Enzymes Introduction This study allows the investigation of enzymatic reactions behavior. An enzyme is a protein catalyst reaction by lowering the activation energy required for that reaction. The enzyme is unaltered at the completion of the reaction. In this stimulation the amount of product produced during the course of an enzymatic product produced during the course of an enzymatic reaction will be measured. Hypothesis 1: What is the estimate optimal of ph? Hypothesis 2: What is the estimate optimal of temperature

causing the body to not have enough acids in the urine. These factors are all very different‚ but are interconnected because an imbalance in any of these factors can lead to imbalances in other areas as well (Wise‚ 2010). The importance of this lab is to analyze factors that may affect urine concentration‚ pH‚ and rate of production (flow rate) though multiple scenarios over a period of 60 minutes. My hypothesis for the urine analysis experiment is that the urine volumes will increase because

AP ESSAY ANSWERS: 16-20 1. Information transfer is fundamental to all living organisms. For TWO of the following examples‚ explain in detail‚ how the transfer of information is accomplished. A) The genetic material in one eukaryotic cell is copied and distributed to two identical daughter cells. B) A gene in a eukaryotic cell is transcribed and translated to produce a protein. C) The genetic material from one bacterial cell enters another via transformation‚ transduction or conjugation

Analysis of Alum The objective of this lab is to run tests on a compound and analyze the substance itself‚ and then determine whether or not the compound is actually alum. Jill Cline Period 3 November 19‚ 2013 Laurel Hergenroeder and Sarinah Martelli Introduction/Purpose The purpose of this experiment is to run various tests on the substance called alum. (AlK(SO4)2 ∙ 12H2O). These tests like the process of filtration heating the solution will reveal things

AP Bio Lab Report Osmosis and Diffusion Introduction When a substance is released into an area‚ the random movement of its molecules results in a multitude of collisions. These collisions‚ in turn‚ lead to a dispersion of the molecules. The overall movement of the molecules will be from an area of high concentration‚ where there will be more collisions‚ to areas of low concentration‚ where the number of collisions will be much less. This process of dispersion will continue until there is no

Investigating Effects of duration of heating on permeability of beetroot cell membrane Introduction: Cell membranes contain many different types of molecules which have different roles in the overall structure of the membrane. Phospholipids form a bilayer‚ which is the basic structure of the membrane. Their non-polar tails form a barrier to most water soluble substances. Membrane proteins serves as channels for transport of metabolites‚ some act as enzymes or carriers‚ while some are receptors

Plant Pigments and Photosynthesis Problem: We are going to separate and identify pigments and other molecules from cell extracts through a process called chromatography. We will also test the theory that light and chloroplasts are required for light reactions to occur. Background: Pigments are chemical compounds which reflect only certain wavelengths of visible light. This is what makes them seem colorful. Many things contain pigments including flowers‚ corals‚ and even skin. More important than

The hypothesis for this lab was that Core B will be the least flexible due to a loss in water. Unfortunately‚ my results led my hypothesis to be incorrect. The results that were received was that Core C was the most flexible‚ Core B was somewhat flexible‚ and Core A was not flexible and stiff. Core A was the most non-adjustable due to it being hypertonic which means that the total concentration of all the dissolved solute particles is greater than the other solution. Core B was isotonic meaning

Courtney S. 4th Period SINKERS and FLOATERS Purpose:The purpose of this investigation is to provide an overview of photosynthesis and to design and conduct an experiment to test the factors that affect the rate of photosynthesis. Hypothesis:If 10 leaf discs are placed into 2 plungers and placed under a lamp the CO2 rate will speed up the process of photosynthesis. Materials: -Fluorescent lamp - Hole punch - 1 Sharpie marker -20 leaf discs -Syringes -12 mL cups Data Table Start 2 4 6 8
