Lab 5 Cellular Respiration by Kris Layher Lab 5 Cellular Respiration Introduction Cellular respiration is the procedure of changing the chemical energy of organic molecules into a type that can be used by organisms. Glucose may be oxidized completely if an adequate amount of oxygen is present. The pressure due to C02 might cancel out any change due to the consumption of oxygen.
Meiosis Internet Lesson - use various sites to observe models of mitosis and meiosis Mitosis in an Onion Root - view slides and count the number of cells visible in each stage The Case of the Dividing Cell - case study where students learn stages of mitosis and meiosis, prokaryote versus eukaryote Modeling Chromosomal Inheritance - using beads and pipe cleaners to show how genes are passed from parents to offspring Linkage Group Simulation - pipecleaners are used to model crossing over Investigation: Mitosis - look at slides and real data from a cancer study to explore the role of P53 in the cell cycle Many of the activities listed in the investigation can be performed as classroom discussions, lectures, and animations.
DMD Electrophoresis Lab - uses electrophoresis to analyze DNA samples from a family to determine who are carries of duchenne muscular dystrophy DNA Extraction - extract DNA from a strawberry Electrophoresis equipment is expensive, local colleges and universities may be willing to loan you equipment DNA extractions are simple and require very little equipment Interactions Living systems from cells to ecosystems require free energy and matter to maintain order, grow, and reproduce, with organisms using various strategies to capture, use, and store free energy and other resources.
Energy Dynamics What factors govern energy capture, allocation, storage, and transfer between producers and consumers in a terrestrial ecosystem? Build an Ecosystem - grown plants and snails in jars and record changes in levels of CO2 by using btb as an indicator Virtual Lab: Population Biology - observe the competitive exclusion principle in populations of paramecium Where do Plants Get Their Food?
This experiment is a long term investigation and requires space and maintenance. Transpiration What factors, including environmental variables affect the rate of transpiration in plants?
AP Lab - Transpiration - using seedlings and plastic bags, measure the rate at which water is lost in different conditions The whole plant method in the Lab Guide may be a simpler way to complete this requirement, also using bags, strings and a seedling Investigation What environmental factors trigger a fruit fly response?
Isopod Behavior Lab - uses ispods rollypollys to investigate animal behavior Daphnia Heart Rate Lab - expose crustaceans to chemicals and measure responses This lab is simple and fun for the students, very little background information is needed to complete it and may be a good beginning of the year experiment Investigation Enzyme Activity How do abiotic or biotic factors influence the rates of enzymatic reactions?
Enzyme Lab - Using liver and hydrogen peroxide, observe enzyme actions in a variety of conditions temperature, acidity Enzyme Investigation on Substrate Concentrations - use yeast to create a catalase solution. Filter paper soaked in this solution will sink and then float in hydrogen peroxide as a measure of the rate of oxygen being produced This lab may fit better during the cell unit when discussiong organic molcules.The version of the browser you are using is no longer supported.

Bio 3A Lab. Scopes & Cells Page 1 of 13 BIOLOGY 3A LABORATORY Microscopes and Cells Objectives • To learn the proper use and care of compound microscopes • To learn staining techniques used in light microscopy • To prepare a wet mount • To determine the .
Combined effects of concentration and pressure that affect the flow of water. Water will flow from high water potential to low water potential. Bio 3A Lab: Biologically Important Molecules Page 3 of 11 (-COOH). The amino group on one amino acid is linked to the carboxyl group on an adjacent amino acid by a peptide bond.
The peptide bond forms through dehydration synthesis (Fig. 6). This bond is the site of action for the Biuret test for protein.
