Aerobic respiration is the release of energy from glucose or another organic substrate in the presence of Oxygen. Strictly speaking aerobic means in air‚ but it is the Oxygen in the air which is necessary for aerobic respiration. Anaerobic respiration is in the absence of air. Here is a molecular model of a glucose molecule. You do not need to memorise the diagram for you GCSE exam‚ but it should help you to understand that a molecule of glucose contains six atoms of Carbon (shown in blue)‚ twelve

Academic Convention Essay When analyzing readings and writings of academic discourse‚ readings and writings found outside the college setting‚ there are common patterns and disciplines that are evident in these writings. In her essay titled “Teaching the Conventions of Academic Discourse” English professor Teresa Thonney argues that “there are shared features that unite academic writing and that by introducing these features to first year students we provide them with knowledge they can apply and

Yeast Population Dynamics Lab How Environmental Factors Affect a Yeast Population’s Ability to Reproduce OBJECTIVE The objective of this experiment is to emphasize the influence that limiting factors have on a population. This lab tests yeast‚ a common component in baking‚ against two environmental factors (changes in temperature or concentration) to see what effect these have on the population dynamics of the yeast over a period of 72 hours. There are two sections of tests included in this

Goldfish Respiration Abstract The purpose of this experiment is to design and conduct a basic scientific experiment‚ identify and control variables. Some other objectives that we learned is to write a formal hypothesis‚ identify the basic and integrated process skills of science that were used in this experiment. Also‚ we will learned the effects of temperature on goldfish respiration. This experiment will be conducted with four students ‚ one goldfish‚ thermometer‚ a stop watch‚ and a beaker

INTRODUCTION Cellular respiration is a biochemical pathway in which cells produce ATP or energy and carbon dioxide as metabolic waste by breaking down the chemical bonds of food molecules. Cellular respiration is a type of aerobic respiration which needed oxygen in order to produce ATP which occurring in the mitochondria. Meanwhile‚ in the absence of oxygen‚ the cells will undergo anaerobic respiration to produce ATP in the cytoplasm. Anaerobic respiration can be divided into two parts which are

Discussion The purpose of this experiment was to determine if splitting a bean would affect its rate of respiration. Splitting a bean does not impact its rate of respiration. This is shown in the data‚ while the average rate of respiration for Whole beans is 1.35 and the rate of respiration for 1.16‚ the standard error of the mean is .15. Because the standard error of the mean is so high‚ they overlap in both of the data sets‚ which shows that the data is very similar. This is better shown in the

proportional to the intense of the respiration process that was taking place (Doltar et al.‚ 249). This means that there was high rate of respiration at a temperature of 30°C test tube as compared with the other three test tubes. The optimum temperature for enzyme activity is usually between 35-37°C (Burchfield‚ 303). At this temperature the enzyme activity is maximum and thus the rate of respiration is very high at this temperature. This is the reason why the rate of respiration was very high at the range

An observation was made on whether or not the sugars‚ fructose and ribose would be fermented in yeast (Saccharomyces cerevisiae). By looking at the chemical structures of these sugars given in (Figure 1)‚ we looked for anything that might determine the metabolization of these sugars. An equal 6mL (milliliter) sample of 2.5% fructose and yeast suspension was pipetted into a fermentation tube. The same procedure above was performed with the sugar ribose which has a concentration of 2.5% as well
