Background Information In stars the nuclei of Hydrogen and Helium is fused into heavier elements. It is also believed that the relative high abundance of Hydrogen Helium and Lithium is because they were all created during the Big Bang by something known as Big Bang Nucleosynthesis. Nucleosynthesis Elements heavier than Lithium are all synthesised in a star (Wollack, 2010) that means that the first three elements of the periodic table (Hydrogen, Helium and Lithium) were all synthesised before the stars...

Rationale There are chemical reactions occurring all around us and without them, even humans would not be able to live. Chemical reactions have major factors that affect the rate of the reaction; temperature is one of those major factors. For example, bread dough rises more quickly in a warm place instead of a cool one, and warm-blooded animals regulate their body temperature so it is optimal for biomechanical reactions to run. A reaction only occurs when the molecules reacting have...

RATIONALE Enzymes are proteins that act as catalysts within living cells. Catalysts increase the rate at which chemical reactions occur without being consumed or permanently altered themselves by lowering their activation energy (Christensen, 2018). Every enzyme has a region called active site, where enzymes are binds to a substrate to create another enzyme and carries a reaction. Enzyme is important because it’s a metabolic pathway in the body like respiration, building muscle, destroying toxins, and breaking down food particles during...
