Cellular Respiration And Photosynthesis Essay

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).

In cellular respiration, glucose and oxygen are taken into the cells, then they are converted to carbon dioxide, water and ATP energy and some other energy. Some of the ATP energy is used in photosynthesis; a large amount of

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.

A. A number of organisms in the nonexistence of oxygen from time to time go through a course of action described as fermentation. Fermentation permits these organisms to create energy under anaerobic conditions according to (www.sci.uidaho.edu. 2008).

Like Photosynthesis, cellular respiration is also a redox reaction where glucose loses electrons and hydrogen atoms to produce carbon dioxide causing the glucose to become oxidized. At the same time, oxygen gains electrons and hydrogen atoms, reducing it to water.

The purpose of this lab is to determine the relationship between photosynthesis and cellular respiration.The effect of Light Intensity experiment will show the rate of photosynthesis based on the amount of light from the light bulb, temperature, and direction and distance of the light, these variables determine the absorbance. In the effect of Light Wavelength experiment, photosynthesis is affected by different light colors. Photosynthesis in this experiment is more successful with certain colors due to different pigments in chloroplasts only absorbs certain wavelengths. The rate of photosynthesis will be estimating oxygen production in spinach leaf using floating leaf disk procedure. The more floating disks, the more oxygen being produces

The purpose to cellular respiration and photosynthesis are to provide energy to both animal and plant cells. In photosynthesis, chloroplasts use carbon dioxide and light and produce glucose and oxygen, while in cellular respiration, the animal cell uses glucose and oxygen to produce carbon dioxide, water, and energy; which is the opposite of what chloroplasts do. The location of cellular respiration differ, the materials and products of each are opposites of one another, the different phases of that photosynthesis and cellular respiration have, and many other varieties of differences exist between plant and animal cells in cellular respiration and photosynthesis.

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.

Transitioning between photosynthesis and respiration: Photosynthesis transforms solar energy to stored chemical energy, and cellular respiration transforms that stored chemical energy to ATP which is an energy molecule that is then used by the cell. Light energy is used for photosynthesis in the chloroplasts ---> organic molecules + 02 ---> used---> Cellular respiration in mitochondria --- > produced ---> CO2 + H2O ---> photosynthesis (cycle starts over again).

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.

As mentioned before, cellular respiration and photosynthesis have complementary reactants and products. Evidently, carbon dioxide takes part in both processes, but contrast in roles. In the Krebs cycle of cellular respiration, six carbon dioxide molecules are made, but are simply given off as waste after the energy from glucose is evolved to ATP. On the contrary, carbon dioxide is a reactant in photosynthesis. The plants absorb carbon dioxide from the air, then fuse it with Rubisco in the calvin cycle to create

Cellular respiration is a sequence of three metabolic stages. Stage one is glycolysis and occurs in the cytoplasm. Stages two and three occur in the mitochondria and are respectively called the Krebs cycle and the electron transport chain. Both autotrophs and heterotrophs use these metabolic stages to produce the energy required to grow, reproduce and undertake maintenance, in the form of ATP (Flinders University , 2018). A step in the Krebs cycle can see an enzyme catalysed conversion of succinate to fumarate where an electron is transferred from one complex to another, a redox reaction (Knox, et al., n.d.). Substrate concentration is a variable used to increase the rate of a reaction. It is a limiting factor however, up until a certain point,

Photosynthesis and cellular respiration are two processes that go on in living things. Photosynthesis is a process used by plants and other autotrophs to capture light energy and use it to power chemical reactions that convert carbon dioxide and water into oxygen and energy rich carbohydrates. Cellular respiration is a process that releases energy by breaking down glucose and other food molecules in the presence of oxygen. This essay will compare and contrast these two functions

     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

     To metabolic pathways involved in photosynthesis are light reaction and dark reaction. The first stage of the photosynthetic system is the light-dependent reaction, which converts solar energy into chemical energy. Light absorbed by chlorophyll or other photosynthetic pigments is used to drive a transfer of electrons and hydrogen from water to and acceptor called NADP , reducing it to the form of NADPH by adding a pair of electrons and a single proton. The water or some other donor molecule is split in the process. The light reaction also generates ADP, a process called photophosphorylation. ATP is a versatile source of chemical energy used in most biological processes. The light reaction produces no carbohydrates such as sugars.
