Energy & Enzymes - Post Assignment a) What is the equation for Gibb's free energy? G = H - (TS) b) Describe each component of this equation and how the equation works overall. Because of the way the free energy of the system is defined Go is negative for any reaction for which Ho is negative and So is positive. Go is therefore negative for any reaction that is favored by both the enthalpy and entropy terms. We can therefore conclude that any reaction for which Go is negative should be favorable or spontaneous. Conversely Go is positive for any reaction for which Ho is positive and So is negative. Any reaction for which Go is positive is therefore unfavorable. a) A common enzyme that you may be familiar with is lactase; people lacking carbon monoxide into carbon dioxide. Another oxidation reaction turns unburned hydrocarbons in the exhaust into carbon dioxide and water. a) What is the difference between the Lock and Key and the Induced Fit hypothesis? Lock and Key states that there is no change needed and that only a certain type will fit. However induced fit says the active site will change to help to substrate fit. In lock and key the active site has one single entry however in induced fit the active site is made of two components b) Draw a diagram describing the Lock and Key hypothesis. c) Draw a diagram describing the Induced Fit hypothesis.
