During this experiment, mitochondria were isolated from 20.2 grams of cauliflower using extraction buffer, filtration through Miracloth, and centrifusion. Twelve samples containing various volumes of mitochondrial suspension, assay buffer, DCIP, sodium azide, and citric acid cycle intermediates were prepared to be read by a spectrophotometer. The inclusion of the dye DCIP allowed for the absorbance of the reactions between the mitochondrial suspension and the TCA cycle intermediates succinate, malonate, and oxalate to be measured, as DCIP turns from blue to colorless as the activity of succinate dehydrogenase increases. Experimental Findings Increasing the number of mitochondria in the reaction did increase the reduction of DCIP relative to the amount of mitochondrial suspension present.
In this experiment we are observing how colder water is associated with the respiration of goldfish. Respiration, also known as breathing, is the process in which the body exchanges gasses and supplies oxygen. Goldfish use their gills to receive oxygen and get rid of carbon dioxide. Oxygen is an essential part to life because it is broken down to create ATP. ATP gives the goldfish energy to carry out it’s everyday goldfish activities.
Purpose/Question Does higher or lower than natural cricket environment temperatures affect carbon dioxide emissions from cellular respiration? Background A cricket’s ideal living temperature is about 21.1 to 32.2 degrees celsius, depending on the breed and location. If a cricket is in an environment that is at an ideal temperature, its heart rate will most likely speed up and it will be much more active, which will speed up the cellular rates of respiration. This is because crickets are ectothermic, or cold blooded.

The first step of the creation of verdigris was preformed using the following reaction (1): 4CuSO4*5H2O(aq) + 6NH3(aq) CuSO4*3Cu(OH)2(s) + 3(NH4)2SO4(aq) + 14H2O(l) Based on this chemical equation, four moles of hydrated copper sulfate reacted with six moles of ammonia to produce a precipitate of copper sulfate tribasic along with aqueous ammonium sulfate and liquid water. It was known that a chemical reaction was occurring when the ammonia was being added via the color change from light blue to dark blue. The precipitate formed from this solution was acquired via vacuum filtration, which involved the solution being separated from the precipitate via air pressure flowing out of the flask. The air pressure flowing out of the flask was caused by a faucet that was running water which was attached to a tube that was attached to the collection flask.
Year 11 Stage 1 biology Bird Beak Summative Practical SACE# 798905X Aim: The aim of this practical investigation is to simulate the idea of adaption and evolution in times of drought in both valley and mountainous areas, through four common utensils representing four different types of bird beaks. Common dietary foods consumed by birds were substituted for toothpicks and beans. Hypothesis: In the valley were the toothpicks are found, the tweezer beaked bird will be the most affective at collecting food. This is due to the toothpicks resembling that of worms.
Abstract The purpose of this experiment is to test for mitochondrial activity by isolating different organelles using the differential centrifugation process. Studying mitochondria is extremely important because they control the death and life of the cell by regulating the apoptotic signals (Frezza et al 2007). Also they are responsible for the metabolic reactions (aerobic respiration) and the production of ATP (Frezza et al 2007). Three hypotheses were formed based on my knowledge.
Cell Respiration Lab Research Question What is the optimal temperature for germinating pea-seeds where the rate of respiration is the greatest? Background Information Cell Respiration refers to the biochemical process conducted by the cells of an organism that combines glucose and oxygen to produce energy in the form of ATP, along with two by-products, water and carbon dioxide. The equation representing this chemical reaction is shown below. C6H12O6 + 6 O2 6 CO2 + 6 H2O
My doctor said my vital signs showed I had a normal temperature of 98.6, a blood pressure of 140/90, a heart rate of 100, and an oxygen level of 80%. I took multiple tests, such as a chest examination where my doctor used a stethoscope to listen to my chest. Apparently I have crepitation’s. He can also hear me wheeze, and that it is clear I have difficulty breathing. I also took a spirometry test.
The Effect of Sugar Concentration on CO2 Production by Cellular Respiration in Yeast Introduction In this lab, our main focus was to find how sugar concentration affect yeast respiration rates. This was to simulate the process of cellular respiration. Cellular respiration is the process that cells use to transfer energy from the organic molecules in food to ATP (Adenosine Tri-Phosphate). Glucose, CO2, and yeast (used as a catalyst in this experiment) are a few of the many vital components that contribute to cellular respiration.
Oxygen presence and availability will differentiate which type of cellular respiration will be used. In aerobic respiration it will involve the oxygen to produce energy needed for the cells to work in the form of adenosine triphosphate (ATP). This includes water and carbon dioxide being the by-products. However if oxygen is not present it will be anaerobic respiration, where the cells are still able to produce the energy that’s needed but a lot less amount.
Your breathing rate is regulated by neural and chemical mechanisms. Respiration is controlled by neural messages from the brain to nerves that stimulate respiratory muscles. The main respiratory muscle is the diaphragm, which is controlled by the phrenic nerve. The rate, at which the nerves are sent messages from the brain, is controlled by the level of oxygen and carbon dioxide in the blood. There are chemoreceptors in the brain and the heart that sense the amount of oxygen, carbon dioxide and acid present in the body.
The three stages of cellular respiration are glycolysis, the citric acid cycle and the electron transport chain. To explain cellular respiration, it is the aerobic harvesting of energy from food, the energy-releasing breakdown of said food, and the storage of potential energy that cells use to accomplish their respective missions (Simon, 2017). The stage I decided to focus on is glycolysis. Glycolysis happens in the cytoplasm and the actual process involves the halving of one glucose molecule into two pyruvic acid molecules (Simon, 2017). After the glucose molecule splits, some ATP is created as well as high-energy electrons carried by a NADH molecule, which is just a NAD+ molecule that picks up electrons.
Cellular Respiration One of the main essentials of life that all organisms need in order to function in our world is, energy. We receive that energy from the food that we eat. Cellular respiration is the most efficient way for a cell to receive the energy stored in food. In cellular respiration, a catabolic pathway, which breaks down the molecules into smaller units, in order to produce adenosine triphosphate, also known as, ATP. ATP, is used by cells in the act of regular cellular operations, it is a “high energy” molecule.
