Cellular Respiration Lab Report

Our data recorded shows that the germinating peas did consume more oxygen than the non-germinating or the glass beads alone and that the cooler temperature did slow down the consumption of oxygen in the germinating peas. In both water baths the atmospheric pressure seemed to increase causing our reading to raise in our glass beads and non-germinating peas. This direct relationship in reading leads us to believe that the oxygen consumption in the non-germinating peas was minimal if any at all.

There are two types of cellular respiration, aerobic and anaerobic. Aerobic respiration occurs when there is oxygen present and in the mitochondria (in eukaryotic cells) and the cytoplasm (in prokaryotic cells). Aerobic respiration requires oxygen; it proceeds through the Krebs cycle. The Krebs cycle is a cycle of producing carbon dioxide and water as waste products, and converting ADP to thirty-four ATPs. Anaerobic respiration is known as a process called fermentation. It occurs in the cytoplasm and molecules do not enter the mitochondria for further breakdown. This process helps to produce alcohol in yeast and plants, and lactate in animals. Only two ATPs are produced through this process. In yeast fermentation is used to make beer, wine, and whiskey.

The first lab was conducted to analyze how germination affects the rate of cellular respiration in lima beans compared to dormant seeds. In order to

My lab partners and I performed an experiment that involved placing spinach disks into separate cups of distilled water (dH2O) and 0.2% sodium bicarbonate (NaHCO3) solution to examine photosynthesis in leaf tissue (Department of EEB, 2015). Discovering that the spinach disks quickly floated to the top of the 0.2% NaHCO3 solution and not in dH2O, we wondered if varied concentrations of carbonation would affect the rate of photosynthesis (PS). We tested this by halving the 0.2% NaHCO3 solution (using equal parts dH2O and 0.2% NaHCO3 solution to make 0.1% NaHCO3 solution). I hypothesize that if the spinach disks are placed in the 0.1% NaHCO3 solution, then they will have a slower PS compared to the disks placed in 0.2% NaHCO3. CO2

There are many procedures during this lab and many materials needed for an accurate analysis of data. First, fill a 100 mL graduated cylinder with 50 mL of water. Add 25 germinating peas and determine the amount of water that is displaced. Record this volume of the 25 germinating peas, then remove the peas and put those peas on a paper towel. They will be used for the first respirometer. Next, refill the graduated cylinder with 50 mL of water and add 25 non-germinating peas to it. Add glass beads to the graduated cylinder until the volume is the same to that of germinating peas. Remove the beads and peas and put on a paper towel. They will be used in respirometer 2. Now, the graduated cylinder was filled once again, determine how many glass beads will be require to reach the same volume of the germinating peas. Remove the beads and they will be used in respirometer 3. Then repeat the procedures used above to prepare a second set of germinating peas, dry peas and beads, and beads to be used in respirometers 4,5,and 6, the only difference is the temperature of the water.

The type of sugar affects the rate of cellular respiration because each sugar is classified as either a monosaccharides, disaccharides or polysaccharides. The data from this experiment was collected by the amount of carbon dioxide produced from the type of sugar that was used. The data was then analyzed using a line graph. Data was also collected in class averages. There were three sugars in this experiment, glucose, lactose, and fructose. An example of a monosaccharides would be glucose and fructose. The slope for glucose should be about 283.07. The slope for fructose should be about 269.77. Second, an example of a disaccharides would be lactose. The slope for a disaccharide in this experiment should be about 67.055. The data shows that

The CO2 production was measured with a CO2 meter (+/- 1ppm), in order to determine the rate of anaerobic cell respiration in yeast.

Purpose: The purpose of this lab was to determine how light affected the amount of oxygen gas produced over time. The amount of oxygen gas consumed during cellular respiration and produced during photosynthesis was measured. The experiment also determined the rate of respiration and photosynthesis of a plant.

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.

At the end of our experiment sucrose was actually the winner of the most carbon dioxide however; DR.

All living organisms need the energy to perform the basic life functions. Cells use a process called cellular respiration to obtain the energy needed. In cellular respiration, cells convert energy molecules like starch or glucose into a cellular energy called Adenosine triphosphate(ATP). There are two types of cellular respiration which include: Aerobic and Anaerobic respiration. In aerobic respiration, cells will break down glucose to release a maximum amount of ATP this takes place in the presence of oxygen. Aerobic also produces carbon dioxide and water as waste products and it takes place in the mitochondria. on the other hand, anaerobic respiration, a metabolic process, also produces energy and uses glucose, but it releases less energy and does not require the

All cells store energy in a molecule called adenosine triphosphate (ATP) in the aerobic respiration process oxygen is required to generate adenosine triphosphate (ATP). This compound contains three phosphate groups, but can release energy by losing one of these to form adenosine diphosphate (ADP). ADP can also gain a phosphate group to become ATP, and store energy. Glucose, the starting point for all processes, the more complex sugar molecules in food is first broken down to the simplest forms, glucose. Glucose is then broken down using the glycolysis stage, which takes place in the cytoplasm, or cellular fluid, and is common to both anaerobic and aerobic

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.

Aerobic respiration is the way toward delivering cellular energy involving oxygen. Cells separate the food in the mitochondria in a long, multistep prepare that produces 32 ATP. The initial phase in is glycolysis, the second is the citric acid cycle and the third is the electron transport system. Germination is one of such procedures that make use of aerobic and in light of the fact that specific variables can influence aerobic respiration, it would likewise influence germination. The chemical reaction for aerobic respiration is:
