Gold Fish Respiration Lab Report

In this lab we are measuring the amount of oxygen used in both germinating and non germinating peas. We are measuring the oxygen consumption by taking a reading of a respirometer submerged in two water baths. The first bath will be cold water and the second warm to determine the effect of temperatures on oxygen consumption. Our negative control will be glass beads to measure to increase or decrease in atmospheric pressure or temperature changes. There is a direct relationship between oxygen consumption and Carbon Dioxide produced, therefore the more O2 consumed the more CO2 produced. To keep the amount of CO2 produced from canceling out any pressure gained or lost from the consumption of

Cellular respiration is the chemical process in which organic molecules, such as sugars, are broken down in the cell to produce utilizable energy in the form of ATP. ATP is the chemical used by all of the energy-consuming metabolic activities of the cell. In order to extract energy from these organic molecules, cellular respiration involves a network of metabolic pathways dedicated to this task.

direct calorimetry. Furthermore, the amount of oxygen in the chamber reveals the amount of cellular respiration of the organism. While also, test the effects of decreasing oxygen, and later increasing the heat on the metabolic rate of goldfish. I hypothesize that an increase in temperature will increase their metabolic rate

It is usually a challenge to choose between the devil and the deep blue sea. Ordinarily, one has to consider one’s values as well as preferred consequences in order to make the better or best choice. In the short story, “What of This Goldfish, Would You Wish?” by Etgar Keret, Sergei Goralick faced a similar conundrum. As an aloof Russian expatriate fisherman in Jaffa, Israel, his only company is a magic three wish-granting fish. But having impulsively murdered Yonatan, Goralick had to decide whether to use his last wish to save the boy or keep his magic goldfish companion. Though he would have preferred the latter, Goralick made the better choice saving Yonatan as it matches his established humaneness and the consequences attached were more reasonable.

The Purpose of the Cell Respiration Lab is to find the different levels of Oxygen consumption, and Carbon dioxide production in organisms releasing different amounts of energy a relative period of time.

This lab deals with the transpiration rates in plants, specifically a tomato plant that was used for this experiment. Transpiration is when water leaves a plant through the stomata as water vapor while the stomata is capturing CO2 for photosynthesis. This experiment used three different scenarios: a tomato plant with a light shining on it, a tomato plant with wind blowing on it from a fan, and lastly a tomato plant with nothing acting on it. The hypothesis is that the rate of transpiration will be fastest with light, faster with wind, and slow with the control. This hypothesis was rejected because the rate of transpiration is as follows with the wind having the fastest rate: with light the rate was 7.60 mm/min, with wind 10.20 mm/min, and control 4.33 mm/min. The cause of the wind having a faster transpiration rate than the light may have been due to the surface area of the leaves on the tomato plants. The surface area of the leaves for the wind experiment is 8,124mm2, and for the light is 7,740mm2.By doing this transpiration experiment it helps one to see what happens in plants daily and understand why it happens.

Thirdly, chemical reactions keep us alive in the process of cellular respiration. Cellular respiration is the process by which the energy that we consume from our food is converted into energy that can be used by our cells. Cellular respiration is composed of a series of chemical reactions, including redox reactions. What are redox reactions? Simply put, they are reactions in which one molecule gives an electron to another molecule.

Will cellular respiration occur at a higher rate in seeds that store nutrients using oils or seeds that store energy using starches/carbohydrates?

The purpose of this experiment was to test the effect of the water temperature on a fish’s respiration rate. My hypothesis was: if the water temperature decreases, then the respiration rate will decrease because there is more dissolved oxygen in cooler water, thus, a fish would have a surplus of oxygen. I then did the experiment to prove this hypothesis. According to my group’s data table, when the fish was placed into warmer water, its respiration rate was 12 gill beats per 20 seconds. However, when the water temperature was lowered, the respiration rate also slowed down to 6 gill beats per 20 seconds. When looking at the class data table, the average respiration rate for fish placed in warmer water was 20 gill beats per 20 seconds, whereas

The Carassius auratus (goldfish) is an ectotherm and its physiologic functions are influenced by the shifts in their external temperature. In this experiment, we hypothesized the ventilation and oxygen consumption of the goldfish in a warm environment will have higher rates than goldfish in a cold environment. Based on the results, there was a statistical significance with a >99.5% confidence level in the ventilation rate of each treatment. According to a previous study by Szekeres et al. (2014), goldfish exposed to cold temperatures express a significantly lower ventilation rate than the goldfish in a control environment. However, there was not a statistical significance in the oxygen consumption rates of each treatment due to a <90% confidence

This experiment consisted of 3 respirometers, one with ants, one with radish seeds, and one with glass beads. Each with 4 pellets of KOH and a piece of cotton. They were placed in a water bath that was at 75 degrees fahrenheit. A bubble at the end of the respirometer was measured every five minutes, and this distance showed how well the organisms were respiring. The radish seeds were able to do the most cellular respiration in 25 minutes, with the ants being a close second, and the control respirometer of the glass beads doing the least.

The relationship between breathing and cellular respiration is that they are both forms of respiration since they both take in oxygen and expel carbon dioxide.

This experiment is conducted to determine whether the size of an animal did effect the rate of oxygen consume of the animal. Respiration rate, metabolism rate and rate of oxygen uptake or consumption all are defined as the oxygen uptake per hour per unit of body size. Basic law of thermodynamics did state that metabolic rate must decrease

water fish and saltwater fish are fully aquatic animals. Fully aquatic mean that both freshwater fish and saltwater fish will die shortly if they are taken out of water (Anderson et al, 2016).. Like most vertebrae, fish primarily require oxygen for metabolism. However, fish cannot obtain oxygen from air directly. Fortunately, water contains significant amount of dissolved oxygen. Fish obtain their oxygen from water through their gills (Grantly, Hastings & Walker, 2015). Both freshwater fish and saltwater fish have gills. Therefore, the respiratory process for freshwater fish and saltwater fish is similar.

Method: To test the effect of dissolved oxygen, 500ml of oxygenated aquarium water was filled in a 1 litre cylinder where the oxygen concentration was taken. A Corydoras aeneus, catfish was then placed in the cylinder and the number of breaths was observed and recorded at a given time period of 10 minutes. Where, within the 10 minute count 15 seconds x 3 times was used to observe the number of opercula beats this was recorded. Nitrogen gas was then bubbled into the water in the cylinder to lower the oxygen content to approximately 4mg/L. The number of breaths and opercula beats per hour were
