BIOCHEM 2280-MIDTERM EXAM QUESTIONS AND ANSWERS LATEST 2025/2026 UPDATE 100% ACCURATE what is biochemistry? --this is the chemistry of living things, so how life works at a molecule and chemical level -interested in structures and function of the molecules involved what are the major classes of biomolecules, and what can they form a polymer of --there are amino acids, which polymerize to form proteins -there are nucleotides, which polymerize to form nucleic acid -there are carbohydrates, which polymerize to form polysaccharides - and there are lipids, which do not polyermize but they can self associated into a defined structure what is the change in free energy determined by -this is determined by change in enthalpy (H) - T x change in entropy (s) -when G is negative, the reaction is spontaneous, or exergonic, so energy is released
