Cellular Respiration

             The role of plants in their natural environment is to absorb excess carbon dioxide and produce oxygen to replace the CO2 in the air. Carbon dioxide is harmful because it is toxic and because it is one of the gases that causes the greenhouse effect. Oxygen is essential to life and it also forms ozone (O3), which protects earth's inhabitants from ultraviolet rays.
             2. Photosynthesis involves a series of chemical reactions, where the product of the first reaction is used as a reactant in the second, and so on. This is called a biochemical pathway. This pathway can be broken down into three steps.
             1) CO2 diffuses into the stroma from the cytosol. An enzyme then reacts with the CO2 and combines it with a molecule known as RuBP. Product immediately splits into 2 molecules called PGA.
             2) The PGA is then converted into PGAL by receiving a phosphate group from an ATP molecule and a proton from NADPH.
             3) Most of the PGAL is converted back into RuBP, releasing energy. But some is sent to other parts of the plant cell to make other organic compounds.
             3. Photosynthesis and cellular respiration both involve the absorption of gases and the release of a by-product, but photosynthesis involves the absorption of carbon dioxide and water and the release of organic compounds and oxygen, while respiration is exactly the opposite. The amount of CO2 in the are will also affect photosynthesis, since CO2 is imperative to photosynthesis.
             4. Factors affecting photosynthesis would be light intensity and temperature. As light intensity increases, the rate of photosynthesis increases rapidly and then levels off at a maximum. As temperature increases, the rate of photosynthesis increases, levels off, and then declines at the same rate.
             5. Adaptations that maximize conditions for photosynthesis would be the plants that arrange their leaves in different ways so that most of them are available to the sunlight. Another would be that all plants grow towards the sun.


Essays Related to Cellular Respiration

1. Cellular respiration

... investigate the effect that changing the amount of substrate (succinate) will have on the cellular respiration rate. We hypothesized that as the substrate (succinate) increases the rate of cellular respiration will increase. And our prediction was that if increased substrate increases the rate of cellular respiration, then respiration will be greater in the solution with more Succinate and this tube should turn from ... the figure 1.2, we clearly see that tube 3 had higher respiration rate due to the increasing transmittance. Which supports the hypothesis because tube 3 contained more ...

3. Photosynthesis and Cellular Respiration

... chemical energy. In photosynthesis, water, carbon dioxide, and sunlight is used to form glucose and oxygen. Photosynthesis can be carried to other organisms when the molecules are ingested as food. Cellular respiration is a catabolic pathway where organic molecules are broken down to release energy. In this reaction, organic molecules are broken down by oxygen which results in carbon dioxide and water ... . Cellular respiration is the opposite of photosynthesis. They form a cycle of where the products of one metabolic pathway forms the reactants of the other metabolic pathway. The forest...

... it results in a process that is the opposite of photosynthesis in the sense that photosynthesis removes CO2 from the atmosphere and this process puts it back. This process is called cellular respiration. Cellular respiration is a process performed by all organisms where a chemical reaction occurs, in which energy from glucose is produced in the form of ATP (Adenosine Triphosphate). C6H12O6 + O2  CO2 + H2O + Energy ...

7. Plants

... other living things obtain and use oxygen. Except for certain micro-organisms, all living things require oxygen to live. Respiration also involves the elimination of carbon dioxide, a gas produced when cells use oxygen. Respiration may be divided into three phases: (1) external respiration, (2) internal respiration, and (3) cellular respiration. In external respiration, or breathing, a plant or animal takes in oxygen from its environment and releases carbon dioxide. In internal ... respiration, oxygen is carried to the cells of the organism and carbon dioxide is carried away from them. ...
