Study questions 7 and midterm preview 1. The synthesis of DNA from nucleotide monomers requires the use of considerable energy. En- ergy is required for two reasons. The Frst is to make the bonds of the phosphodiester-sugar chain (this is the O-P-O-C-R-O-P-O-C-R-O chain). The second is because the polymerized DNA is more ordered than the monomer nucleotides 2. A plant cell is immersed in a solution that is 0.05M glucose. The intracellular concentration of glucose is 0.01M. The glucose in solution can be acquired by the cell through the process of DIFFUSION 3. The process requires the presence in the membrane of A CHANNEL and the use of this ap- proximate amount of energy NONE 4. Consider the situation in question 2. If the solution molarity of glucose is 0.001, and the intra- cellular concentration remains the same, the glucose in solution can be acquired by the cell through the process of _ACTIVE TRANSPORT_. 5. The process requires the presence in the membrane of A TRANSPORTED and the use of this approximate amount of energy MODERATE TO HIGH, DEPENDING ON CONDITIONS 6. G° represents the change in free energy from reagents to products under the following type of conditions: STANDARDS, 1 MOLE OF EACH MOLECULE 7. G represents the change in free energy from reagents to products under the following type of conditions: ANY SPECIFIC CONDITION 8. You can predict wether a given concentration of products and reagents of a chemical reaction will produce a given conversion (A: products --> reagents) or (B: reagents --> products) by the value of G. If the value is NEGATIVE the reaction will go in the direction shown in A,
