Include the reactants and the products. Where does it occur? Light reaction is the changing of solar energy to chemical energy. Light and H2O is absorbed and ATP, NADH and O2 is the result. This all happens within the chloroplast.
Photosynthesis is the process where light energy is converted into chemical energy in the form of glucose. Its overall equation is: 6CO2 + 6H20 + light energy C6H12O6 + 6O2. The process of photosynthesis can be split into two reactions: the light-dependent reaction in the thylakoids and the light-independent reaction in the stroma. During the light-dependent reaction, light energy from the Sun is absorbed by chlorophyll (found in the chloroplasts in the leaf). This causes the excitation of two electrons, and they move to a higher energy level.
Photosynthesis and Cellular Respiration Daryl Waldron BIO/240 November 10, 2014 Tamu Crisden Photosynthesis and Cellular Respiration The cells of all organisms are capable in acquiring the energy necessary to fuel chemical reactions for growth, repair, survival, and reproduction. Photosynthesis and cellular respiration are the main pathways of energy flow in living organisms. Photosynthesis is a process by which plants and some other organisms convert, light energy from the sun, carbon dioxide from the air, and water from the earth into chemical energy stored in molecules like glucose. Cellular Respiration is the process in which glucose is broken down in the presence of oxygen to supply a cell with energy. In cellular respiration and photosynthesis, the reactants flow through pathways to become products in very different ways.
1. In the inner membrane of the mitochondrion, there is an electron transport chain. The membrane increases the surface area so a lot more copies of the chain can exist. Within the mitochondrion, there are ATP synthase that makes ATP out of ADP and inorganic phosphate. The ATP synthase is located inside the chloroplast for photosynthesis.
What provides the electron transport chain in cellular respiration with the energy it needs to function? 15. __________________________________________ (a process) Carbon-based molecules from food and oxygen are used to make ATP 16.What are the products of glycolysis? 17. Describe fermentation.
sugars because they all aldehydes. Different monosaccharides contain different number of carbon atoms. There are three types of monosaccharides, trioses, pentose and hexose. They generally contain three (trioses), five (pentoses) or six (hexoses) carbon atoms. Triose is used as a product in biochemical pathways of respiration and photosynthesis.
Plants are the producers for an ecosystem. They photosynthesise carbon dioxide and water and produce energy in the form of carbohydrates and other molecules. Photosynthesis requires water, and plants gain water from the soil using mineral ions such as nitrate produced by the nitrifying bacteria. Hydrolysis of ATP releases energy for processes such as active transport of the nitrate ions (and others such as potassium etc) from the soil into root hair cells, a process that lowers water potential and is used to draw water into the plant from the soil. In leaves, photosynthesis involves the photolysis of water, a process that involves the attachment of two electrons to a magnesium ion in chlorophyll and the production of hydrogen ions from the breakdown of water.
6 CO2 + 6 H2O + solar energy --> C6H12 + 6 O2 6) Be able to understand what the radish experiment shows us about photosynthesis. 7) How does light energy convert to chemical energy? Photons absorbed by chlorophyll Electron move to higher energy state Chlorophyll transfers electron to other molecule Chlorophyll can then accept an electron (from water) The energy gained by photo-excitation of chlorophyll is used to synthesize ATP This energy is then used to synthesize carbohydrates 8) Be able to recognize the formula for the reaction of respiration. C6H12O6 + 6 O2 6 CO2 + 6 H2O + energy 9) What is the difference between aerobic and anerobic respiration? 10) What is an energy pyramid and what does it represent?
(4) uses of energy in biological processes (B); active transport; muscle contraction; nerve transmission; synthesis; translocation; nitrogen fixation; receptors ENERGY TRANSFERS WHICH TAKE PLACE INSIDE LIVING ORGANISMS Living organisms including all plants and animals require energy for their cellular processes. In biological processes, the immediate energy source is often in the form adenosine triphosphate (ATP). The nucleotide ATP maintains both catabolic and anabolic reactions. An example of a catabolic reaction is respiration where large molecules are broken down into smaller ones with energy released. An example of an anabolic reaction is photosynthesis where small molecules are built up into larger ones using energy.
The different ways in which organisms use ATP All living organisms need energy in order to stay alive. Initially this energy comes from the sun. Plants use the sun’s energy in process called photosynthesis to produce complex organic molecules such as glucose, from water and carbon dioxide. A cell cannot get its energy directly from glucose. For this reason glucose is broken down in a process known as respiration; this causes glucose to release its energy which is then used to produce adenosine triphosphate (ATP).
