Photosynthesis and Cellular Respiration

Photosynthesis and aerobic respiration are both part of a cyclic process of biochemical reactions. Photosynthesis requires the products of aerobic respiration (carbon dioxide and water), while aerobic respiration requires the products of photosynthesis (glucose and oxygen). Together, these reactions are involved in how cells make and store energy. The energy transfers in both processes and in how the gas exchange between oxygen and carbon dioxide occurs and the end products that result from each process are somewhat opposite processes, thus aerobic respiration and photosynthesis are in some ways complete opposites of each other. Photosynthetic organisms such as plants use solar energy to reduce carbon dioxide into carbohydrates. During respiration glucose is oxidised back to carbon dioxide, in the process, releasing energy that is captured in the bonds of ATP. Although these two energy producing processes differ in their uses and also their goals, they do have several similarities.
Photosynthesis is a chemical process that takes place in the presence of sunlight, wherein plants manufacture their food and build stores of energy. This phenomenon occurs in chlorophyll containing plant cells. Chlorophyll is a pigment found in plant leaves that gives the plant its green colour. Chlorophyll absorbs the light energy and utilises it to produce carbohydrates from carbon dioxide and water. These carbohydrates produced are used by the plants as a source of immediate energy for growth, reproduction, and absorption of nutrients. The chemical reaction produces oxygen which is released into the atmosphere.
Photosynthesis can be summed up by the following equation
6CO2 6H20 Sunlight ïƒ C6H1206 6O2, (fig1 below illustrates the process of photosynthesis)
Occurring in the chloroplast light reaction converts solar energy to chemical energy of ATP and NADPH.The light reactions use the solar power of photons absorbed by Photosystem I and II. These are light gathering antennas containing the chlorophyll primarily responsible for absorbing the light. Electrons are also carried from Photosystem I and II via NADPH to the Calvin cycle. The Calvin cycle uses ATP

Behaviour of Termites: Breeding and Effects of Repellents

Introduction and Review of Literature General biology of termite
Termites are social insects that live in colonies, which, in turn, function because the complementary roles played by the different caste. In United States, subterranean termites, Coptotermes spp. and Reticulitermes spp. are the most destructive and cause substantial economic damage to buildings/structures (Su
