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.
This acceptor is a blue color in its oxidized state, but upon the presence of SDH activity, the DCIP gets reduced and goes from blue to clear. This signals the transfer of electrons from SDHíFADH2 is present and thus means mitochondria must be present as well. However, in order for the electrons to go to DCIP we had to redirect the electrons from getting to
In cellular respiration, chemical energy that comes from fuel molecules is converted into ADP. ADP join with phosphate, then converts into ATP to form energy currency of cells. Cells release phosphate after consuming the ATP, which join with ADP to renew the cycle. The cycle state is called the glycolysis, electron transport and the acid cycle. They both provide energy that is used by plants, and recycle each other's "waste" for
For this assignment, a summary was to be written to explain the scientific article that I chose and relate that article to cellular respiration. The title of the article is: Revisiting the Relationship Between Exercise Heart Rate and Music Tempo Preference. The main purpose of this article related to cellular respiration is that music helps make a positive effect on a person, which increases the need to exercise which, in turn, raises the heart rate so this correlates to the purpose of the lab report. Preference is important in music so it can either be slow music or up-tempo music which would either increase or decrease the need to exercise more for an increase or decrease of heart rate. The conclusions of this article would be that the findings
We went to test how long it would take for the test tube to turn yellow and how much of the yellow liquid would deplete over the 48 hour time span. We filled the test tube with Bromothymol Blue Solution, allowing for the runner to blow into the liquid through a straw. After we completed the exercise part of the experiment, small plants were placed inside the test tubes and the test tubes were sealed away in a dark area. The objective was to see how exercise affects the disposal of carbon dioxide from cellular respiration and how light affects the absorption of carbon dioxide. According to the results, the longest time recorded was when the runner ran for a second time, while the shortest time was when the runner ran for the first time.
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
Homeostasis is the tendency within every living organism to maintain balance of its internal conditions in order to survive. Some examples of what our body regulates is hydration level, oxygen level, body temperature, blood pressure, and pH balance. The process of maintaining homeostasis comes from two different feedback loops, which are positive and negative feedback loops. A positive feedback loop brings a even greater change in the same direction, when the body senses a change (Raven). A negative feedback loop acts against the change sensed by the body, in order to retain the regular internal condition (Raven).
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.
Introduction Energy is vital for life. Oxygen is necessary for the production of energy in the form of ATP within cells in the process of oxidative phosphorylation and is sourced from the atmosphere through the process of ventilation. Breathing involves the movement of oxygen in and carbon dioxide out of the lungs in a cyclic pattern which alters in response to the body’s energy requirements or may be altered by health conditions. Respiration and lung function are determined primarily by the organs ability to change their size and volume in response to pressure changes within the thoracic cavity. Lung volume can be affected by many variables as described by Poiseulles law showing the relationship between flow of air and pressure difference,
During this process, molecules grab energy from electrons while moving around. This process occurs in the inner membrane of the mitochondria. Photosynthesis takes place within the chloroplasts of a plant cell. The chlorophyll within the chloroplast absorbs the light while carbon dioxide is grabbed from the air through an area of the leaves of a plant called the stroma. Water is also obtained through the roots of a plant which absorb water through root hairs.
Answer: The removal of an electron from a molecule, oxidizing it, results in a decrease in potential energy in the oxidized compound. The electron (sometimes as part of a hydrogen atom), does not remain unbonded, however, in the cytoplasm of a cell. Rather, the electron is shifted to a second compound, reducing the second compound. The shift of an electron from one compound to another removes some potential energy from the first compound (the oxidized compound) and increases the potential energy of the second compound (the reduced compound).
This occurs in both eukaryotic cells, as well as, prokaryotic cells. In the prokaryotic cells, it takes place in the cytoplasm; in the eukaryotic cells, it takes place in the mitochondria. Oxygen is vital for ATP production
Experiment 3: Cell Viability Testing and Counting with Trypan Blue Exclusion Method Anna Coretta R. Santos I. Introduction Cell viability assay plays a crucial role is in the cells of the cell culture. This assay can be used to identify the relationship of cell count from the cell’s behavior (Stoddart 2011). This test help researchers to determine the number of viable and non-viable cells in a cell culture. This assay helps in estimating the cell count of a cell culture and to determine if there is sufficient amount of viable cells in the cell culture that a person will use for future research (Riss et al. 2013).
