a low water temperature a fish slows down and so do its metabolic activities and when water temperatures are high‚ fish speed up and their metabolic processes increase as well. Proteins and enzymes are also affected by temperature changes. Oxygen is essential for the production of ATP from nutrients in cells; consequently oxygen must be delivered to a cell in sufficient amounts. Within fish‚ the counter-current exchange system allows for the efficient extraction of oxygen from the water by the gills

Jane Doe Bio Lab IT: Morgan Billick September 4th‚ 2010 Ventilation and Oxygen Consumption Results Oxygen Concentration Oxygen concentration in water can be altered by the conditions it is exposed to. For instance cold water has a higher oxygen concentration than warm water. In our experiment we were able to observe the change in oxygen concentration of water at two different temperatures (15C and 25C) with a fish in each environment. Our results proved that the starting oxygen concentration

goal of this study was to measure the oxygen consumption of goldfish in an ambient environment and dark environment and calculate if there was any difference in metabolism based on oxygen consumption. The experimental hypothesis was that the metabolic rate of the goldfish as measured by oxygen consumption differs in a dark environment than in an ambient environment. The null hypothesis was that the metabolic rate of the gold fish as measured by oxygen consumption does not differ in darkness versus ambient

Ventilation and Oxygen Consumption in Fish Sally Ming Bio 102- PR# 2 12/12/12 Abstract Goldfish (Carassius Autarus)‚ when subjected to warm temperatures will have a high rate of ventilation compared to those exposed in colder environment. In a class experiment‚ we observed and recorded the effects of water temperature at [25 C] warm and [15 C] cold on ventilation and consumption rates in goldfish. For one hour at 15min intervals we observed differences in both ventilation and consumption

muscles‚ the muscles that increase the rate of ventilation receives the nerve impulses. Through anaerobic or aerobic respiration‚ ATP‚ which acts as an energy source‚ is generated. Intensity of exercise is closely related with the respiratory. Respiration increases during exercise due to the metabolic requirements of the activated muscles. This is to allow the exchange of oxygen and CO2 in lungs. As seen Fig. 1‚ there is a steep increase in ventilation at the starting point of exercise. This occurs

Chemical Report The chemical I will be writing this report on is oxygen. The name oxygen comes from the Greek word “oxygens‚” which means “acid producer”. Dictionary.com defines oxygen as “a colorless‚ odorless‚ gaseous element constituting about one-fifth of the volume of the atmosphere and present in a combined state in nature.” Oxygen has many uses today. First‚ oxygen is used by people‚ plants‚ and animals in the respiration process. Tanks of oxygen are used in the healthcare field to treat

Function Jeremiah Schmidt - 17456597 ------------------------------------------------- INTRODUCTION The aim of practical 3 under the respiratory control subsection was to investigate the effects that hyperventilation and rebreathing have on ventilation rate and breaking point and to observe the effect of carbon dioxide (CO2) on water pH (School of Science and Health 2012). The results from respiration rate and breaking point were then compared to the different sexes and further with those whom

(Figure 1). For the next test‚ Dissolved Oxygen‚ we also created a bar graph to compare the values for the control and experimental groups. These results came in as statistically significant too‚ as the p-value was very low at .004. As for the overall mean values of the two groups‚ we found that the control group was oversaturated with oxygen at 102.78% while the experimental group was also slightly oversaturated at 101.55%.

through a process called respiration or breathing. Aerobic respiration‚ also known as aerobic metabolism‚ occurs when oxygen is taken into the body and sent to all its cells; the oxygen is then used to break down food for energy (White and Campo 2008). Respiration can be experienced through several structures such as the lungs‚ tracheae‚ gills‚ and integument in order to obtain oxygen. All organisms that experience respiration are either endotherms or ectotherms. Ectotherms are animals that depend

102 Lab Report: Ventilation and Oxygen Consumption in Fish Methods: The lab consists of two experiments repeated over a period one hour with fifteen minutes interval‚ in order to determine the effect of weight and temperature on ventilation and oxygen consumption of Carassius auratus‚ commonly known as goldfish. Each experiment was carried out by five groups. Measurement of ventilation was determined by recording operculum movement of the fish. Oxygen consumption was measured using oxygen probes
