Makalah Biologi Percobaan Reaksi Hidrogen Peroksida dengan Katalase Penulis: Jancolin Yani Pendahuluan Seperti yang kita tahu bahwa hydrogen peroksida yang dihasilkan oleh sel-sel didalam tubuh kita akibat metabolism sel akan terpecah menjadi gas hydrogen dan oksigen dengan adanya keberadaan enzim katalase. Zat hydrogen peroksida sangat berbahaya bagi tubuh dalam kuantitas yang banyak oleh karena itu harus dipecah dan dikeluarkan. Sebagian besar zat hydrogen peroksida

Prediction I think that the speed of the cart will decrease as more weight is added on top of the cart. This is because the more weight that is placed on the moving vehicle/object‚ the more downward force is produced. This would increase the friction between the wheels of the cart and the ramp’s surface. The increase in friction would slow down the moving object (cart). Apparatus Trolley/cart- this is essentially a wooden block with wheels and a rubber end‚ to provide the collision with a

constant speed AC motor‚ while the HP stage is driven by a variable speed DC motor. This feature allows variation of the intermediate pressure. Each stage is provided with its own dynamometer. At compressor’s inlet there is an airbox with a sharp-edged orifice for flow measurement. An intercooler is provided between the two stages‚ and an intercooler between the second stage and the pressure vessel. Connected to the pressure vessel is an exhaust pipe with a throttling valve and a calibrated flow

The Perspiration Workout Unit of the ‘Passive Anaerobic and Aerobic Exercise Assist System for the Inactive and Sedentary Population’ is essentially an infrared dry sauna‚ the heaters produce infrared rays that superficially heat skin and other exposed surfaces but not the air.[7]‚ which is absorbed by the surface of the skin.[1] A study of patients with rheumatoid arthritis and ankylosing spondylitis showed a reduction in pain‚ stiffness and fatigue during infrared sauna therapy.

Research question : How does the different light intensity affect the rate of photosynthesis in plants? Objective : To investigate the relationship between different light intensity (by having the source of light at different distance to the plant discs which is at; 10cm‚ 15cm‚ 20cm‚ 25cm‚ 30cm‚ and 35cm ) and rate of photosynthesis of plant. Introduction : Photosynthesis is the process where light energy is absorbed by green plants to convert the raw materials (carbon dioxide and water) into

The Effect of Solvent Exposure and Temperature on Beet Cell Membrane Integrity Introduction: • Cell membranes are vital to proper cellular function • Cell membranes consist of a lipid bilayer made up of phospholipids • Phospholipids are amphipathic molecules meaning they have a dual nature in that they show both hydrophilic (water-loving) and hydrophobic (water-fearing) properties • The amphipathic nature of phospholipids causes them to spontaneously form bilayers in water
