Also‚ understanding of which way substances will move passively through a deferentially permeable membrane depending on the concentration differences. We used PhysioEx software to examine diffusion. In these experiments we used different sized membranes as well as NaCl‚ urea‚ glucose‚ albumin‚ powdered charcoal‚ and KCl. The step by step process was used by the software so that

Effects of Temperature on the Formation of Cheese Curds This lab was performed in order to find what temperature the enzyme chymosin is most effective at forming cheese curds. An enzyme is a protein that acts as a catalyst to speed up biological reactions in cells. They work by lowering the activation energy and help to orient the molecules correctly. Chymosin was originally taken from the stomachs of calves‚ and was called rennet‚ and then purified to make rennin. Eventually to catch up with

Lab Report: Understanding Photosynthesis Gen Biology Lab Abstract: This lab was called photosynthesis: understanding photosynthesis. It is a highly complex process that needs to be broken down in many steps to understand how it works. This lab covers the big components in photosynthesis including carbon dioxide intake‚ light consumption‚ and varying pigmentation. Introduction: Photosynthesis is a huge concept to learn and understand in the field of biology. Plants have their own special

Dana Calderone Responses of Enzyme Activity from pH and Concentration Abstract Enzymes are the key to many of the chemical reactions that our bodies depend on to live. Without enzymes‚ we would not exist. These biological catalysts speed up the reactions as well as reduce the amount of activation energy needed to complete the process. Knowing how important enzymes are to us‚ it is important to realize what they require to function. They need select conditions and rates to work right. These conditions

standardize sodium thiosulphate for titration use. 2. To find out the concentration of Vitamin C in the tablet. Theory: This experiment involves titration of redox reaction. Redox reaction means reduction and oxidation. In which oxidizing agent and reducing agent are mixed and oxidize/reduce each other. One losses electron(s) and increase in oxidation number when is oxidized‚ and vice versa. In order to find out concentration of the ascorbic acid in the tablet‚ a redox reaction of it with iodine

Antibiotic Lab Report By: Sierra Toll Hour: 6 Title: The effects of antibiotics on the growth of Escherichia Coli Problem: How do antibiotics affect the growth of E coli? Hypothesis: If Penicillin is applied to the bacteria‚ then the zone of inhibition will be larger. Background: The purpose of this lab was to see how effective a certain antibiotic is to kill E coli. The lab tested three antibiotics‚ Penicillin‚ Erythromycin‚ and Neomycin. The zone of inhibition‚ which is the amount of space

Through this process‚ they are considered very unique because they are not altered or consumed within the reaction (Lab Manual 3 pg. 1). This is why enzymes are considered biological catalysts. They also do not alter the equilibrium of a chemical reaction nor the amount of free energy that is released (Lab Manual 3 pg
