of basic units of matter called atoms. When atoms are bonded together they make up a molecule. Often associated with nonliving things are inorganic molecules‚ and associated with organisms are biomolecules. Today in lab‚ a series of tests were ran. Tested were the biomolecules of cells which are lipids‚ sugars‚ proteins and starch. The purpose of these tests were to test for the presences of cellular biomolecules. Some of the things that fat consist of are one glycerol and three fatty acids. Proteins

William Perez Cell Biology 2440 Lab on protein Myosin Proteins are chains of amino acids that perform the most important functions in living organism. Every protein will contain an amino group‚ carboxyl group‚ a different R group and an alpha carbon with two hydrogens. There are nine types of functions proteins can have‚ enzymes‚ motor‚ receptor‚ structural‚ storage‚ transport‚ signaling‚ and special purpose proteins(antibodies). There are four levels of protein structure‚ primary‚ secondary

leaves prevent the large loss of water from leaf due to transpiration. For the lab‚ I observed six leaves collected from six different plants growing sporadically around the school campus. Using clear tape‚ sticking it to the bottom of each leaf‚ applying pressure‚ and carefully peeling the tape off for an imprint of the leaf. I stuck the tape onto a glass slide and placed it under the microscope and observed the cells. Adjusting the magnification down 1000x‚ it is noticeable that the stomata were

Effects of pH on the Function of Enzymes Rena Mototani Glen Rock High School Advanced Biology 2014-2015 Effects of pH on the Function of Catalase Rena Mototani Problem: How does the pH of a cell affect the function of the enzyme catalase? Introduction In this lab‚ we experimented the effects of pH on the function of the enzyme catalase. Catalase is an enzyme that brings about the reaction by which hydrogen peroxide is decomposed to water and oxygen (Encyclopedia Britannica). The

the chemical reaction required for a specific action or nutrient. They can either launch a reaction or speed it up. Catalase is a common enzyme found in nearly all living organisms exposed to oxygen. It is a very important enzyme in protecting the cell from oxidative damage by reactive oxygen species (ROS). The catalase used in this experiment will come from five different sources: Spinacia oleracea (Spinach)‚ Brassica oleracea (Broccoli)‚ Solanum tuberosum (Russet Potato)‚ Malus domestica (Apple)

Name : Andi Nadya Amanda Period : 4 Grade : 11 Enzyme Lab Report Question How heats effect the length of reaction time of an enzyme? Hypothesis I think the heat will make the length of reaction time of an enzyme become slowly. Heat is one of a way to denature the substrate. It means the heat will break down the structure of substrate in order the reaction of enzymes that we activated into it become slowly. Method for Collecting Data First I will record the length of reaction time

the red cells grew on the CSM-Trp plates‚ than it would show that they are wild type for the TRP1 gene. All of the plates showed thick white colonies for the CSM-Trp plates. They should have been red because the ade2 colony streaked on the plate was red. They were still white because the adenine from the plate had not been exhausted. However‚ the cells are ade2- because they are red on all the other replica plates. The CSM-Ade plates are also a control. In order to ensure that the cells are ade2-
