Explain how photosynthesis and respiration are linked in order to provide you with energy from the food you eat. The carbon dioxide produced during respiration is released from the body and absorbed by plants to help provide the energy they need for growth and development. While the process of cellular respiration can occur regardless of the time, some parts of photosynthesis can only occur in daylight Conclusion In conclusion, we can summarize that both photosynthesis and cellular respiration are processes, which organisms use to obtain energy. Photosynthesis is a two part process which includes photophosphorylation light reactions and carbon fixation dark reactions. Photosystem I optimally absorbs photons of a wavelength of 700 nm. Photosynthesis the process by which plants, bacteria and some fungi that use energy from sunlight to produce sugar.
On the contrary, photosynthesis occurs in green plants, which contain chlorophyll and uses sunlight and water to convert it into energy. What remains are electrons and hydrogen ions electrically charged particles of hydrogen. Photosynthesis course of normally occurs in algae, vegetation and some micro organism. They are in reality the same reactions but occurring in reverse. Contrast and compare an absorption spectra versus an action spectra for Ps. Occurs in plants, protista algae , and some bacteria.
Photosythesis is the process in which light energy is converted into chemical energy to produce glucose. The citric acid cycle occurs in the mitochondrial matrix, which completes the breakdown of glucose by oxidizing a derivative of pyruvate into carbon dioxide. This process occurs in light sunlight only and so-called as light-energized oxidation process. Carbon dioxide produced during respiration is one of the reactants plants need to perform photosynthesis. These organisms are moreover generally known as as photoautotrophs. Conclusion From the above article, we can say that both the biological process are in mutually beneficial relationship, where from one process photosynthesis oxygen is liberated, which is used in another process cellular respiration and in return the carbon dioxide is released from the cellular respiration process, which is used up in the photosynthesis.
Hence in photosynthesis you have the light dependent reactions and the dark reactions while in respiration there is. These two have similarities and differences, too. The light reaction which occurs in grana of the chloroplast. Photosynthesis involves a set of chemical reactions, where Carbon dioxide and water are converted and released as glucose and oxygen to the atmosphere with the help of light energy. On the other hand, photosynthesis is an endothermic process, as energy is stored or utilised and is in the form of glucose or chemical energy, used during the dark reaction. Photosynthesis vs Cellular Respiration Photosynthesis and cellular respiration are both cellular processes organisms use to obtain energy.
While photosynthesis requires energy and produces food, cellular respiration breaks down food and releases energy. H+ gradient across thylakoid membrane into stroma. Photosynthesis produces the oxygen to replenish oxygen that is used up by living organisms during respiration. Formation of acetyl CoA 3. Secondly, other reactions occur in the presence of oxygen, and this is the reason they are skipped. Fermentation anaerobic respiration 2 points - metabolic process that converts sugar to acids, gas, or alcohol.
Therefore we can say that these two processes are one of the essential elements of maintaining life on the Earth. Both photosynthesis and cellular respiration are the main pathways of energy transportation in organisms. If plants take carbon dioxide and expel oxygen, and most other living things take in oxygen and expel carbon dioxide, the importance of both systems working in unison is obvious. This takes place in the plant cells that contain chlorophyll, the pigment within plant leaves that give them their green color. It is alleged to be the first course of by which a cell of residing organisms emits chemical vitality to fuel cellular train.
This process usually occurs in the cytosol and mitochondria of eukaryotic cells. All other organisms, including animals, have evolved to utilize some form of cellular respiration. So overall reaction where carbohydrates C6H12O6 are formed during photosynthesis is defined in the equation. At this moment we will consider the difference between the two essential and energy providing reactions to the living cells, where one is cellular respiration and another is photosynthesis. It occurs in structures called chloroplasts, which contain chlorophyll.
In aerobic cellular respiration oxygen is utilized to convert organic compounds into energy and in anaerobic respiration converts organic compounds into energy without using oxygen. Photosynthesis takes place only in green plants, algae, and certain bacteria which contain chlorophyll whereas cellular respiration occur in almost all organisms in mitochondria of eukaryotic organisms and in cytoplasm of prokaryotic organisms including autotrophs. However, while photosynthesis stores the energy in form of sugar and starch, cellular respiration breaks down organic compounds such as sugar and starch to obtain energy. Although this process is restricted to green plants and few bacteria only. Plants Photosynthesis occurs in the leaves of plants with little to none in the stems. After this, electrons are passed to the electron transport chain through 1438 Words 6 Pages - Cellular Respiration Assignment - 1. The potential energy is converted into the kinetic energy.
