SBI4U-C 1 Lesson Introducing Biochemistry 1 Lesson 1 Biology SBI4U-C Introduction If you think about it‚ living things are made up of chemicals. The cells‚ tissues‚ organs‚ and organ systems that together make up a functioning organism are all the product of interacting chemicals. In order to understand how the organism functions‚ you must also recognize how these chemicals function. The study of the chemicals that are involved in living things is known as biochemistry

reaction one or both of the products is an insoluble ionic compound or otherwise known as a precipitate; or a non-electrolyte; or a gas. In a single replacement reaction there is typically a metal and an ionic compound consisting of a metal cation and a non-meatl anion. Singel replacement ractions occur when the reacting element is more active‚ whihch means it is more likely to lose electrons than the product element. There was two parts to this experiment‚ in Part A we mixed various aqueous solutions

of moles will be 13 moles of oxygen to 1 mole of lead. In the experiment‚ the students will find the empirical formula of a compound containing magnesium and oxygen. Based on prior knowledge‚ the student believes that the ratio of magnesium cations to oxygen anions will be one to one. The student also believes that the ratio of moles of magnesium to moles of oxygen will not be one to one.

Making an Activity Series of Metals using different Solutions Purpose/ Hypothesis: The purpose of this lab was to clearly identify the reactivity of magnesium‚ zinc and copper. The metals reactivity will be exemplified as it will be tested with different solutions such as zinc sulfate (ZnSO4)‚ copper sulfate (CuSO4)‚ hydrochloric acid (HCL)‚ magnesium sulfate (Mg2SO4)‚ iron (II) sulfate (FeSO4) and tin (II) chloride (SnCl2). This will allow us in creating an activity series to visually see the reactivity

titration. The average concentration of CaCO3 obtained was 1034 ppm‚ with a standard deviation of 2.4495. The results indicate that the unknown solution can be considered as hard water. Introduction The hardness of water is defined in terms of its cation content‚ which includes calcium‚ magnesium‚ iron‚ zinc‚ and other polyvalent metal ions. These metal ions interfere with the use of the water for many applications. For example‚ these ions diminish the effectiveness of soap and detergent for cleansing

Targets can be divided into four categories… Ion Channels Their modulation by drugs is very important mechanism by which pharmacological actions are produced . 1. Voltage gated Na2+ channels ( local anesthetic) 2. Calcium channels ( Ca2+ channel blockers) 3. K+ channels ( in pancreatic β-cells) Enzymes * Many enzymes are targets for drugs * Drug molecules can act as competitive inhibitor of the enzyme e.g. neostigmine acting
