Metabolic Rate In Manduca Sexta

Better Essays
Metabolism is a complex process in organisms that convert the food into energy for organism to function properly. Metabolic rate is typically defined as the amount of energy the organism is currently using to maintain the activity (Perkin, 2015). Since metabolism is a key in sustaining the organisms’ life, we decided to investigate the experiment about metabolic rate caterpillar, Manduca sexta. There are many techniques used to measuring the metabolic rate, but there are only best method that can be done in laboratory: “quantification of heat production and quantification of gas consumption” (Perkin, 2015).Our investigation is about measuring the oxygen consumption of the caterpillar in the trial duration when it was placed in sealed chamber along with chemical absorbing CO2 produced. Metabolism are mostly varies in each different organisms, therefore, a question for our investigation to what factor affect the metabolic rate in animal, especially in Manduca sexta. Our hypothesis that there are numerous possible factors including temperature, gender, age, body composition and body mass can affect the metabolic rate of an organism. As we expected, a study from the past

However, from the graph (Fig. 1), there is no trend as to the volume of O2 consumption in 15min (mL/min) in larger organism are more than smaller ones. Based on the Regression analysis, we found no statically significant correlation between the body mouse and its metabolic rate because P value is 0.079 (>0.05). Therefore, our data does not support our hypothesis that was the body mass of Manduca sexta affects its metabolic rate the most because animals with higher mass need to burn more energy to support the extra weight and help the body keep

    researched in infants, they found that infants born with gastroenterology diseases or disorders were unable to harvest energy from food they consumed and therefore suffered severe growth stunts and defects. The relationship between food and calories can now be established because food provides the calories the body needs to carry out living processing through the process of metabolism. There are many metabolic pathways in each cell that different types of foods go through. However, all of these pathways oxidize the food source and yield…

    OBJECTIVES - To understand protein intake better. - To understand how consuming too much or too little of certain food specifically protein can be unhealthy and do harm to our body over time. - To determine what foods are providing the right type of proteins INTRODUCTION The human body has thousands of different proteins all of which are necessary for staying alive and healthy. Protein is a very important substance that is needed by humans for protein is not just a structural material, such as fats and carbohydrates. Protein is a group of complex organic macromolecules of which contained hydrogen, oxygen, nitrogen, carbon, phosphorus and sulphur, and is composed of one or more chains of amino acids.…

    Enzymes speed up the rates of most biochemical reactions by helping reactants interact with each other. Since enzymes are highly specific for a specific reaction, they only catalyze one or a few types of reaction. One of important enzymes in human body and many other animals is amylase that hydrolyzes starch, a major part of human diet for many people in the world. There is a variety of amylase produced from many sources in our body such as salivary glands in the mouth, pancreas cells, and small intestines (Scott, 2014). Amylase initiates the breakdown of starch which is a common plant polysaccharide composed of repeating glucose monomers into smaller subunits (Campbell et al, 2008).…

    In contrast to test tube 2, test tube 3 had a moderate amount of enzyme, but no substrate, so initially a substrate is not present to bind to the enzyme’s active site, and hence no products will be released (Reece et al., 2012). Test tube 4 ultimately alluded to an absorbance of 0.42, with equal quantities of reactants. This occurred as all starch molecules were converted to maltose molecules (Reece et al., 2012). Unlike other test tubes, tube 5 and 6 were not diluted with water, which increases the chances of a substrates binding to an enzyme’s active site and releases products at a faster rate (Reece et al., 2012). The enzyme to substrate ratio in test tube 5 was 1:2, and so the reading on the…

    In nature, there is no high GI food. High GI diet causes blood glucose to increase rapidly and so insulin level increases too. High insulin level is bad, because insulin can affect our metabolic process in the body. Some food has high water content such as fruits, consist of 95% of water, lean meat and fish. Although apple pie contains a huge amount of water, but it is unhealthy after processing as the water content has decreased, with high sugar content, starch and oil.…

    In addition, carbohydrates are the most important source of metabolic energy for human body, plants, and in animals that eat plants (Bruice 2011). The human body uses energy produced by carbohydrate for your cells, tissues and organs. The extra carbohydrates also stored in liver and muscles for when it is needed. Carbohydrates come in a variety of forms. The most common and abundant forms are fibers, sugars, and starches (nlm.nil.gov).…

    We will be looking specifically at the total calories and protein in relation to wound prevention and healing. Carbohydrates and fat are also essential in diet, but the biggest nutrition contributors to wound management are the total calories and protein. Micronutrients such as supplemental vitamins and minerals may be beneficial as well. We will also discuss these. Calories provide our bodies with energy during the hyper-metabolic and catabolic state which the body is in when a wound is present.…

    Determining Enzymes that Result to Mutation on the three Stages of Cellular Respiration Mary A Enriquez University of the Pacific November 11, 2014 2 Green Dr. Geoffrey Lin-Cereghino Abstract: The purpose of this lab is to determine which type of food source could possibly help strains grow on both permissive and restrictive temperature. Based on all the chemicals accumulating, we can determine the enzymes that are used to inhibit the three stages of cellular respiration. Introduction: For cells to successfully accomplish its task such as moving and reproducing, it needs energy. Most energy comes from the sun and the energy is stored in organic molecules. Cells release its stored energy by converting chemical energy in glucose…

    The bioavailability of key minerals such as iron, zinc and calcium is known to be significantly affected by the fiber, phytic acid, and tannin content of foods. Concentrations of these constituents are altered by various processing methods including milling, fermentation, germination (sprouting), extrusion, and thermal processing. Vitamins, especially ascorbic acid, thiamin and folic acid, are highly sensitive to the same processing methods. The time and temperature of processing, product composition and storage are all factors that substantially impact the vitamin status of our foods. Food processing and nutrition Almost all food is processed in some way before it is eaten.…
