essay on photosynthesis and cellular respiration

Sunlight in the form of light energy is used to fuel the photophosphorylation process where 2 water molecules break down into 4 H+ ions, 1 oxygen molecule, and 4 electrons. In contrast, The site of photosynthesis is chloroplast, while the sites of cellular respiration are cytoplasm and mitochondrion. There are specific types of transport proteins that allow specific materials to cross. They are also different in the fact that photosynthesis creates glucose and releases oxygen into the atmosphere while cellular respiration creates energy and releases carbon dioxide and water into the atmosphere. By this meaning that each separate reaction, the chloroplast requires 6 water molecules and 6 carbon molecules, and additionally little sunlight energy. There are some similarities between the process involved however their products and reactants are the exact opposite. Chlorophylls are indisputably the dominant pigment masking the reflective wavelength properties of yellow, orange, and red pigments.

essay on photosynthesis and cellular respiration

The flow of electrons through photosystems and other molecular components into the thylakoid membrane is called linear electron flow. In Cellular respiration oxygen is used up to make carbon dioxide, oxygen undergoes several steps to be converted into carbon dioxide, which will later be used by photosynthesis. About the same time, the biochemist Robert Hill found that exposure to light of green cells in a test tube in the presence of hydrogen acceptors resulted in the liberation of oxygen, but no carbohydrate was synthesized. The three stages are: glycolysis, citric acid cycle, and. Both photosynthesis and cellular respiration are the main pathways of energy transportation in organisms. The other process is aerobic respiration.

One major difference between the two is that photosynthesis takes place completely in plants while respiration occurs equally in plants and animals. We will determine whether or not it is possible to examine the relationship between photosynthesis and cellular respiration under controlled environmental conditions. In the end, we see that both phtosynthesis and cellular repiration are necessary for living organisms. The word photosynthesis means putting together with light. Each pyruvic acid 2 converted to Acetyl CoA 2 2.

Respiration and Photosynthesis

essay on photosynthesis and cellular respiration

In chloroplasts, light reaction occurs in the thylakoids occupied by two photosystems that move electrons across the thylakoid membrane. Each of these differently-colored pigments can attract a slightly different color of light and pass its energy to the central chlorophyll molecule to do photosynthesis. We will also measure the production of 02 the experiment in the experiment. Plants, for example, which are eurokayto are such organisms that live by photosynthesis. Cellular respiration can utilize other molecules beside glucose, but it always results in energy, water and carbon dioxide. Adenosine triphosphate is made of the organic molecule adenosine bonded to a chain of three phosphate groups.

Organic and inorganic are common types of this and it only differs from one another by substance in raw materials use. Anther type of protein is the carrier protein. Cellular respiration occurs in the mitochondrion of the cell and photosynthesis occurs in the chloroplast. Contrast and compare an absorption spectra versus an action spectra for Ps. Discuss why is the narrow area of electromagnetic radiation. Part D — Chloroplast structure and function In eukaryotes, all the reactions of photosynthesis occur in various membranes and compartments of the chloroplast.

This is now called the Hill reaction. Fig: 2 : Shows a cycle and how photosynthesis and respiration are dependent on each other. Chlorophyll is… Words 446 - Pages 2. They form a cycle of where the products of one metabolic pathway forms the reactants of the other metabolic pathway. However, the reactants and the products are exact opposites in photosynthesis and in cellular respiration. There are two steps in aerobic respiration: Krebs cycle and the electron transport chain. Without the phosphates the process finishes with two 3-carbon piruvates.

There are other differences too, however. Photosynthesis is not a single process…. We encountered that as the amount of light intensity increases the rate of cyclosis decreased as well, and therefore having an effect on the leaves ability for photosynthesis Formulate alternative hypothesis. Photosynthesis takes in carbon dioxide from the animals and cellular respiration takes in the oxygen from the plants. Site of Reactions Photosynthesis takes place in the chloroplasts and organelles of a plant cell. They are at different energy levels, and under the influence of light the energy state of an electron can be raised, enabling it to be transferred from one system to the other. As all cells need energy through the sugar they made in their leaves; oxygen moves through diffusion through the plant from cell to cell.

Part C — Redox reactions of photosynthesis In photosynthesis, a redox compound that is produced in the light reactions is required to drive other redox reactions in the Calvin cycle, as shown in this figure along with other components of photosynthesis. All life depends on these reactions because we need oxygen, and this oxygen comes from the plants that releases it from photosynthesis. By May this not only became Georgia's biggest recorded fire but also Florida's with 130,466 acres of land. As electrons pass through the cytochrome complex, H+ diffuse in the thylakoid space from the stroma, contributing to the proton gradient used for chemiosmosis. Table 1: Rate of Photosynthesis Measured by the Number of Oxygen Bubbles Light Bulb Trial 1 Trial 2 Trial 3 Average O watts 2 3 25 watts 7 4 5 50 watts 11 100 watts 12 13 Conclusion In conclusion, the outcome of this experiment was what I expected it to be. Oxygen can then be added back to the lactic acid to form piruvate again.

In all cells except the photo synthetic cells discussed above, and the chemosynthetic bacterial cells mentioned previously, the raw materials employed in synthetic reactions comes from the digestion of prefabricated materials taken into the organism. Photosynthesis is a process used by plants and other organisms to convert light energy, normally from the Sun, into chemical energy that can be later released to fuel the organisms' activities. Cellular respiration ultimately makes carbon dioxide, which is accepted by plants and undergoes photosynthesis. Cellular respiration is what the plants need and photosynthesis is what the organisms or the animals need. Despite, respiration uses glucose and oxygen to produce carbondioxide and water as waste products. Explain how photosynthesis and respiration are linked in order to provide you with energy from the food you eat.
