Animal metabolism consists of the utilization of nutrients absorbed from the digestive tract and their catabolism as fuel for energy or their conversion into substances of the body. Metabolism is a continuous process because the molecules and even most cells of the body have brief lifetimes and are constantly replaced, while tissue as a whole maintains its characteristic structure. This constant rebuilding process without a net change in the amount of a cell constituent is known as dynamic equilibrium (Grolier1996). In the combustion of food, oxygen is used and carbon dioxide is given off. The rate of oxygen consumption indicates the energy expenditure of an organism, or its metabolic rate (Grolier1996).
The beet Lab experiment was tested to examine bio-membranes and the amount of betacyanin extracted from the beets. The betacyanin is a reddish color because it transmits wavelengths in red color and absorbs most other colors. The membrane is composed of a phospholipid bilayer with proteins embedded in it. The phospholipid bilayer forms a barrier that is impermeable to many substances like large hydrophilic molecules. The cells of beets are red and have large vacuoles that play a big role for the reddish pigment. This experiment aimed to answer the question, “How do cell membranes work?” The hypothesis we aim to test is: Cell membranes work as a fluid mosaic bilayer of phospholipids with many embedded proteins. We predicted that the 50% Acetone will break down the most betacyanin. Our hypothesis was proven wrong by our data collected. We could test our predictions by doing the experiment multiple times and compare the

Permeability of Beetroot Cell Membranes. An experiment to investigate how temperature affects the Permeability of beetroot cell membranes. Interpretation of Results:. 0 ° C 20° C 30° C 40° C 55° C 0.24 0.28 0.75 0.79 0.22 0.26 0.35 0.41 0.81 From 0°C to 30°C there is a gradual increase in absorbency which shows that as the temperature increases it is denaturing the cell wall and cell membrane and allowing the beetroot pigment to leek out into the distilled water.
the same way as it does potato. I would also widen the range of sugar
Osmosis in Carrots Background Osmosis is the diffusion of water from a dilute solution to a more concentrated solution through a partially permeable membrane, which allows the pass of water molecules but not solute molecules. [IMAGE][IMAGE][IMAGE][IMAGE][IMAGE][IMAGE][IMAGE][IMAGE]If a cell is placed in a less concentrated solution water enters because the less concentrated solution will have a high concentration of water than the inside of the cell. Once the cell takes in maximum water the cell becomes turgid. If the cell was to be placed in a high concentrated solution, water would leave the cell because the cell would contain a low concentrated solution. So in the low concentrated solution there will be a high concentration of water and in the high concentrated solution there will be a low concentration of water.
The effect of temperature on the beetroot membranes Aim of the research: The aim of this investigation is to determine what kind of effect will the increasing temperature have on the plasma membrane of a beetroot cell. Introduction The beetroot contains a red pigment that is kept in the cells by the membranes. If the membranes are damaged, the pigment “betalain” will leek out. The amount of pigment that leeks out can be assessed, as “betalain” will colour any water that surrounds the cell.
Introduction: Respiration, commonly known as the inhalation, exhaling or breathing, has a little known definition. This is the definition that involves the cellular level of eukaryotic cells. Cellular respiration may best be described by the following equation: C6h1206+602-6CO2+6H20+36ATP. ATP is the energy needed for a cell to function as part of cellular respiration. ATP is needed to power the cell processes.
Investigating the Effect of Sugar Solution on the Weight and Size of Potato Cells Aim: To investigate whether the different concentration of sugar solution will affect the weight and size of the potato cells. General background information: Osmosis is defined as the movement of water or any other solution's molecules from an area in which they are highly concentrated to a region in which they are less concentrated. This movement must take place across a partially permeable membrane such as a cell wall, which lets smaller molecules (E.g. water) through but does not allow larger solute molecules to pass through. The molecules will continue to diffuse until the area in which the molecules are found to reach a state of equilibrium, meaning that the molecules are equally distributed throughout the cell, with no area having a higher or lower concentration than any other hence equal. Hypothesis/prediction: For this particular investigation I believe that the lower the concentration of the sugar solution in the test tube the mass of the potato will be greater and the longer the potato cells will be.
The Effect of Temperature on the Permeability of Beetroot Membrane Analysis The graph shows the colorimeter readings increase as the temperature increases, they increase by the most at higher temperatures. This is shown by a smooth curve. This means that the beetroot samples release more dye at higher temperatures. This is because higher temperatures cause the membrane structure to break down. The membrane structure: Membranes have two layers of molecules called phospolipids to make up their structure.
Determining the Concentration of the Cell Sap in Potato Storage Tissue Aim: To determine the concentration of the cell sap in potato storage tissue. By using Osmosis, determine what the sugar concentration of cell sap is. Prediction I predict that the potato segment in the distilled water will definitely gain in weight because the solution outside it has a much higher concentration of water then in the cell sap meaning Osmosis will occur and the potato segment take in water. I predict that 0.2M sugar solution will also gain weight because it still has quite a high concentration of water outside the potato. The potato in the 0.4M solution will gain weight but the potato in the 0.6M and 0.8M solutions will lose weight.
Osmosis in Potato Tubes Osmosis: Osmosis is the movement of water molecules through a semi-permeable membrane from a high concentration to a low concentration. Diagram: [IMAGE] [IMAGE] Aim: To see the effects of different concentration of sugar solution on Osmosis in potato tubes. Key factor: In the investigation we change the sugar solution from: 0%-10%-20%-30%-40%-50% this is the independent variable; the dependant variable is the change in mass. Prediction: I predict that all the potato tubes in pure water or low concentration sugar solution will swell because water enters their cells by osmosis.
