Diffusion & Cell Size Lab Background The absorption of nutrients‚ excretion of cellular wastes‚ and the exchange of respiratory gasses are life processes which depend upon the efficient transport of substances into‚ out of‚ and throughout living cells. The process of diffusion can be easily visualized by adding a drop of blue food coloring to a glass of water. Initially‚ the food coloring remains in a small area in the water‚ dying it a dark blue. Over time‚ the molecules of food coloring

Measuring the rate of cellular respiration in yeast within different types of sugar Aim/Reasearch Question: How can the rate of cellular respiration be measured to find out if sucrose‚ dextrose‚ lactose‚ or maltose lets the yeast to respire more than others. Hypothesis: I think‚ dextrose yeast solution will respire the most number of bubbles because it is the simplest sugar to break. Materials: * Knut * Dropper * Graduated cylinder (100ml) * Warm water * Yeast Solution * Sucrose

hypotheses based on predictions questions. First‚ yeast will metabolize sugar and produce a gas. This is because yeast is a living organism and all living organisms like yeast must use energy (such as sugar) to obtain energy. Yeast will metabolize sugar and gives off carbon dioxide as a by-product. For the second hypothesis‚ we were expecting that yeast will produce a gas when sugar is available. For the third hypothesis‚ we did not expect yeast to produce a gas when no sugar or other food is available

Oxygen Animals are Producing/ Consuming Introduction Every cell needs a source of energy in order to perform their daily functions. However the process to get this energy is different for plant and animal cells. Plants cells undergo a process called photosynthesis where light energy from the sun is used to convert carbon dioxide and water into glucose and oxygen. For animal cells‚ the process is known as cellular respiration by which cells break down complex molecules‚ such as sugars‚ to release carbon

Cellular Respiration and Fermentation Facts to Remember 1. Cellular respiration is a catabolic series of reactions. 2. All living forms conduct some form of cellular respiration‚ either aerobic or anaerobic. a. Aerobic is in the presence of oxygen b. Anaerobic is in the absence of oxygen or none oxygen requiring. 3. The starting molecules consist of the biological molecules with carbohydrates (monosaccharides) as the first choice. The order of use is given below. a. Carbohydrates b.

Cellular Respiration Cellular respiration is basically what cells do to break down sugars into a form that the cell can utilize as energy. Cellular respiration takes in food and uses it to create ATP. ATP is a chemical which the cell uses for energy. The are two forms of cellular respiration‚ aerobic and anaerobic respiration‚ in which will be explained. Regular cellular respiration is aerobic‚ meaning that it requires oxygen‚ but some simple organisms can only do anaerobic cellular respiration‚

discovered all the time‚ yet all living organisms perform one or both of two very important processes; cellular respiration and photosynthesis. Photosynthesis is performed by plant organisms and some bacteria‚ and cellular respiration is performed by all living organisms. These two processes are reliant on each other. Photosynthesis creates oxygen‚ which is used in cellular respiration. Cellular respiration in turn creates carbon dioxide‚ which is an important “ingredient” in the process of photosynthesis

Both photosynthesis and cellular respiration are the main pathways of energy transportation in organisms. However‚ the reactants and the products are exact opposites in photosynthesis and in cellular respiration. In photosynthesis‚ cells take in carbon dioxide (CO2) and water (H2O) by absorbing energy from the sun‚ and then the cells release oxygen (O2) and store glucose (C6H12O6). The formula of photosynthesis is: Light energy 6CO2+6H2O → C6H12O6+6O2

type of respiration in animals. All plants and animals do cellular respiration. Respiration is the release of energy‚ which occurs in the living things’ cells. Cellular respiration is the use of glucose and oxygen to yield ATP which is usable energy. Glucose is broken down into glycolysis‚ which is then used to make ATP. ATP is the usable form of energy which allows organism to function. Almost all organisms do cellular respiration‚ others do anaerobic respiration. Cellular respiration is a part
