Which part of the light-independent reactions would be affected if a cell could not produce the enzyme RuBisCO?
Name: How Do Chloroplasts Capture Energy from the Sun? Plant cells and some algae contain an organelle called the chloroplast. The chloroplast allows plants to harvest energy from sunlight, a process known as photosynthesis. Specialized pigments in the chloroplast absorb sunlight and use this energy to combine carbon dioxide and water to make glucose and oxygen. The complete reaction is: 6CO2 + 6H,0 → C;H12O6 + 602 9, Raw Materials (Reactants) CO, = carbon dioxide H,O = water Products CH,,O6 = glucose О, 3 охудеn Plant cells can use this process to manufacture glucose, a simple sugar. Some of the glucose is used immediately for cellular respiration, where it is converted to a high energy compound called ATP. You might recall from studies of the cell, that the process of creating ATP occurs in the mitochondria. Glucose that is not used right away is packaged as carbohydrates or fats and then stored in the roots, seeds, and fruits. All autotrophs can make their own food in this way,…
I. How Does Light Intensity Affect the Rate of Photosynthesis? Procedure: The purple slider can be used to change the light levels. You will count the number of bubbles at each level. The timer in the square box can be used to measure 30 seconds. Otherwise, a data is provided below for your reference. Light Intensity Number of Bubbles (30 0 sec) 40 45 50 20 | 25 15 11 18 24 31 36 42 47 50 10 30 35 7 c. Oxygen produced by the plant d. CO2 produced from photosynthesis 30. Based on the light test, as you increase the intensity of light, the rate of photosynthesis 29. What does the bubbles represent? a. CO2 consumed by the plant b. Photosynthesis occurred a. Increases b. Decreases c. Stays the Same d. None produced

MODIFIED TRUE or FALSE. Circle Tif the statement is correct and F if the statement is otherwise. Then, use the blank provided to correct the underlined word/phrase. 13. T F Increasing light intensity decreases the rate of photosynthesis. Carbon dioxide molecules enter the light-dependent reactions from the atmosphere. 14.T 15.T F Photosynthesis uses energy from ATP and high energy electrons from NADPH produced in the light-dependent reactions to make glucose in the Calvin cycle. . 16. T F The light-dependent reaction produces ATP, NADPH, and carbon dioxide. ATP synthase spins like a turbine as H' ions pass through it to generate ATP. 17.T 18. T Electrons are energized twice during photosynthesis.
