Respiration Vs Photosynthesis

Cellular Respiration is the physiological process of converting molecules into ATP. This process can occur in bacteria, protists, fungi, plants, and animals. It uses Oxygen (02) and Glucose (C6H1206) to transfer and transform electrons. Then it produces carbon dioxide (CO2) and Water (H2O). Thus, it is read as C6H12O6 + 6O2 --> 6H2O + 6CO2 + 32ATP. Respiration is split into three steps Glycolysis, Citric Acid Cycle, and Electron Transfer Chain (ETC).

Both photosynthesis and cellular respiration are the main pathways of energy transportation in organisms. However, the reactants and the products are exact opposites in photosynthesis and in cellular respiration.

The last step of cellular respiration is the Electron transport chain (ETC). The ETC takes place in the inner mitochondrial membrane. Electrons from Hydrogen are carried by NADH and passed down an electron transport chain to result in the production of ATP. Results are the production of ~32 ATPs for every glucose. Oxygen, which is the final electron receptor, finishes the process by creating a water molecule and combining the remaining hydrogen molecules. Oxygen is the final electron receptor. Without it, the process cannot be complete (Cellular Respiration, 2004). The waste products of cellular respiration are CO2 and H2O that are the same incrediants used in photosynthesis. Plants store chemical energy by photosynthese and then harvest this energy via cellular respiration.

Cellular respiration is a redox reaction that combines glucose & oxygen to produce carbon dioxide, water, and energy.

In photosynthesis H+ ions are vital in the production of the energy source that is ATP, which is used in several metabolic processes, such as respiration. The photolysis of water produces H+ ions, electrons and O2. The excited electrons lose energy as they move along the electron transport chain, this energy is used to transport the H+ ions (protons) in to the thylakoid, which causes a higher concentration of H+ than there is in the stroma, thus causing a proton gradient across the membrane. The H+ then proceed to move down the concentration gradient into the stroma via the enzyme ATP synthase. The energy from this process is called chemiosmosis and combines ADP with inorganic phosphate (Pi) to form ATP. Light energy is then absorbed by photosystem I (PS I) which excites the electrons to a higher energy level. These electrons are transferred to NADP with H+ ions from the stroma to form reduced NADP. The whole of this process is

Unlike photosynthesis, cellular respiration is an exergonic reaction where energy is released, rather than absorbed. This released energy is called ATP, the energy currency of the cell.

Every living thing needs cellular respiration to survive. Cellular respiration is the process that releases energy by breaking down glucose and other food molecules in the presence of oxygen. This process happens through three distinct operations which are glycolysis, the Krebs cycle, and the electron transport chain. Throughout these cycles, our bodies turn oxygen and glucose into carbon dioxide, water, and energy. Although this system seems simple enough, cellular respiration can not take place in just one step because all of the energy from glucose would be released at once, most of it being lost in the form of light and heat. All this plays a very important role in our lives and without it, organisms would cease to exist.

Cellular respiration is a process that happens in all living eukaryotic cells. What cellular respiration does is turn food often carbohydrates into energy for our bodies. Cellular respiration starts with a carbohydrates sugar called glucose. What it does is alter and break down the six carbon molecule glucose and altering it creating two three carbon molecules called pyruvic acids in an anaerobic process called glycolosis (Cellular respiration). What this process does is create two ATP molecules which are basically molecules which provide energy to run all cellular processes in our bodies (king). However, from here in the process can turn aerobic, meaning using oxygen if present or anaerobic meaning when oxygen is not present in a

Cellular respiration and photosynthesis share many similarities in structural components and processes, such as the fact that both derive energy from electrons as they pass through a chain. With the use of electron transport chains, both processes move hydrogen ions across a membrane to form a chemiosmotic gradient. Both systems use this gradient to move hydrogen ions through the membrane passively and into an ATP synthase molecule, which yields ATP molecules. We see the intermediate molecule G3P in cell respiration and photosynthesis, which goes on to form glucose or other complex compounds. Both systems share unique and similar characteristics that make life possible for both plant and animal cells.

Photosynthesis equation and the cellular respiration equation are both really important for every living organism. They both help living organisms stay alive. Photosynthesis takes place inside the plants chloroplast. Inside the chloroplast the energy is being stored waiting to be released to help fuel the plant, which then releases oxygen outside the plant. The first step of the process is capturing the sun’s energy.

    Cellular respiration is the group metabolic reactions that happen in the cell of living organism that creates adenosine triphosphate, ATP, from biochemical energy. The formula for cellular respiration is C6H12O6 +6O26CO2+6H2O+ATP.  This formula means glucose and oxygen are turned into water,carbon dioxide and adenosine triphosphate (ATP) energy through chemical reactions. Cellular respiration occurs in all cells which allows them to grow. Raphanus raphanistrum subsp. Sativus seed, also known as radish seed, undergo cellular respiration because they are not yet able to perform photosynthesis, which is how plants create their energy. Hymenoptera formicidae,commonly known as ants, undergo cellular respiration to produce the energy they need to live.

Photosynthesis and cell respiration are different in multiple ways. Photosynthesis occurs in the chloroplasts while cell respiration occurs in the mitochondria. Photosynthesis is the process in which plants create glucose and oxygen needed for cell respiration. Cell respiration is the process in which plants and animals create ATP. Adenosine triphosphate provides energy for the cell.

The best example of photosynthesis is anabolism, because of the energy and raw materials it uses produce larger glucose molecules. Catabolism is an excellent example of cell respiration because it breaks a molecule of glucose and releases the stored energy. Catabolism uses its cell energy to fuel anabolic reactions to its cell components. Simultaneously the anabolism and catabolism occur in the cell, but they are both controlled independently (Schlager, 2002). There use different pathways because the catabolism pathway is a downhill process because they break down those complex molecules to slow down energy. While the anabolism’s pathway energy is released and it becomes an uphill process because it builds up, complex molecules used to store

1) During Photosynthesis plants use sunlight to make energy and later use that energy to make glucose by taking in CO2. So it takes in Carbon from the atmosphere and stores it as sugar. Cellular Respiration is using that sugar to make ATP. In this process CO2 is released. These two processes contribute to the Carbon cycle because one takes in the CO2 and the other releases CO2. They are like the converters of the cycle.

     Photosynthesis has a two-stage performance before plants produce the two products they are known to produce. These stages are Photosystem I and II. Photosystem II is dependant on light reactions for energy which causes the electrons to be react and be transferred to Photosystem II. The electrons are transported through the Photosystem II electron transport system, however some energy is used to drive ATP synthesis. Meanwhile, light is being absorbed by the Photosystem I, which causes the electrons to react. This process sends the electrons to the Photosystem I transport system where some energy is released as electrons travel through the electron transport system and is captured as NADPH. When this process is completed oxygen is released from the plant and glucose has been
