Part A - Overview of enzyme structure and enzymatic reactions Enzymes are large globular proteins. Much of their three dimensional shape is the result of interactions between the R (variable) groups of their amino acids. The active site is the portion of the enzyme that will interact with the substrate the molecule that the enzyme acts upon. The nature and arrangement of amino acids in the active site make each enzyme specific to a substrate and to the reaction it...

Question 1 4 pts CoH1206 + 602 ---> 6CO2 + 6H2O + Energy In the overall equation for cellular respiration above, it is clear that this reaction is A because energy is a product of this reaction which results in a B_AG. This suggests that this reaction will be c_within a biological system which means that it can occur on its own. In addition to...

Justify the following sentences by answering (T) for TRUE or (F) for FALSE. (1 mark each) AE is independent on the initial and final state of a system. The sum of entropy changes of the system and surroundings is always positive. The ratio of numerical values of partial pressures of the reaction participants is unitless. Q is small if products pressures are small, a large Q means a negative or good (favorable) contribution to the free energy For pure solids...
