Lab 7 – Cellular Respiration Objectives: • To be able to define cellular respiration and fermentation. • To give the overall balanced equations for aerobic respiration and alcoholic fermentation. • To distinguish between inputs‚ products‚ and efficiency of aerobic respiration and those of fermentation. • Understand the relationship between respiration and photosynthesis. Note: You should perform experiments as described in this handout‚ which are adapted from Starr and

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

around the plant as needed. The mesophyll cells have chloroplasts and this is where photosynthesis occurs. Respiration can be defined as the oxidation of the end products of glycolysis with the storage of the energy in the form of ATP. Cellular respiration occurs when oxygen is available‚ and the products are carbon dioxide and water. There are three main pathways in the cellular respiration process. These are: pyruvate oxidation‚ the citric acid cycle‚ and the respiratory chain. Pyruvate oxidation

ABSTRACT The effect of co-factor (MgSO₄) and the nature of substrate on the rate of cellular respiration in yeast were determined using two different set-ups. In the first set-up‚ two test tubes were used where one contains 7m and the other with 7 mL 0.2M MgSO₄ and both containing 7mL 10% yeast suspension. Here‚ data shows that the H₂O mixture showed higher amount of CO₂ evolved than MgSO₄. In the second set-up‚ six Smith fermentation tubes were used each containing different 15mL solution (starch

“Respiration” and “Photosynthesis” All life depends on two chemical reactions “Respiration” and “Photosynthesis”. These two processes are quite crucial because they are a source to nearly all life on Earth. Both of these processes are quite similar yet differentiate vastly. In this essay I’ll be comparing and contrasting “Photosynthesis” and “Respiration”. I’ll start by discussing what actually happens

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

and Type Of Sugar on Yeast Fermentation Lab Purpose: To measure and analyze the effects of various types and masses of sugar in an ethanol fermentation reaction with yeast. Introduction: Ethanol fermentation is a system in which hydrogen ions from NADH + H + are broken down in order to release the trapped energy and regenerate NAD+. In the absence of a mitochondria or oxygen ethanol is formed‚ which is typically found in bacteria and some yeast. Yeast fermentation has been used
