Oxygen in Liquids (DISSOLVED OXYGEN) Dissolved Oxygen – the amount of dissolved oxygen in a body of water as an indication of the degree of the health of water and its ability to support a balanced aquatic ecosystem. Oxygen – is a clear‚ colorless‚ odorless‚ and tasteless gas that dissolves in water. Small but important amounts of it are dissolved in water. OXYGEN: Aquatic Life Depends on it Plants and Animals depend on dissolved oxygen for survival. Lack of dissolved oxygen can cause aquatic

Radiation on the Respiration Rate of Phaseolus vulgaris Aerobic Celluar Respiration is a process that is carried out by most living organisms. The process is a series of chemical reactions that occur within the mitochondrial matrix and cristae of eukaryotic cells. Following the anaerobic process of glycolysis‚ partially broken down sugar molecules enter the matrix of the mitochondria where they are further reduced by oxygen. In the process‚ a small amount of ATP is created and a large amount of electrons

Introduction Respiration is the number of processes which leads to the oxidation of organic compounds to produce the energy. There are several types of respiration‚ and one of them is aerobic. During the aerobic respiration‚ human uses the oxygen from atmosphere and produce carbon dioxide. A cardiorespiratory system which includes lungs‚ heart‚ blood vessels and others is responsible for all the processes linked to the respiration and controlled by the nervous system. During rest and maximum

Mashrek International School Investigate the Factors that Affect the Rate of Respiration in Yeast. (Temperature) Fawzi El Ansari Biology HL Title: Investigate the Factors that Affect the Rate of Respiration in Yeast. (Temperature) Aim: The aim of this experiment is to investigate the effect of changing the temperature on the rate of respiration in yeast. This will be done by placing equal amounts of yeast in each beaker that contains the same pH solution. Each beaker will be mixed with glucose

These are the cells that transport oxygen in the blood from the lungs to the tissues. These cells also help transport some of the carbon dioxide from the tissues to the lungs. The main function of erythrocytes‚ namely oxygen transport‚ is carried out by the protein that makes up the majority of the protein composition of the cell‚ hemoglobin. We will also be looking at how hemoglobin delivers oxygen‚ and how many factors affect its affinity for oxygen. Lastly we will be looking at some

Oxygen Cycle Required for Life All living things use oxygen or depend on organisms that use oxygen in some way. All Animals and Other Consumers Use Oxygen We use oxygen to break down simple sugar and release energy. This can be done through respiration or fermentation. Animals mainly use respiration.

oD 4.1 Respiration Why organisms undergo respiration What is respiration and why do we need it? Respiration is the process whereby energy is released from food molecules (most usually glucose). It takes place inside living cells‚ both eukaryotic and prokaryotic. The process takes place inside the cytoplasm and the mitochondria. Energy is used to synthesise adenosine triphosphate (ATP)‚ which acts as a short-term energy store in cells. All living organisms need energy to drive their

is the temperature at which water changes phase from a liquid to a solid or vice versa. The freezing point describes the liquid to solid transition while the melting point is the temperature at which water goes from a solid (ice) to liquid water. In theory‚ the two temperatures would be the same‚ but liquids can be super cooled beyond their freezing points so that they don’t solidify until well below freezing point. Ordinarily the freezing point of water is 0° C or 32° F. The temperature may be lower

Macronutrients are nutrients that come in large amounts. They include water‚ carbohydrates‚ proteins‚ and fats. What are micronutrients? • Micronutrients are nutrients that come in small amounts. They include minerals and vitamins. How are minerals defined? What functions do they play? • Minerals are essential for the function of our cells. They are inorganic because they don’t contain any carbon. Minerals help your muscles‚ bones‚ blood‚ absorption of oxygen‚ and your brain function. What role do enzymes
