Photosynthesis involves the use of energy from sunlight, water and carbon dioxide to produce glucose and oxygen. While in photosynthesis carbon dioxide and water yield glucose and , through the respiration process glucose and oxygen yield carbon dioxide and water. The green pigment called chlorophyll is responsible for this conversion process. Electron Transport Chain In photosynthesis, the electron transport chain occurs at the beginning of the process, but it comes at the end of the process in cellular respiration. 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. In contrast, there are four metabolic stages happened in cellular respiration, which are the glycolysis, the citric acid cycle, and the oxidative phosphorylation. As you can see, … the are both really abig cycle.
The photosynthesis-cellular respiration relationship also explains why the two are necessary for the presence of life on the planet. The mitochondrion also has two membranes, the outer membrane and the inner membrane. Fermentation anaerobic respiration 2 points - metabolic process that converts sugar to acids, gas, or alcohol. Cellular respiration uses glucose and oxygen to produce carbon dioxide and water. What are the stages of Photosynthesis? Glycolysis- which occurs in the cytosol.
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. The chloroplast is made of grana, thylakoid, and stroma. The light reaction comes about in the thylakoid membrane and then switches light energy to chemical energy. Photosynthesis takes place in the chloroplasts, distinctively using chlorophyll, the green pigment implicated in photosynthesis. Without it, life on Earth would cease to exist.
The anaerobic reaction is also called fermentation. What are the Differences Between The Two Processes? Although both processes are found in double membraned organelles, photosynthesis occurs in chloroplasts in plant cells and cellular respiration occurs in the mitochondria of animal cells. Photosynthesis is a system in plants that takes the sun's energy and creates food mainly glucose. Cellular respiration occurs in the mitochondrion of the cell and photosynthesis occurs in the chloroplast. Two phosphates from the cytoplasm are added to the glucose.
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. Additionally, cellular respiration uses food to harvest energy, while photosynthesis uses light energy. The substance gaining electrons is referred to as the oxidizing agent and is considered reduced. The light independent phase takes place in the stroma and makes glucose by making carbon bonds. Cellular respiration depends on oxygen as a substrate 2. Prokaryotes may use either photosynthesis or cellular respiration, but since they lack the complex organelles, they produce energy in simpler ways. Krebs or Citric acid cycle occurs in the mitochondrial matrix of the cell.
At the end of the respiratory chain, oxygen accepts electrons and protons to generate water H2O. Oxygen and carbohydrates are absorbed in the process. Both reactions transform energy in one way or another - either storing it or releasing it. Essay Sabid Quddus 723 Cellular Respiration is the process that allows organisms to use the energy stored in glucose. In photosynthesis light dependent reactions, ultra violet light strikes chlorophyll pigments which excites electrons leading to separation of oxygen molecules from carbon dioxide.
This process occurs in the cytosol. Photosynthesis converts the light energy obtained from the sun into chemical energy of sugar and oxygen, whereas cellular respiration is a biochemical process by which cells obtain energy from the chemical bonds of food molecules. Cellular respiration has a lot of facts, as well. In Cellular Respiraton there are 3 phases and an Intermediate step. Photosynthesis and cellular respiration are both part of a mutually beneficial relationship. To emphasize this point even more, the equation for photosynthesis is the opposite of cellular respiration. Unlike photosynthesis, it works day and night.
Knowing how photosynthesis is related to cellular respiration will help you understand why these two biochemical reactions are important for survival of life on the Earth. They undergo a series of chemical reactions to produce carbohydrate molecules. Despite the differences between these two processes, there are some similarities. Rest of the features are, I think, opposite to each other. Carbon dioxide and water are absorbed. The chloroplast contains chlorophyll a green chemical is responsible for the green colour of the leaves. Glycolysis breaks glucose into two molecules of pyruvate.
