Colleen Hamilton AP Lab 4: Determining the Rate of Cellular Respiration of Peas at Varying Temperatures and Stages of Germination I. Purpose and Intro The purpose of this lab is to determine the rate at which germinating peas respirate at varying temperatures and stages of germination. Cellular respiration is the set of metabolic reactions and processes that takes place in an organism’s cells in order to create ATP from sugar. It occurs in the mitochondria and comprises three stages: glycolysis

Abstract The hypothesis states that plants respire at a faster rate if they are exposed to wind‚ opposed to no wind. This was tested by putting one plant in water in front of a fan and the other plant in water‚ but with no fan. The results showed that the plant in front of the fan transpired more. However‚ since the plant blew cold air it affected the rate of transpiration and altered the experiment. Overall‚ this experiment supports the hypothesis that wind makes plants transpire more.

Lab 5Cellular Respiration Introduction: Cellular respiration is an ATP-producing catabolic process in which the ultimate electron acceptor is an inorganic molecule‚ such as oxygen. It is the release of energy from organic compounds by metabolic chemical oxidation in the mitochondria within each cell. Carbohydrates‚ proteins‚ and fats can all be metabolized as fuel‚ but cellular respiration is most often described as the oxidation of glucose‚ as follows: C6H12O6 + 6O2 → 6CO2 + 6H2O + 686 kilocalories

Principles of Cellular Respiration Ashley Flannigan November 5th‚ 2013 Professor Ryan BSC2010 Lab Fall 2013 2220 ABSTRACT Students in a Biology 1 lab class constructed an experiment on Cellular Respiration by investigating the effects of temperature on crickets’ metabolic rate. By following the following procedures out of the Lab Manual‚ the students were able to find an almost accurate representation of the crickets’ cellular respiration rate under various temperatures in order to

Investigate the effect of temperature on the rate of respiration of various parts of plants (germinating seeds and dormant (non-germinating) seeds)‚ by measuring the oxygen consumption and change in gas volume of respirometers containing either germinating or non-germinating seeds at different temperatures to measure the rate of respiration of these beans at different temperatures. Hypothesis 1.Germinating seeds have a higher rate of respiration as compared to non-germinating seeds and the glass

transport oxygen rich blood from the alveoli back to the heart. Inspiration (the process of inhaling) begins as the external intercostals and diaphragm contract. When this happens‚ the lungs expand. After this‚ negative pressure is used to facilitate respiration. So‚ air moves from an area of higher pressure‚ which is the air‚ to an area of lower pressure in the lungs and aveoli. During inspiration the diaphragm and intercostal muscles contract. The diaphragm moves downwards‚ while the intercostal muscles

AP Biology I Investigation 6 AP Bio: Lab 6 Cellular Respiration Introduction Some knowledge that is needed before performing this lab are as follows: First of all‚ cellular respiration is the metabolic processes whereby certain organisms obtain energy from organic molecules. This process includes glycolysis‚ the Krebs cycle‚ and the Electron Transport Chain. Glycolysis is a process that takes place in te cytosol and it oxidizes glucose into two pyruvate. Glycolysis also makes ATP and NADH. The

Badminton provides a good model for investigating the interplay between aerobic and anaerobic metabolism and the effect of nutrition‚ heat and fatigue on performance. Badminton requires the performance of work in the nature of sprints‚ stops and starts‚ jumps‚ leaps‚ lunges‚ rapid changes of direction‚ twists and turns and a variety of strokes

highest respiration rate of 455 ppm/min. Sucrose is second with 391 ppm/min‚ then fructose with 231 ppm/min and lastly lactose with 92 ppm/min. We can see a clear trend‚ that glucose had the highest rates and that lactose was the lowest‚ so we see a clear downwards sloping trend‚ which was also expected. This suggests that yeast respires best with glucose instead of sucrose fructose or lactose. To explain this process‚ we must first understand how sugar affects yeast growth. First of all yeast is a

ANAEROBIC DIGESTION ON BIODEGRADABLE WASTE FOR METHANE GAS CAPTURE BIODEGRADABLE WASTE: Biodegradable waste is a type of waste‚ typically originating from plant or animal sources‚ which can be decomposed by other living organisms. Biomass‚ manure‚ sewage‚ municipal waste‚ green waste and plant materials are some of these common biodegradable waste. ANAEROBIC DIGESTION: This is a series of biological processes in which microorganisms breakdown biodegradable materials in the absence of oxygen
