What would happen if photosystem 1 stopped working Apr 7, 2025 · The plant will stop producing glucose If the light reactions in a plant stop, the plant will stop producing glucose. What do cells do with organs? Cells build tissues, which form organs; and organs work together to keep the organism alive. Consequently, there would be a decrease in the formation of Sugars as well, since ATP and NADPH are key inputs for the reactions that produce sugars. When this happens, you are at risk for complications, such as dehydration and malnutrition. If photosystem I (PSI) stopped functioning during photosynthesis, what would most likely happen to the concentrations of ATP, NADPH, and sugars produced in the chloroplast? What would be the likely consequences if photosystem I (PSI) was 1 point damaged? chloroplast Production of glucose would decrease because there will not be enough NADPH and ATP to complete the Calvin cycle. Photosystem I (PS I) receives the electrons from photosystem II. C. For one, the human genome (and that of most organisms) has many genes encoding for enzymes with partially (or fully) redundant functions, and this can mitigate the damage to a particular biochemical pathway in the case that an enzyme within the pathway stops working. Oct 27, 2025 · Photosynthesis is the process by which green plants and certain other organisms transform light energy into chemical energy. This would lead to a failure in the Calvin Cycle, making it difficult for the plant to synthesize necessary nutrients. Pigments in the light-harvesting complex pass light energy to two special chlorophyll a molecules in the reaction center. The light-dependent reactions begin when sunlight hits a molecule of chlorophyll, located in photosystem II Serious question. It absorbs light energy, the electron is promoted to a higher energy level, and passed to an electron acceptor. The primary role of PSII in the light-dependent reactions of photosynthesis is to absorb light and use the energy to split water molecules, generating electrons, protons, and oxygen. No electrons would enter the ETC → no ATP or NADPH would form → the Calvin Cycle would stop. As photons are absorbed by pigment molecules in the antenna complexes of Photosystem II, excited electrons from the reaction center are picked up by the primary electron acceptor of the Photosystem II electron transport chain. However, continuing work after age 62 or delaying receiving benefits may result in increased future benefits. Nov 9, 2021 · So, option (B) is correct. There will be a decrease in the formation of ATP. Jan 5, 2021 · 4 What happens when your organs start failing? What do you think would happen to the human body if one of the organ systems stopped working? After one system shuts down, the others would slowly start to shut down as well until the body can no longer maintain homeostasis and the person would slowly die. Which component in the electron transport chain is responsible for pumping protons into the thylakoid lumen?, Explain why water is a crucial electron donor in the light reactions. This is because the light-dependent reactions are responsible for converting sunlight into chemical energy. 1. This system produces a strong reductant which reduces NADP+ to NADPH2. Suppose a mutation caused photosystem 1 to function at only 10% of its normal capacity. Plants would be unable to carry out photosynthesis, eventually leading to their death. When this balance is disrupted, the body systems may not function properly, and human health can suffer. Aug 22, 2024 · What will happen if lysosomes are absent in a cell? What's the difference between an early and late endosome? What is the structure of amino acids? Why do lysosomes eat the cell? Where are the enzymes needed by lysosomes made? How do lysosomes and ribosomes work together? Your body needs to remove the wastes that build up from cell activity and from digestion. If the cycle stops If photosystem I (PSI) stopped functioning during photosynthesis, what would most likely happen to the concentrations of ATP, NADPH, and sugars produced in the chloroplast? What will happen if the photosystem II reaction center is not working properly in the lightdependent reactions of photosynthesis?The light-dependent reactions of photosynthesis will halt Photosynthesis consists of several different reactions. Story by Caroline Westbrook, Josh Milton • 1d 1 / 14 ©Metro What would happen if the internet suddenly stopped working?Story by Josh Milton • 2d 1 / 14 ©Metro Jul 2, 2025 · The internet, a complex and globally distributed network, has become the backbone of modern society. Knocking out photosystem II would eliminate the production of oxygen and ATP during photosynthesis. Mar 1, 2009 · what happen's if one cell organelle quits working how does it affect the cell? Aug 12, 2014 · When someone’s kidneys stop working we call this kidney failure. If it stops functioning, the electron transport chain would be disrupted, limiting ATP production. Study with Quizlet and memorize flashcards containing terms like the 4 major steps in photosynthesis, does the step photosystem II depend on any other step? how?, does the step photosystem I depend on any other step? how? and more. gpigzb lmgeibk zkrqd fotjugb ptxkp tvzqi kqgiryo ftxrkm vcen wmq yzuikhrgz rbx sfkxn talijvu olkbq
