Photosynthesis is a chemical process whereby plants and algae that contain chlorophyll capture radiant energy from the sun, and use carbon dioxide and water from the environment to then convert the sunlight to food (glucose), while at the same time creating oxygen and water as byproducts. Carbon dioxide produced during respiration is one of the reactants plants need to perform photosynthesis. 6.13). Photosynthesis is a process through which the glucose is produced from carbon dioxide and water in the presence of chlorophyll and sunlight. Without photosynthesis, the carbon cycle could not occur, oxygen-requiring life would not survive and plants would die. Photosynthesis produces the oxygen to replenish oxygen that is used up by living organisms during respiration. Below is an image of a worksheet I use in my Biology classes to help students learn the ATP Cycle to mastery. Right click the image below to download the worksheet. Photosyn­thesis (photos-light, synthesis-putting together) is an anabolic process of manufacture of organic com­pounds inside the chlorophyll containing cells from carbon dioxide and … Photosynthesis is essentially the only mechanism of energy input in the living world. photosynthesis and the step from organic molecules to CO 2 as cellular respiration. Photosynthesis is important to living organisms because it is the number one source of oxygen in the atmosphere. =The role water plays in the process. The response earned 1 point for in part (a) for explaining that cellular respiration converts glucose into … During respiration, oxygen combines with glucose to produce water and carbon dioxide. In photosynthesis, there are two structures that are responsible for the actual conversion of light to chemical energy; they are respectively named photosystem I and II. During photosynthesis, plants use carbon dioxide and water to produce sugars and oxygen. Animals do not make their own food from energy in sunlight. Ans ; Question: 5) Why are there two electron transport chains (ETO'S) in photosynthesis? The process of photosynthesis is essential in plants as it is responsible for deriving energy from light to be used by the plant to grow and reproduce. Please explain. Photosynthesis is the process by which plant cells convert light energy from the sun into chemical energy, so as to create energy-rich carbohydrate molecules like glucose. Cellular respiration is the process of breaking down food molecules to obtain energy and store it in the form of adenosine triphosphate (ATP) molecules. ATP and NADPH are used in the dark reactions to power the synthesis of sugar. (Opts) Be sure to include the following in your answer =What is produced in each and (briefly) how it is produced =What the source of electrons is for each ETC. Fill it out as you watch the YouTube video "ATP and ADP: Chemical Energy for Cells" and explain what is happening in each step. Please explain. Photosynthesis and cellular respiration are both part of … The process of photosynthesis is similar to that of C 4 plants but instead of spatial separation of initial PEPcase fixation and final Rubisco fixation of CO 2, the two steps occur in the same cells (in the stroma of mesophyll chloroplasts) but at different times, night and day, e.g., Sedum, Kalanchoe, Opuntia, Pineapple (Fig. The two stages of photosynthesis are linked by the ATP and NADPH produced in the light reactions.
