- What are the roles of NADPH and ATP in the chemical stage of photosynthesis?arrow_forwardIn the photosynthesis lab, a group of students found that in the blue light condition, there was a change in absorbance (ΔA620) of 0.324 in extracted spinach chloroplasts. The students later went on a hike and located a plant they had never seen before and were interested in how the photosynthesis rates would compare to their experiment with spinach chloroplasts. They extracted chloroplasts of the unknown green-leaved plant and exposed them to the same experimental conditions as before. The students calculated the ΔA620 to be 0.100. Which plant (spinach or unknown) has the highest rate of photosynthesis? Explain your answer using evidence, being sure to demonstrate your understanding of the dependent variable.arrow_forwardWhich are the subproducts of the photochemical stage that are essential for the chemical stage of photosynthesis?arrow_forward
- What is the overall outcome of the light reactions in photosynthesis? NADPH and ATP molecules are produced during the light reactions and are used to power the light independent reactions. NADPH and ATP molecules are produced during the light reactions, which are used to power the light dependent reactions. Sugar and ATP are produced during the light reactions, which are used to power the light independent reactions. Carbon dioxide and NADPH are produced during the light reactions, which are used to power the light dependent reactions.arrow_forwardWhat is the equation for photosynthesisarrow_forwardDefine the following terms:arrow_forward
- If chlorophyll is extracted from plant cells and exposed to light, it absorbs light energy momentarily and this energy is almost immediately reradiated as light. Thus chlorophyll molecules can not cause photosynthesis by themselves. Why? What is required for photosynthesis to occur?arrow_forwardIn 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 C6H1206arrow_forwardWhich of the following best describes the products of the photochemical reactions of photosynthesis?A) NADH and ATP are made in the stromaB) NADPH and ATP are made in the stromaC) NADH and ATP are made in the thylakoid lumenD) NADPH is made in the stroma and ATP is made in the thylakoid lumenE) NADPH and ATP are made in the thylakoid lumenarrow_forward
- What is the general chemical equation of photosynthesis? Why doesn't that equation clearly show the real origin of the molecular oxygen liberated?arrow_forwardWhat are the two stages in Photosynthesis called and where in the chloroplast does each stage take place? What happens during each stage, what are the reactants and what are the products?arrow_forwardWhich molecule is responsible for the absorption of photic energy for photosynthesis? Where is that molecule located in the photosynthetic cells?arrow_forward
