General Biology I Lab (Bio 104) CRITICAL THINKING ACTIVITY I – Diffusion/Osmosis Name: Tonya Finch What are the 2 tests substances? 1. Potato starch 2. Sugar Water 3. Why did a color change occur in the jar water? Because IKI was added to give it an amber color (gold color). It iodine solution and this caused the color change. 4. What does the color change in #3 indicate? Water and IKI was in jar and the iodine caused the color change of the water. 5. Why did a color change

Reaction of Enzyme Amylase Research Question: How will changing the percentage of sodium chloride concentration affect the rate of reaction of enzyme amylase‚ measured using the absorbance of starch and iodine with a spectrophotometer. Introduction: Amylase is an enzyme that is involved in the human digestive process. Found in both the human pancreas and the human saliva‚ amylase breaks down starch into sugar so that large molecules can be easily digested1. Like all enzymes‚ amylase must be kept

Enzyme Lab Daniyal Abdali (Rachel Lee) (Sarina Dolch) SBI 3UI Mr. Vrabec October 20‚ 2009 Test #1 * Add a small piece of cracker in test tube #1 and add Lugol’s solution. Observation #1 * The cracker turned a black colour when the Lugol’s solution was added to it. This was a positive result‚ meaning that the cracker contains starch. Test #2 * Add a bigger piece of cracker in test tube #2‚ add 5 mL of Benedict’s solution‚ place in a boiling water bath‚ and record observations

Laboratory Report The Plasma Membrane I. Introduction The Plasma membrane is the edge of life‚ the boundary that separates the cell from its surroundings. It controls the traffic of materials in and out of the cell. (Reece‚ 2011). It is incredibly thin that is very vital in maintaining the integrity of the cell. Not only does the plasma membrane bind the other organelles‚ it also forms a dynamic structure which gives them their remarkable activity and selectivity. (Hickman‚ 2008). Diffusion

are looking for any alternative to lose weight (Anonymous 2011). If someone told you that they knew of a weight loss pill that actually works‚ would you consider it? A new study has proven that Carb Cutter pills are effective at preventing amylase‚ an enzyme that breaks down starch‚ from digesting starch. This then prevents starch from converting into glucose and then to body fat. The carbs that aren’t absorbed then pass through the digestive tract and are excreted. From what we hear‚ the pill

yellowish-green color. When there is a presence of something that is acidic the BTB indicator changes its color into yellow/green. So in this case‚ the water with BTB and carbon dioxide exhaled into the flask creates a carbonic acid. As an aerobic activity increase than the carbon dioxide rate increases as well. 2. By exercising more‚ one’s body requires more energy in their muscles. As the exercise becomes more continual‚ the aerobic respiration is primarily needed. Due to aerobic respiration there
