Chapter 7, Problem 2RQ
Summary Introduction
To explain:
The equation of photosynthesis.
Concept introduction:
Photosynthesis is the process by which light energy is captured and then stored as chemical energy in the bonds of organic molecules such as sugar. It is the most amazing process that provides not only fuel but also the oxygen required to use this fuel efficiently. In lakes, photosynthesis is performed by certain bacteria and on land mostly performed by plants. Photosynthesis in plants occurs in the chloroplast.

In order to summarize Photosynthesis reactions, draw FOUR big boxes in a line down the middle of your page.
Write 1) Photosystem II (water-splitting, 2) Photosystem I (NADH-producing), 3) Chemiosmosis and
4) Carbon fixation (Calvin) Cycle inside these boxes.
Below each process name write WHERE it occurs.
Make arrows going in and out of each box. Write IN and OUT on top of the page above the arrows.
Each box represent multi-step processes. You are focusing on the INPUTS and OUTPUTS.
A. First focus on the flow of ENERGY. For each box write the INPUT and OUTPUT - the molecule(s) or form that
contain the energy. Indicate if it is kinetic or potential energy.
B. Next, in a different color of ink (or highlighter) focus on the flow of ELECTRONS. For each box write the molecule(s)
that carry the electrons IN and OUT.
C. And finally, in a third color of ink (or highlighter) focus on the flow of CARBON. For each box write what molecule (if
any) carries the carbon IN and OUT.

- 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.arrow_forwardExplain the background of the experiment and briefly describe the procedure. When describing the procedure, be sure to include IV-the amount of carbon dioxide concentration and DV-the amount of oxygen produced. Explain the data we are collecting and why.arrow_forwardFor the following questions, choose one to discuss: chloroplast/photosynthesis State at the outset which one you will discuss. A) What role do proton gradients play in the process of photosynthesis proton gradients allow B) Where are proton gradients formed? Within what structures are they seen in chloroplasts How do the structures help them to maintain a gradient? C) Explain where and how the chloroplast or mitochondria uses passive transport and active transport to complete photosynthesis or cellular respiration.arrow_forward
- What is Photosynthesis? Write down the equation of photosynthesis?arrow_forwardYou performed an experiment on photosynthesis on Elodea, using bromothymol blue as an indicator forpH. Your two light conditions were red light and blue light. You found that in blue light, your solutionturned a nice cobalt blue, and in red light it turned green.a. What can you conclude about the efficiency of photosynthesis in Elodea regarding those twowavelengths?b. What would your conclusion be if your negative control (no Elodea in white light) turned greenalso?arrow_forwardWrite the overall net reaction for photosyynthetic Co2 fixation. (Take into account both light and cark reaction of photosynthesis?)arrow_forward
- What is photosynthesis? Describe the reactants and products inwords and in chemical symbols.arrow_forwardThoroughly explain all the steps of the light reaction of photosynthesis. Please also demonstrate using arrows what occur in each step.thank youarrow_forwardCan you please pick the right answer in each parentheses? In photorespiration ["oxygen", "NADH"] is consumed and ["nitrous oxide", "carbon dioxide"] is produced, and requires the activity of ["glycerate dehydrogenase", "the enzyme rubisco"] in the stroma of the chloroplast. Photorespiration ["decreases", "increases", ""] photosynthetic efficiency and is particularly prevalent under conditions of high temperature, found in more equatorial latitudes. Plants in these ecosystems have evolved to alter photorespiration, capturing carbon dioxide in the form of ["phosphoenolpyruvate", "oxaloacetate"] that is then converted to ["malate", "pyruvate"] used to regenerate CO2 and delivered to rubisco in the calvin cycle to achieve carbon fixation.arrow_forward
