the activity of the enzyme catalase? Hypothesis: By increasing the concentration of FeSO4‚ there will be a decrease in the activity of the enzyme catalase because the Iron (ii) in the metallic ion will act as an inhibitor during the catalysis of the hydrogen peroxide into O2 and H2O. Introduction: We rely on oxygen to provide us with energy (ATP) and go through all the phases of aerobic respiration. However‚ oxygen can be harmful to humans and can cause problems if not carefully regulated. Our

Plant Cell Plant cells have many different parts that are need to work together and function as a whole. These parts are the cell membrane which can be compared to a "Condom" due to the fact that is a very thin protective layer that lets certain substances to pass through. Cell wall is a thicker rougher membrane‚ which gives the plant most of its structure and support‚ the cell wall also bond with other cell walls to form the structure of the plant. Centrosome may be also referred to as the

Effect of Temperature on Enzymes ~Abstract~ In this experiment the effect of different types of temperatures on enzyme activity was examined. The temperature baths that were used to test the difference in enzyme activity on fresh liver were; 4 °C‚ room temperature which was 22°C‚ body temperature which is 37°C‚ and 77°C. The total time of each trial was 2 and a half minute‚ 1 minute for the H2O2 to acclimatize to the temperature‚ 1 and a half minutes for the reaction to occur. Catalase causes Hydrogen

Enzyme Lab Using Jello INTRODUCTION: Enzymes are known as protein catalysts. The name protein catalyst suggests that most enzymes are made of proteins. A catalyst is a substance that speeds up chemical reactions without being consumed in the process. (Giuseppe‚ M 2002‚ p.69). After a reaction has been catalyzed‚ the catalyst can be used again to catalyze the same reaction. Enzymes reduce the activation energy (minimal energy) it takes for a reaction to take place. Enzymes can either catabolize

Cell Transformation Cell transformation is when a cell takes in DNA from the outside of the cell. It then becomes a component of the cell’s DNA. There are three different ways in transforming the cells. There is transforming bacteria‚ transforming plant cells‚ and transforming animal cells. The purpose of cell transformation is to introduce a foreign plasmid in order to make large quantities of it. In transforming bacteria‚ a foreign DNA is first joined to a small circular DNA molecule known

An experiment was run to determine which enzyme (pectinase‚ and cellulase or combinations of the two enzymes) maximizes juice production and would be most cost effective. The proposed hypothesis was if the enzyme‚ pectinase‚ is added to apple juice‚ then the more juice will be extracted than if cellulase were added because pectinase holds the cell wall together and if it is separated apart from each other‚ then the more juice would be able to flow out. The experimental data show that during the ten

Prokaryotic Cell Structure Bacterial Cell Structure Mariana Ruiz Villarreal/Wikimedia Commons Prokaryotes are single-celled organisms that are the earliest and most primitive forms of life on earth. As organized in the Three Domain System‚ prokaryotes include bacteria and archaeans. Prokaryotes are able to live and thrive in various types of environments including extreme habitats such as hydrothermal vents‚ hot springs‚ swamps‚ wetlands‚ and the guts of animals.

Premium Bacteria DNA Eukaryote
Eukaryotes are organisms whose cells are organized into complex structures by internal membranes and a cytoskeleton. The most characteristic membrane bound structure is the nucleus. This feature gives them their name‚ (also spelled "eucaryote‚") which comes from the Greek word referring to the nucleus. Animals‚ plants‚ fungi‚ and protists are eukaryotes. Microorganisms and all other living organisms are classified as prokaryotes or eukaryotes. Prokaryotes and eukaryotes are distinguished on the

Lab Ex#8: "Enzymes: Catalysts of Life" INTRODUCTION Enzymes are protein organelles where chemical reactions take place to generate energy within our cells. Without the energy produced from the cell enzyme activity‚ we would not possess the catalyst activity necessary for energy to produce movement. Each enzyme performs a specific function within our bodies. Those functions performed can be significantly altered with the introduction of variables outside their environment. Variables‚ such as temperature

DESCRIBE THE STRUCTURAL COMPARTMENTATION OF MAMMALIAN CELLS AND THE DIFFERING FUNCTIONS OF THESE COMPARTMENTS? Mammalian cells are eukaryotic this means that all of their cells have common components‚ membrane bound organelles which prokaryotic cells do not this is shown in figure 1. Organelles are purpose made to carry out a specific function that is necessary within a cell. Due to the specificity of both conditions and concentrations with in these organelles these are compartmentalized. Encasing
