as the graphical representation of the rate of photosynthesis against wavelengths of light. The graph shows how effective the different wavelengths of light are at enabling photosynthesis‚ and this can be determined by measuring either the carbon dioxide consumed or by the amount of oxygen released. Chlorophyll is a pigment found in the chloroplasts of organisms. In plants‚ it is the chlorophyll that absorbs the light energy and drives photosynthesis. On the absorption spectrum‚ chlorophyll a and

Title: The success of photosynthesis in geranium leaves using visible light wavelengths obstructed by black paper‚ and red‚ blue‚ and green translucent filters. I. Abstract Photosynthesis is a process in which plants use light‚ water‚ and carbon dioxide to produce sugars‚ water and oxygen. Chlorophyll a and chlorophyll b‚ in the chloroplasts of a leaf‚ are responsible for absorbing wavelengths of light for use in photosynthesis with red and blue wavelengths being optimal. Testing

Respiration is a process which releases energy from energy-rich molecules such as glucose. The glucose is converted into energy which is usable for life processes. Burning‚ or combustion‚ is a reaction between a substance and a gas to release energy. These two reactions have many similarities but are not the same. This essay will identify some of similarities and differences between the two processes. The first similarity is that both respiration and burning use oxidation to release energy. In respiration

M1- Discuss the role of energy in the body‚ describe the process of cell respiration and give three examples of how energy is used in the human body Every living cell needs energy. The form of energy that we use is chemical energy in the form of glucose that we get in our food‚ mainly from carbohydrates such as bread‚ pasta and potatoes. Living cells cannot function without energy‚ which can then lead to death. To release the energy from glucose‚ oxygen is added (oxidise glucose) by breathing continuously

are a lot more red blood cells in the circulatory system. The effect of blood doping is that due to the increased number of red blood cells‚ more oxygen can be carried by haemoglobin to the working muscles. The benefits of bloody doping are that aerobic capacity is increased and fatigue is delayed making the endurance athlete able to sustain a high level of performance throughout their event/race. The risks of blood doping are that: blood viscosity is increased leading to a lower heart rate and clotting

Aerobic Respiration Do you know indulging in physical movements is associated with a chemical reaction? The process requires energy‚ which is yielded by aerobic respiration. Over here‚ respiration helps breaks down glucose (an energy source) into water‚ carbon dioxide and energy in form of ATP (adenosine triphosphate). The balanced cellular respiration equation is represented as: C6H12O6 + 6O2 → 6CO2+ 6H2O + Energy (36 ATPs) Anaerobic Respiration Due

than 38 ATP molecules for every glucose molecule that is oxidized by aerobic respiration is because the NADH that is made in the cytosol during glycolysis cannot diffuse through the inner membrane of the mitochondrion‚ it must be transported into the mitochondrial matrix. So as a result the active transport of NADH consumes ATP releasing only 36 ATP molecules. 18) Anaerobic pathway differs from the pathways of aerobic respiration at the sites they occur in eukaryotic cells by the presence of oxygen

Through photosynthesis the suns energy is constantly being transformed into glucose‚ which is a chemical energy. Respiration is the chemical activity that occurs in all plants and animal cells that release the energy from the glucose. Photosynthesis cannot exist with cellular respiration‚ they are completely linked together in providing the energy through
