This scientific report will be based on cellular respiration‚ or fermentation. In specific‚ how the type of sugar affects the rate of fermentation. The aim of this experiment was to find which type of sugar was best suited to produce ethanol. In the experiment‚ four different sugars were used‚ they included sucrose‚ glucose‚ lactose and fructose. This research is still relevant today‚ as alcohol is still consumed and is required on a large scale. This makes it crucial to companies to find the best

The effects of surface type on the number of bounces Question How does the surface type affect the number of bounces of a tennis ball? Hypothesis If we drop the ball on a softer surface‚ then it will bounce less times than on a hard one. Materials List Floor Jacket Desk Binder (x2) Tennis ball Slow motion camera (phone) Metre stick Procedure Set up equipment (listed above). Drop the ball from a height of 1 metre on the first surface. Film the drop (in slow motion). Count and record the bounces

The effects of different wavelengths of light on the rate of photosynthesis Introduction This experiment was performed to investigate the effects of different wavelengths of light on the rate of photosynthesis. If a multiple colored film petri dishes are place under a 50 watt lamp‚ then the rate of photosynthesis will be greater for those with red‚ blue and clear film‚ than those with green and black film. We believed the petri dishes with the red‚ blue and clear film would produce the best

completed to determine the rate in which fermentation occurs in different sugars and to compare the rate of cellular respiration in germinating and non-germinating soybeans. Fermentation breaks down sugars for a source of energy. Cellular respiration is the process used by cells to produce energy from nutrients. This process allows sugars and foods to be broke down in order to obtain energy from adenosine triphosphate (ATP). Cellular respiration is vital for survival of cells. Oxygen‚ which acts as the

SC.L.18.9 Understand the interrelationship of photosynthesis and cellular respiration. Problem Statement: Does Exercise let you Breath more CO2? Intro: Cellular respiration allows organisms to use energy stored. The materials produced are carbon dioxide and water. The body has stored away from the foods we eat in the form of glycogen‚ for the energy required to contract muscles movement. Lactic acid fermentation is glucose and sugars. The more energy we use the more CO2 we exhale. The Bromothymol

Mitochondria - Take in glucose via proteins that pass the plasma membrane and after it journey through the cytoskeleton to the mitochondria inside the cytoplasm. Endoplasmic Reticulum - Both ER types are covered in making essential cellular segments. For the most part in charge of the combination and handling of proteins that are either emitted from the cell or that end up stuck in the plasma film. The lipids made in the SER are joined with phosphorous to make phospholipids‚ the most inexhaustible

specific conditions to function‚ thriving at temperatures between 29°C-40°C‚ with an optimal temperature of 37 °C. Above 37°C‚ rennin molecules increase in energy causing the rate of reaction to increase‚ becoming denatured at approximately 60°C. Below 37°C‚ the reduced energy level results in fewer collisions and the rate of reaction and activity of rennin decreases. (7) The optimum pH for rennin is pH 3.4 (8) as it mimics the gastric juices and acidic conditions of the stomach‚ however again rennin

the cell appeared smaller after being exposed to starch solution was because water molecules move out of the cell because the concentration of water inside the cell was greater than outside the cell. I believe this for a few different reasons. We were given 3 different explanations to explain why the cells appear smaller after being exposed to sugar water. These include: That the sugar molecules are not able to enter the cell‚ but the sugar molecules push on the cell membrane making the cell appear

some physicians in the 1940’s to help patients lose weight. This unsafe method was abandoned after a few patients died. DNP uncouples the chemiosmotic machinery by making the lipid bilayer of the inner mitochondrial membrane leaky to H+. Explain how this could cause weight loss. In chemiosmosis‚ NADH are passed along the electron transport chain‚ with energy used to pump protons across the inner mitochondrial membrane. As the protons are transferred across‚ a proton gradient is created. These

A potato will be the substance used to determine how different temperatures affect this enzyme. This experiment has a control‚ independent‚ and dependent variable. The control variable is the size of the filter paper‚ the amount of potato in the experiment‚ and the amount of hydrogen peroxide used. The independent variable
