Embedded in the thylakoid membranes Learning Objectives. 2. Compared to sugars such as glucose, carbon dioxide (CO2) is a low-energy chemical compound. It is a metabolic activity that occurs in the Chloroplast. A. cytoplasm, stroma B. mitochondria, cytoplasm C. stroma, cytoplasm D. thylakoid membrane, stroma You may need to download version 2.0 now from the Chrome Web Store. It is during these reactions that the energy from sunlight is absorbed by the pigment chlorophyll in the thylakoid membranes of the chloroplast. View photosynthesis worksheet (1).docx from BIOLOGY BIO 100 at University of the Philippines Mindanao. The light-dependent reaction of photosynthesis: The light-dependent reaction takes place at the thylakoid membrane. A. cytoplasm, stroma B. mitochondria, cytoplasm C. stroma, cytoplasm D. thylakoid membrane, stroma Light-dependent and light-independent reactions are two successive reactions that occur during photosynthesis. Mathematics, 17.09.2020 07:01. If you're seeing this message, it means we're having trouble loading external resources on our website. Certain objects, such as a prism or a drop of water, disperse white light to reveal these colors to the human eye. Answer Save. Photosynthesis represents the biological process by which plants convert light energy into sugar to fuel plant cells. The light-dependent reactions of photosynthesis The light-dependent reactions use light energy to produce the high-energy compounds ATP and NADPH, The chemical energy in these compounds is needed to synthesize organic compounds during the light-independent reactions. Photosynthesis process can be divided into two stages: Light Reaction. Light-independent reaction is also called the dark reaction or the Calvin cycle. Photosynthesis: Photosynthesis is a metabolic process in which energy from sunlight is used to synthesize carbohydrates like glucose. The light reactions of photosynthesis begin with the absorption of light by chlorophyll a and accessory pigments in the thylakoids. Introduction We will discuss only the light reaction of photosynthesis which produces these three types of molecules. This term is something of a misnomer, for these reactions can take place in either light or darkness. In plants, the light reactions take place in the thylakoid membranes of organelles called chloroplasts. The thylakoid membrane contains some integral membrane protein complexes that catalyze the light reactions. The Calvin cycle occurs: A. mostly in the dark. This energy is then transferred to chlorophyll molecules called P680 and P700, which form part of photosystem II and photosystem I, respectively. The light reaction of photosynthesis produces ATP and NADPH that collectively initiate Calvin’s cycle, and releases ADP, Pi and NADP+ that is again utilized by the cells to form high energy molecules in the light reaction. Formerly Peter S. Lv 7. If you're behind a web filter, please make sure that the domains *.kastatic.org and *.kasandbox.org are unblocked. If 4 are subtracted from twice a number, the result is 10 less than the number. Photolysis of water to provide the electron to the chlorophyll. ATP and NADPH are generated by two electron transport chains. Chlorophyll absorbs light energy and starts a chain of steps that result in the production of ATP, NADPH, and oxygen (through the splitting of water). The Calvin cycle occurs: A. mostly in the dark. 0 0. Photosynthesis begins with the light reactions. Chlorophyll and other pigments absorb energy from sunlight. 2 Answers. Here water is oxidised and carbon dioxide is reduced to carbohydrates. Formerly Peter S. Lv 7. 1 month ago. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Here, sunlight is converted to chemical energy in the form of ATP (free energy containing molecule) and NADPH (high energy electron carrying molecule). During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
