Photosynthesis and Respiration
During photosynthesis, plants absorb sunlight and use that light to produce sugar , or glucose, used as energy for the plant. The beginning stage, the. Free Essay: The Cellular respiration and photosynthesis form a critical cycle of The second step of cellular respiration is the oxidation of pyruvate, which takes chemical conditions of its habitat and its relationship with other living things. The relationship between photosynthesis and cellular respiration is such that Cellular respiration uses glucose and oxygen to produce carbon dioxide and water. Stages, Light dependent Reactions – Light energy and water are used to.
Some cells respire aerobically, using oxygen, while others undergo anaerobic respiration, without using oxygen. The process involves a set of chemical reactions to convert chemical energy from the glucose molecules into ATP molecules. Oxygen plays no part during this stage, so it is called anaerobic respiration.
Aerobic Respiration This process takes place in specialized structures within the cell called mitochondria, and uses the products of glycolysis, the pyruvate molecules, to release energy, along with CO2 and water as the by-products of the reaction. The energy released is stored in the form of ATP molecules.
Usually, a total of 38 ATP molecules is produced. Differences between Photosynthesis and Cellular Respiration Photosynthesis takes place in two stages of the light reactions and the dark reactions.
Cellular respiration involves aerobic glycolysis and anaerobic respiration.
Photosynthesis and Respiration
Photosynthesis takes place only when there is sunlight. Cellular respiration occurs at all times. Photosynthesis takes place in plant leaves containing the chlorophyll pigment.
Cellular respiration takes place in the cytoplasm and mitochondria of the cell. Photosynthesis utilizes sunlight to produce food molecules. Ten enzymes are needed for the ten intermediate compounds in this process.

Two energy-rich ATP kick-start the process. Both types are energy-rich and used in other cell reactions.
In cells which use oxygenthe pyruvate is used in a second process, the Krebs cyclewhich produces more ATP molecules. Productivity of the cycle[ change change source ] Theoretically, 38 ATP molecules can be made per oxidised glucose molecule during cellular respiration two from glycolysis, two from the Krebs cycle, and about 34 from the electron transport chain.
Estimates are 29 to 30 ATP per glucose. They share the initial pathway of glycolysis but aerobic metabolism continues with the Krebs cycle and oxidative phosphorylation. Understanding Cellular Respiration Cellular respiration is a process in which water and carbon dioxide are produced through the break down of chemical bonds of glucose or the oxidizing of food molecules. Energy is released during cellular respiration and is captured as Adenosine Triphosphate ATP and then utilized by different cell activities that consume energy.
Aerobic respiration and glycolysis are the two main steps responsible for completely breaking down glucose into water and carbon dioxide. This process, at which point the pyruvate molecules created during glycolyis, breaks down further when there is oxygen and creates 34 ATP molecules.
This anaerobic catabolism of glucose produces two ATP molecules and two pyruvate molecules, and happens in all cells.
Cellular respiration - Simple English Wikipedia, the free encyclopedia
There are a few key differences between cellular respiration and photosynthesis. This process involves plants making food by using sunlight. In order to produce glucose, this process requires energy.ATP & Respiration: Crash Course Biology #7
This process occurs in some bacteria and in all plants. This process occurs within the chloroplasts, the chlorophyll-containing organelles inside a plant. In order to release oxygen back into the atmosphere and create sugar, this process requires water, sunlight, and carbon dioxide from the atmosphere. This process converts the food created by photosynthesis into energy which is then utilized by living organisms and plants.
