There are approximately 40‚000 enzymes living in one human cell‚ each responsible for a chemical reaction. Enzymes are complex 3D protein molecules created by amino acids‚ forming a unique sequence that produces hydrogen bonds‚ eventually formulating an enzyme within plants and animals (Boyle & Senior‚ 2002). Working alongside other molecules‚ they uphold a stable reaction system. The function of an enzyme is to aid and increase chemical reactions and organise metabolism‚ while maintaining homeostasis

the temperature the faster the reaction will occur) has been proven correct and it proves the theory right. From the results‚ we can see this‚ as the iced water (10 degrees) had the slowest rate of reaction at 1.10 minutes. Then the room temperature water (19 degrees) was tested and had a slightly better rate of reaction at 1.09 minutes. Then last of all‚ we tested the boiling water (63 degrees) which had a large improvement from the last two with a rate of reaction of 43.5 seconds. This showing development

Hurricanes have made a huge impact on the world. They have impacted our environments and society. We have discovered what hurricanes do and how they occur‚ and what they are. There are 5 different categories of hurricane 5 being the worst and 1 being the least strongest. People have reacted differently to different hurricanes. One recent hurricane known as Hurricane harvey was a very deadly and one of the most destructive hurricanes in history. It ruined lives‚ homes‚ and buildings.

How do shapes affect structure? From the Roman arches to the triangular Great pyramids to religious domes and the variety of quadrilaterals found on steel-frame buildings of the 20th century‚ architecture is largely predicated on shapes. The mathematical attributes of shapes are necessary to the design of any standing structure. Arch The Romans first used arches around 273 B.C. Arches served as entrances for large‚ outdoor public spaces. Today‚ arches are found on porches‚ doorways and

However‚ organs such as the brain‚ liver and kidney do not just rely on carbohydrates to receive their energy. A process known as gluconeogenesis takes place in these organs when the body goes into a fasting period‚ intensive exercise or when there is a low-carbohydrate intake. The process of gluconeogenesis

Investigation Aim: The aim of the investigation was to investigate the effect of substrate concentration Hydrogen Peroxide H O (in %) on the rate of reaction of the enzyme catalase (in 1/mean time). Prediction: As the substrate concentration (hydrogen peroxide) in % increases the rate of reaction in 1/mean rate increases until the solution becomes saturated with the substrate hydrogen peroxide. When this saturation point is reached‚ then adding extra substrate will make no difference. The

Human Impacts on island ecosystems. (Australia) There are few paleovegetation records in Australia before 18‚000 years ago. To find out the history of the Australian fauna scientists used stable carbon isotopes from the emu eggshell (a flightless bird native to Australia). The samples were largely taken from Lake Eyre. The carbon composition of the eggshell tells us the composition of the bird’s diet (over 3-5 days). The emus are mixed feeders herbivores‚ eating leaves‚ shoots‚ fruits‚ flowers
