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)

heart is abnormal. “An ECG records the electrical activity of the heart. The heart produces tiny electrical impulses which spread through the heart muscle to make the heart contract” (Kenny‚ 2015). There are two different types of cells. Autorhythmic (electrical) cell begins electrical activity and triggers contractile fiber‚ and contractile (myocardial) generates force to

experiment my supervisor Ms. Ehnar Jiy conducted. In this lab‚ i wanted to know if more active cells in our bodies require more energy. I started of by taking five samples of three different types of cell (skin cell‚ muscle cell and lung cell) and counted the mitochondria present in each by viewing the cells under a powerful optical microscope. According to my data‚ i found out that my hypothesis was accurate‚ i predicted that more active cells in our bodies require more energy then there will be a

Kramas Cells and Heredity Lab Tuesday 2:00-4:50 22 OCTOBER 2012 Membrane Permeability Decreases as Molecular Size Increases Introduction: Red blood cells are vital to organisms functioning properly. They are microscopic cells that carry oxygen from the lungs to all the tissues throughout the body. Upon transporting oxygen‚ red blood cells also exports waste‚ such as carbon dioxide‚ to the lungs where it can be expelled. Red blood cells are made up of hemoglobin which is surrounded by a cell membrane

I. Introduction: The purpose of this lab report is to differentiate between of Newton’s Third Law and Newton’s Second Law. Newton’s Third Law states that all forces come in pairs and that the two forces in a pair act on different objects and are equal in strength and opposite in direction. Newton’s Second Law states that the acceleration of an object is proportional to the net force and inversely proportional to the mass of the object being accelerated. Using calculation equations for acceleration

sun-sensitive people‚ reducing the risk of breast cancer and other diseases‚ preventing asthma attacks caused by exercise‚ as well as many other uses. Chlorophyll is the green‚ light-capturing pigment found in plants. Chlorophyll (like heme in red blood cells) is an example of porphyrin. In this experiment‚ chlorophyll and ß-carotene were isolated using the technique of column chromatography. Column chromatography is a method used to separate and purify components in a mixture. In gravity column chromatography

plant and animal cells are placed in a hypotonic environment‚ osmosis will occur. The structure of these cells determines the response to the difference in gradient‚ whether this be lysis (the explosion of cells due to the sudden increase in water pressure within the cell) in animal cells or turgor pressure (the pressure created by the increase in water pressure within the cell) in plant cells. Turgor pressure prevents further osmosis‚ which causes the water potential outside the cell to be lower than

Lab 2: Animal and Plant Cells Purpose: To examine the differences between single cell and multi cell organisms in terms of Animal and Plant cells. Question: What are the differences between multi and single celled plant and animal organisms? Prediction: Spirogyra Cell: The parts of the spirogyra cell that will be visible under the microscope will be; cell wall‚ cell membrane‚ nucleus‚ chloroplasts‚ vacuole and cytoplasm. Banana Cell: The parts of the banana cell that will be visible
