The cell functions much in the way a city does. Although it may be an old analogy‚ it may be one of the best. Following is a list of cell parts and how their function is similar to functions of a city or town. The cell membrane is the city limits of our city. Outside of the city limits‚ the local government has no jurisdiction‚ but inside those limits‚ people are subject to the “laws of the land”. The nucleus – This is the place where direction is given and DNA is sent from. This would

The effect of varying temperature on thee Rennin enzyme Abstract The purpose of this experiment was to see what affect different temperate had on the reaction rate of the enzyme rennin. The experiment was performed by placing test tubes filled with renin and milk into water bath which was heated or cooled to one of the temperatures trialed. The hypothesis justified because it found because it though data that the enzyme reacted faster with the 45° temperate because it was

Plasma membranes are selectively permeable. The purpose of this experiment is to reveal how a form of diffusion in a semipermeable membrane works by creating a real life simulation of a semipermeable plasma membrane. This is done by building an imitation of a caterpillar’s digestive tract using dialysis tubing and glassware. The first material in this experiment is a small beaker representing the head and crop of the caterpillar. This beaker is filled with both starch and the enzyme α-amylase. This

Cell Energy Worksheet Answer the following questions: Cellular respiration: • What is cellular respiration and what are its three stages? The main function of cellular respiration is to generate ATP for cellular work; it is the process of harvesting chemical energy from organic fuel and converting it to ATP energy. The three stages of cell respiration include: Glycolysis‚ Citric Acid Cycle‚ and Electron Transport(Simon‚ Reece‚ & Dickery‚ 2010). • What is the role of glycolysis

Red blood cell From Wikipedia‚ the free encyclopedia [pic] Human red blood cells (6-8μm) Red blood cells (also referred to as erythrocytes) are the most common type of blood cell and the vertebrateorganism’s principal means of delivering oxygen (O2) to the body tissues via the blood flow through thecirculatory system. They take up oxygen in the lungs or gills and release it while squeezing through the body’scapillaries. These cells’ cytoplasm is rich in hemoglobin‚ an iron-containing biomolecule that

Physics 1003 Experiment Report In this experiment‚ the technician began with the demonstration of solar energy. Solar energy is the conversion of light energy to electrical energy by using solar panels. Solar panels are devices that contained solar module which use light energy from light to generate electricity through the photovoltaic effect. And photovoltaic modules generate electricity from a frequency of light. From my observation of the experiment‚ I found that the panel is black in

Plant cells are eukaryotic cells that differ in several key aspects from the cells of other eukaryotic organisms. Their distinctive features include: A large central vacuole‚ a water-filled volume enclosed by a membrane known as the tonoplast maintains the cell’s turgor‚ controls movement of molecules between the cytosol and sap‚ stores useful material and digests waste proteins and organelles. A cell wall composed of cellulose and hemicellulose‚ pectin and in many cases lignin‚ is secreted by
