The concentration of 1-kestose isomer increased steadily with time from 0 - 80 min. During this time‚ sucrose was significantly influencing the rate of 1-kestose formation and hence the optimum concentration of the 1-kestose isomer was observed at 80 min. After 80 min‚ the 1-kestose concentration gradually decreased. This was because the invertase active sites had become saturated with sucrose (substrate) or sucrose had been used up in the reaction. Therefore‚ there was a gradual decrease observed

Title: Showing Cellular Respiration through Alcoholic Fermentation Abstract: The experiment was conducted to determine the impact different yeast amounts had on yeast fermentation. It was hypothesized that the more yeast added the more CO2 would be produced. The carbon dioxide production was measured in the fermentation of yeast with solution of no yeast in test tube 1‚ 1mL yeast in test tube 2‚ and 3mL of yeast in test tube 3 over a period of twenty minutes. All of the yeast amounts produced

energy production. They are also the responsible location for which respiration takes place. Mitochondria contain enzymes that help convert food material into adenosine triphosphate (ATP)‚ which can be used directly by the cell as an energy source. Mitochondria tend to be concentrated near cellular structures that require large inputs of energy‚ such as the flagellum. The role of the mitochondria is very important in respiration. In the presence of oxygen‚ pyruvate or fatty acids‚ can be further

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 and cellular respiration

questions: 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

“Investigate the factors affecting the rate of yeast respiration” Lab Report Introduction The aim of this experiment was to investigate the effect of different amounts of a substrate on the respiration rate of yeast and to compare this to the effect of different amounts of glucose on the rate of yeast respiration. The substrate which I chose to further investigate was fructose. Fructose is a fruit sugar which is one of the three‚ along with glucose and galactose‚ dietary monosaccharides that

Title : Comparing the rates of pulmonary and cutaneous respiration in frogs Introduction Frogs are amphibians that live in moist environments to support one of their key mechanisms of respiration. Frogs have the ability to breathe many diverse ways‚ due to their unusual life cycle and aquatic and terrestrial environment. The Order Anura shows the extreme anatomical and physiological diversity. Many frogs use lungs to respire‚ bringing in air through their nares‚ mouth‚ into the trachea and then to

Photosynthesis and cellular respiration are key ecological concepts involved with energy flow. Use Figure 9.2 to label the missing parts below. See page 163 of your text for labeled figure. Concept 9.1 Catabolic pathways yield energy by oxidizing organic

Aerobic cellular respiration and oxygenic photosynthesis are two cellular processes that have evolved in similar ways. Cellular respiration is responsible for the process of ATP‚ meanwhile oxygenic photosynthesis is the process of turning light energy into food. It is evident that both of these processes have their own reactants‚ products‚ and biochemical pathways. Both of these processes have evolved from their primitive original state‚ but it is important to understand that oxygenic photosynthesis
