Photosynthesis and cellular respiration are two key processes that sustain life on Earth. Both processes are essential for the survival of plants and animals, and they are interconnected in several ways. However, they are also quite different in many aspects.
Photosynthesis is the process by which green plants convert light energy from the sun into chemical energy stored in the form of glucose. It occurs in the chloroplasts of plant cells, and it requires the presence of chlorophyll, which absorbs light energy and converts it into chemical energy. During photosynthesis, carbon dioxide and water are combined using energy from the sun to produce glucose and oxygen. The glucose is used by the plant for energy, while the oxygen is released into the atmosphere as a byproduct.
On the other hand, cellular respiration is the process by which cells convert the chemical energy stored in glucose and other organic molecules into usable energy in the form of ATP (adenosine triphosphate). It occurs in the mitochondria of cells in both plants and animals. There are two main types of cellular respiration: aerobic respiration, which requires oxygen, and anaerobic respiration, which does not. Aerobic respiration is the most efficient and produces the most ATP, but it also produces carbon dioxide as a byproduct.
One of the main differences between photosynthesis and cellular respiration is the source of energy. Photosynthesis relies on light energy from the sun, while cellular respiration relies on the chemical energy stored in organic molecules. Another difference is the products of each process. Photosynthesis produces glucose and oxygen, while cellular respiration produces ATP and either carbon dioxide (aerobic respiration) or lactic acid (anaerobic respiration).
Despite these differences, photosynthesis and cellular respiration are interconnected processes. The oxygen produced during photosynthesis is used by cells during cellular respiration, and the glucose produced during photosynthesis is used as a fuel for cellular respiration. In this way, the two processes support each other and are essential for the survival of plants and animals.
In conclusion, photosynthesis and cellular respiration are two important processes that sustain life on Earth. While they are quite different in terms of the source of energy and the products of each process, they are interconnected and support each other in maintaining the balance of life on our planet.

Occurs only in phototrophs all green plants, algae and some bacteria. Mader, 2010 … Cellular Respiration vs. Glucose is synthesized in the Calvin-Benson cycle. Similarities between Photosynthesis and Respiration Despite the difference between photosynthesis and respiration, both processes are interdependent. You need energy just to think, breathe and pump blood through your body. Supplying energy to the cells they carry out is the main process called life. Conclusion This is all about the meaning, explanation, and difference between photosynthesis and respiration.
compare and contrast photosynthesis and cellular respiration
Both photosynthesis and cellular respiration start with one type of energy and convert it to another, but the types involved are different. Photosynthesis does not occur without cellular respiration because the relationship between photosynthesis and cellular respiration is such that the products of one system are the reactants of the other. The tiny compartments where photosynthesis occurs are called chloroplasts, using a pigment called chlorophyll, which makes the plants green. In respiration, electrons are given out by the hydrogen carriers and the protons are deposited into inter membrane space. Photosynthesis is the biological process that captures energy from sunlight and converts it into chemical energy.
Differences Between Cellular Respiration and Photosynthesis
As these organisms use sunlight to prepare their food, they are called photoautotrophs. Reaction takes places in presence of chlorophyll. The system separates hydrogen atoms into electron and protons 2. Photosynthesis does not occur without cellular respiration because the relationship between photosynthesis and cellular respiration is such that the products of one system are the reactants of the other. Carbon dioxide, water and light energy are the reactants of this process. Also, blue light is absorbed by carotenoids. The glucose made in photosynthesis is then used during cellular respiration.
Since these electrons have lost most of their energy they are excited again by photons of light that hit the chlorophyll 7. When you go through the concepts of cellular respiration and photosynthesis, you are bound to find some striking similarities. Light is first absorbed by photosystems that are made of chlorophyll and accessory pigments 2. Cellular respiration on the other hand, is the process occurring in the mitochondria by which organisms create energy to power cellular processes. Occurs in plants, protista algae , and some bacteria. At each transfer in the chain, the electrons release free energy that enables enzymes in the inner mitochondrial membrane to transport protons from the matrix to the intermembrane space 4.
Compare and Contrast Cellular Respiration to Photosynthesis Flashcards
Photosynthesis cannot exist with cellular respiration, they are completely linked together in providing the energy through the food we eat. Photosynthesis produces oxygen as a by-product, while aerobic respiration requires oxygen to even work. Photoautotrophs carry out both photosynthesis and respiration to survive; meanwhile, heterotrophs carry out only respiration for their survival. Think of these processes like baking. The energy of the sun is captured and stored in the bonds between atoms in glucose molecules.

Hence, the light reaction and the dark reactions are interdependent. The resultant compounds of these reactions are glucose and oxygen. Stages 4 stages: Glycolysis, Linking Reaction pyruvate oxidation , Krebs cycle, Electron Transport Chain oxidative phosphorylation. Cellular respiration is an example of an catabolic reaction as it is the breakdown of larger molecules to Mooresville smaller ones. The energy from the sun is stored in every molecule of glucose that is created.
Energy in Living Things Right now, even though you may just be sitting down and reading this lesson, your body is using energy. Upon arriving, we observed that the teacher, Ms. These processes are mutually related to each other. The series of redox reactions occur in cellular respiration in a particular order, starting with glycolysis, then moving to the Kreb's cycle or citric acid cycle, and ending with the electron transport chain. Once the cells have glucose, they use a series of chemical reactions to break down the glucose. Energy Changes in Photosynthesis The entire process of photosynthesis is the transfer of energy from the sun to the plant.

Pea plant cells rely on the process of cellular respiration to supply them with the energy that they need The Effect Of Light Intensity On Photosynthetic Rates organisms need to have a source of energy. Explain in your own words. It will experience tumor growth. Plants use photosynthesis to convert light energy from the sun to a more usable form during a process called energy transformation. The light reaction of photosynthesis occurs in the thylakoid membrane while the dark reaction occurs in the stroma of the chloroplast. Photosynthesis and cellular respiration are dependent on each other. In this process, carbon dioxide and water are taken as the reactants and made into the products of glucose sugar and oxygen.
