Diffusion & Cell Size Lab Background The absorption of nutrients‚ excretion of cellular wastes‚ and the exchange of respiratory gasses are life processes which depend upon the efficient transport of substances into‚ out of‚ and throughout living cells. The process of diffusion can be easily visualized by adding a drop of blue food coloring to a glass of water. Initially‚ the food coloring remains in a small area in the water‚ dying it a dark blue. Over time‚ the molecules of food coloring

series of biochemical reactions in which one glucose molecule is oxidized into two pyruvic acid molecules and a small amount of adenosine triphosphate (ATP). Generation of high energy molecules are used as cellular energy sources in aerobic and anaerobic respiration. The products formed through glycolysis usually enter into the citric acid cycle and the electron transport chain to produce more energy. Fructose enters the glycolytic pathway through the liver or skeletal muscle. For example‚ in the liver

Analysis: In this lab we measured the rate of respiration of germinating mung beans and germinating peas at room temperature and 10 degrees Celsius. The rates of respiration at room temperature were higher than the rates of respiration in cold water. The reaction rate of the germinating peas at room temperature was .0125 ml/min and the reaction rate of the peas at 10 degrees Celsius was .0095 ml/min. The same is true for the germinating mung beans. At room temperature the rate of reaction was .0105

process such as photosynthesis and cellular respiration. Photosynthesis uses the carbon dioxide that is in the atmosphere to transform it into sugar and oxygen; cellular respiration puts carbon dioxide in the air. Both of these processes were studied during the experiment. In the experiment‚ the tube with both the elodea and the snail had the same level of carbon dioxide in both the light and dark tube. This occurred because the snail performed cellular respiration‚ and the elodea performed both photosynthesis

Cellular respiration: • What is cellular respiration and what are its three stages? Cellular respiration is the set of the metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP)‚ and then release waste products. The reactions involved in respiration are catabolic reactions that involve the redox reaction (oxidation of one molecule and the reduction of another. Respiration is one of the

Photosynthesis and Cellular Respiration lab makeup Photosynthesis absorbs energy from the the sunlight ‚and water‚and carbon dioxide to to create energy sugar ‚and oxygen. Photosynthesis also absorbs molecules that are called pigments. The process of photosynthesis is used by plants to make food for themselves. By then doing this‚ it also benefits us humans and animals by releasing carbon dioxide. Oxygen to them is considered a waste product‚ but a necessity to us. The photosynthesis
