BIOCHEMICAL REACTIONS AND ENZYMES I. Structure supports function. Function is physiology and metabolism. Metabolism is the sum of the biochemical reactions inside a cell. Lets take a closer look at how biochemical reactions or just ordinary chemical reactions occur. A. Collision theory: This makes sense as an explanation of how two molecules may interact to form bonds. One bangs into another. If the collision is energetic enough-- we see this as the reaction mixture being hot enough---or as Activation Energy---and if the vulnerable parts of the molecules are the ones that get hit, we get bonds breaking and new bonds forming.

Unformatted text preview: -----> IO-+ H 2 O IO-+ H 2 O 2----> O 2 + H 2 O + I-Two points should be made about the above reaction. It takes two steps to happen. I-is not used up in the reaction. The reaction occurs due to contact with I-where bonds are broken and new bonds formed. What bond is broken and what new bond forms? Also, I-is an inorganic small ion. Small inorganic species that speed reactions are called catalysts. Define: Activiation Energy, catalyst (two examples), exergonic reaction, endergonic reaction. Show hydrogen peroxide and Iodide catalyst and catalase reaction. Explain how catalase identifies organisms Staph and Strep....
