All organisms use food molecules, like glucose to produce ATP. The production of ATP occurs during cellular respiration. ATP provides the cells with energy that is necessary to produce oxygen. The seeds/plants are autotrophic organisms, which produce their food from the energy that the light provides them. To release the stored energy within the food molecules, the germinated seeds carry out respiration and the release of carbon dioxide. Oxygen was being consumed and carbon dioxide was being released because the water level in test tube “G” continued to
The understanding of fermentation first came into light in 1789 by a french chemist known as Antoine Lavosier, who studied the transformation of substances. Through quantitive chemistry, he studied the mechanism of fermentation by estimating the general proportions of sugar and water molecules in sugarcanes with the with the end products such as carbon dioxide and ethanol; he also added yeast. In his conclusion, two thirds of the sugar was reduced into ethanol and the other one third was
photosynthesis and cellular respiration are extremely important in the cycle of energy to sustain life simply because nutrients would not metabolize in a productive manner. Both have numerous stages in which the process of energy occurs, and relationships with organelles located in the eukaryotic cell. Photosynthesis is a process by which green plant and other organism manufacture their food using sunlight to synthesize foods from carbon dioxide and water while cellular respiration is the oxidation of organic compounds that occurs within cells, producing energy for cellular processes. Photosynthesis occurs within organelles called chloroplasts. These organelles can absorb light, and are located inside of leaves. Within the leaf are tiny hole
Both photosynthesis and aerobic respiration are necessary processes in plants and provide energy. Aerobic respiration uses glucose (sugar) and oxygen to form carbon dioxide and energy while photosynthesis uses carbon dioxide and water to form glucose and oxygen. Photosynthesis may only occur during the day time while aerobic respiration occurs all the time. Since an increase in carbon dioxide levels indicates an increase in aerobic respiration and a decrease in photosynthesis, we can measure the net exchange of carbon dioxide levels and determine whether more photosynthesis or aerobic respiration at a particular time has occurred.
Purpose: The purpose of this experiment is to see how long it takes for the 10 spinach leaf discs to undergo photosynthesis and thereby rise in the two solutions.
For example, fermentation occurs in yeast in order to gain energy by transforming sugar into alcohol. Fermentation is also used by bacteria, they convert carbohydrates into lactic acid.
Although plants and animals have different methods of obtaining glucose, the cell respiration process occurs in both types of organisms. Many external factors in the environment may affect the organism's’ rate of respiration such as the temperature of the surrounding,
Elodea is a type of rooted plant with multiple branches (Elodea). Elodea is known as a weed located in parts of Australia, Africa, Asia and Europe, but is known to be popular in Washington’s lakes, ponds and rivers (Native Freshwater Plants, 1994). Photosynthesis involves light energy converting to sugar while respiration burns the sugars produced in photosynthesis in order to help the plant grow and reproduce (Whiting, 2014). The equation for photosynthesis is 6CO2+ 6H2O⇢C6H12O6+ 6O2. In other words, carbon dioxide, water and light are the reactants, and the products of photosynthesis are glucose and oxygen. Photosynthesis occurs in the chloroplast of plant cells. Respiration differs from photosynthesis because the reactants of respiration
Photosynthesis and cellular respiration are processes that help human beings live. The reactants in photosynthesis are carbon dioxide, water, and the sunlight’s energy. The products of these reactants are glucose and oxygen. Photosynthesis takes place in the chloroplasts in only plant cells. This is when plants convert carbon dioxide and water into glucose by using the sun’s energy. The two reactants in cellular respiration are glucose and oxygen. Cellular respiration has three products as a result of the reactants. They are carbon dioxide, water, and energy in the form of ATP. Cellular respiration takes place when living things convert glucose into cellular energy. The location of cellular respiration is in the cytoplasm and mitochondrion. The significance of cellular respiration and photosynthesis is they both help living things grow, develop, and stay alive.
permitted through facilitated diffusion involving glucose transporters. Glucose transporters are specialised for different cell types, for muscle and fat cells, type 4 glucose transporters (GLUT4) are used, as muscle cells are vital to athlete performance in the rainbow rage, GLUT4 shall be examined in this example. Firstly, insulin binds to insulin receptors on the surface of the cell. This sends a signal to GLUT4 vesicles from inside the cell initiating their movement to the cell wall. GLUT4 vesicles fuse to the outer cell membrane, catalysing the movement of glucose into the cell, this is the major endocytic process within cells. Glucose is then permitted entry into the cell by the process of facilitated diffusion, and can be used to produce ATP. Insulin
Cyanobacteria have photosystems 1& 2 whereas Chlorobi only have photosystem 1. Cyanobacteria are able to absorb light at both short and long wavelengths whereas Chlorobi can only absorb light at long wavelengths. In the reaction center of cyanobacteria, oxygen is produced whereas the reaction center of Chlorobi does not generate oxygen.
For similarities, both stories present cultures which celebrates the coming of age. They present the rite of passage intended to make the main character grow up. They matured and ready to face the world in a different perspective. Both stories also have a spiritual significance as the spirit moves also into a new age as well. The two stories also
Roles of each consist of the nucleus contain genetic material, which controls the actions of the cell, the cytoplasm is where the most chemical process happens and I controlled by enzymes. The Cell membrane controls the flow to and from the cell, the Mitochondria has the most energy released by respiration. In the Ribosomes protein synthesis occurs, and in the extra parts of the plant structure is functions like the cell wall, which strengthens it. The Chloroplasts contains chlorophyll, it absorbs the light for photosynthesis, and finally the permanent vacuole is filled with cell sap that helps keep the cell
The term fermentation refers to the chemical breakdown of a substance by bacteria, yeasts, or other microorganisms, typically involving effervescence and the giving off of heat (wikipedia). Sugars are converted to ethyl alcohol when fermentation happens. In this experiment we determined if yeast cells undergo fermentation when placed in a closed flask with no oxygen. Glucose and yeast are mixed together in a closed flask and allowed to incubate for about one hour. Then, tests are performed to determine if the products of aerobic and anaerobic respiration are present in the flasks.The citric acid cycle consists of a series of chemical reactions used by all aerobic organisms to release stored energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins into carbon dioxide and chemical energy in the form of ATP (Biology). The tests detect the presence of carbon dioxide and ethanol. Carbon dioxide should be present irrespective of the type of respiration taking place, but ethanol is present only if fermentation has occurred. Another factor that can indicate whether fermentation occurred or cellular respiration occurred is the amount of glucose utilized during incubation.Fermentation uses more glucose because the process of fermentation is much less efficient than cellular respiration in terms of energy production per molecule of glucose used. The open flask (control) and the closed
Throughout the semester in AP Biology I’ve been able to cover several different topics. These include being able to identify biological processes that require energy, investigating and modeling ways organisms capture and store free energy for use in biological processes and investigating and explaining how organisms respond to changes in their environment. Over the semester I have been able to gain a full understanding and can demonstrate proficiency in each of these components of the curriculum. The work that I have completed involving these topics shows this.
