ppp 26. Why aren't strong bonds as useful for work in the cell? 27. Define chemical equilibrium with regards to reaction concentrations and how a reaction will proceed in the cell (i.e. if starting from 1 M of reactants/products with a Kg of 100). ON

e. 12.. Name both of the molecules below, and circle/ identify which of the following two molecules has lower free energy. I 0- O O O O -P-O O™ N H₂N OH OH no fofo HO- O- OH OH NH₂ N S N OH OH

25. Describe the processes by which the organic molecules are assembled and disassembled. Use (and define) the following terms in your answer: monomer, polymer, anabolic, catabolic, dehydration synthesis, and hydrolysis. Be sure to include the general equations for the reactions involved, making reference to the specific part that water plays in each type of reaction.

12. Explain why those biological reactions that have their equilibria shifted towards theproducts have negative values for ΔGo of reactions. Explain how equilibria relates toGibbs free energy.

H1. Estimate the TKN associated with a sample having 50 mg/L of cell tissue and 10 mg/L of ammonia. Assume cell tissue has a molecular composition of C5H7O2N.

1-sketched a graph to show what I think the effect of temperature will be on the rate of reaction (the effect of temperature on enzyme activity)   2-describe in words what you predict the effect of temperature will be on the rate of reaction
