which statement best describes photophosphorylation?

Water molecules are formed here. B) The excitation is passed along to a molecule of P700 chlorophyll in the photosynthetic unit. Through photophosphorylation, the energy from the sun is also used to make ATP from ADP. Photophosphorylation is the conversion of ADP to ATP using the energy of sunlight by activation of PSII. It involves … This type of photophosphorylation usually occurs in the thylakoid membrane. the answer is lactic acid from anaerobic respiration. It depends on the surface of the levels. Explanation: que81hhh. This involves the splitting of the water molecule in oxygen and hydrogen protons (H +), a process known as photolysis.Subsequently, a continuous unidirectional flow of electron from water to PSI is performed (Fig. Photophosphorylation True or false? Which best describes the respiratory system? C. They are lipoproteins. c) Cyclic photophosphorylation occurs in the cytochrome bf … it is the flow of hydrogen ions down a concentration gradient. 2. Which statement describes the process in chloroplasts that is most similar to the process shown ... photophosphorylation to create an electrochemical gradient The respiratory system allows for gas exchange, water and heat balance, and creation of sound and speech. Only two sources of energy are available to living organisms: sunlight and reduction-oxidation reactions. The surface area of the leaf influences its performance to In which locations do each of these events occur? This means that the genotypes of these individual organisms are passed on to the next generation. It produces keratin in the body. b) Cyclic photophosphorylation reduces NADP + to NADPH. Production of ATP within the living system occurs in many ways. as autotrophs these organisms are able to obtain energy through photosynthesis. Photosynthesis is the process by which organisms that contain the pigment chlorophyll convert light energy into chemical energy which can be stored in the molecular bonds of organic molecules. As cells divide, different daughter cells eliminate unneeded DNA and replicate needed DNA. Oxidative phosphorylation and photophosphorylation are two major mechanisms that produce most of the cellular ATP. During this process not only glucose is produced, oxygen is also released into the atmosphere as a by-product of this process. A) chloroplasts B) grana C) stroma D) ferredoxins . Each nucle... protist eukaryotes that are not plants, animals, or fungi ("misfits")... Answer: transform boundary. ... What are the products of linear photophosphorylation? In mitochondria, chemiosmosis translocates protons from the matrix into the intermembrane space, whereas in chloroplasts, chemiosmosis translocates protons from the stroma to the thylakoid space. When the log of the number of cells is plotted versus the generation, the graph is linear. a. D) Only P680 is directly involved, not P700. B) A proton gradient allows hydrogen ions to flow back into the cells through transmembrane protein channels, releasing energy that is used to generate ATP. 73) 74) In mechanism, photophosphorylation is most similar to A) the Calvin cycle. Photosynthesis is possible thanks to the existence of special molecules, called photosynthetic pigments, capable of capturing light energy. It produces hormones in the body. a. Its once-strong services sector is in steady decline. Question 5 . 13) Which of the following statements about photophosphorylation is FALSE? In photosynthesis … it is the process by which light energy is captured to form simple sugars using water and carbon dioxide and to release oxygen gas as a byproduct. Which statements describe industry in the Piedmont region? The respiratory system allows for gas exchange, heat balance, and secretion of hormones. good luck!Explanation:... After pollen grains land on the stigma, a pollen tube grows from the pollen grain, through the style, and into the ovary. photosynthesis through the amount of light captured by it which is needed for Which statement describes thylakoids?A. Oxidative phosphorylation is a process involving a flow of electrons through the electron transport chain, a series of proteins and electron carriers within the mitochondrial membrane.This flow of electrons allows the electron transport chain to pump protons … As well chlorophyll which enables the leaf to absorb It is the process of synthesizing energy-rich ATP molecules by transferring the phosphate group into ADP molecule in the presence of light. However, Which statement about bacterial growth is true? It is the addition of a phosphate group to ADP to form ATP using light energy absorbed … It takes place during the light dependent phase of photosynthesis when energy from sunlight is captured by chlorophyll that converts it into chemical energy in the form of ATP and NADPH. D) It requires CO 2. Cyclic photophosphorylation occurs in both aerobic and anaerobic conditions. Question sent to expert. Photophosphorylation is of two types: Cyclic Photophosphorylation Which statement best summarizes what you have learned about substrate and enzyme binding and how it affects the function of enzymes?A. By using this site, you consent to the use of cookies. Glucose the the principle product of photosynthesis is synthesized in the dark reaction by CO2 fixation. answer choices ... decrease because the increase in temperature will prevent photophosphorylation. E. They are consumed in the chemical reaction. As living organisms, plants need energy to survive. Arasan. Natural selection is a mechanism of evolutionary change in which the organisms that are best able to survive are those that will leave the most offspring. light and be processed. b. • Which one of the following statements BEST describes the relationship between photosynthesis and respiration? The chemiosmotic hypothesis states that the synthesis of ATP generates a proton gradient that leads to electron flow through an electron transport chain. Solar energy constitutes not only the immediate energy force for green plants and other photosynthetic autotrophs, but also the energy source for almost all heterotrophic organisms, through the action of the food chains of the biosphere. 1. A. a. During this process electrons are exchanged between molecules, which creates a chemical gradient that allows for the production of ATP. Question: 29) Which Of The Following Statement Best Describes The Relationship Between Photosynthesis And Respiration? And millions of other answers 4U without ads. chlorophyll is broken down by oxygen to produce glucose . 11) Which of the following is the best definition of oxidative phosphorylation? Save. Given the statements, "a square root of 16 is 4," and "a square root of 9 is -3," complete the following blanks with the correct truth-values. Eating food provides fuel and building blocks for your body how food molecules reach the body’s cells and fuel cellular respiration. Only photosystem II functions here.D. Which term describes stacks of thylakoids? In eukaryotic cells, glycolysis takes place in the mitochondria. [Carbon dioxide] + [water] + [energy] produces [glucose] and [oxygen] Thylakoid enables the light-dependent reactions to occur b/c it has the photosystems. Glucose is formed here.B. Which statement best describes photophosphorylation? BOX 1 describes the ligand specificity and expression of TLRs in different cell types. C. photosystems I and II are both required. It is the conversion of light energy to chemical energy. Factors that are needed are water, CO2 and sunlight. In the process of photosynthesis, the phosphorylation of ADP to form ATP using the energy of sunlight is called photophosphorylation. Which of the following statements about cyclic photophosphorylation is correct? b) Cyclic photophosphorylation reduces NADP + to NADPH. chromosomes absorb carbon dioxide to produce protein .
