A. The C4 plant performs photosynthesis more efficiently than the C3 when the CO2 concentration is 600ppm or less. Provide one reason why the rate of photosynthesis doesn’t change for the C4 plant when the CO2 concentration increases above 400 ppm. B. Discuss what is happening in the C3 plant when the CO2 levels are below 50 ppm. Provide one reason why this does NOT happen to the C4 plant.

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.
Condition: A transmembrane (or integral membrane) protein that acts as a H+ channel has been added to the thylakoid membrane. What impact will thishave to photosynthesis? Explain why. (Specific values are not required, just an indication of overall effect and reasons why.)
Explain in detail of the stages of photosynthesis without explaining all the reactions of each pathways, but state the key steps of each pathway. Mention the location where each pathway happens in the plant and lastly make a table of the products formed at the end of the stage (ATPs, NADPHs, and water). Discuss about the oxidation-reduction of various molecules that are a part of these pathways.

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
Details For this assignment, draw and label a chloroplast. Indicate which step of photosynthesis occurs at each place and indicate the correct order with numbers (Use all of the following words in your labels: chloroplast, thylakoid, stroma, light dependent phase, and light independent phase.) Then write two complet sentences describing what happens at these two locations: one sentence for the thylakoid and one sentence for the stroma, including what molecules are used and what molecules are released.
Compare the light-dependent reaction with the light-independent reaction. Type of Reaction Description Location in Chloroplast Light-dependent Light-independent
Adjusting the wavelength of light and increasing the temperature can increase the rate of photosynthesis. Using specifics, describe in detail the effect of wavelength and temperature on photosynthesis and why or how these 2 factors affect the creation of the molecules used in or produced by photosynthesis.
d) In the presence of sunlight, an electrochemical gradient is generated between two of the spaces within the chloroplast. 1.Describe what happens when a photon of light energy hits a molecule of chlorophyl. 2. What is meant by the term electrochemical gradient? 3.What role does the photosynthetic electron transport chain play in the generation of the electrochemical gradient? 4. Two chemical reactions also contribute to the generation of the electrochemical gradient. What are the reactions, where do they occur, and why do these factors affect the gradient? 5. The electrochemical gradient can be utilised by ATP synthase to generate ATP - explain how the location and structure of ATP synthase enable it to perform this function. e) The light reactions of photosynthesis generate ATP and NADPH for use in the dark reactions (i.e., the Calvin cycle). Why are they needed?
