Ch 3 - Energy, catalysis, and biosynthesis

Describe the general flow of energy in the biological system/cell

Describe the 1st and 2nd laws of thermodynamics and why live cells don’t defy the 2nd law

define ΔG, ΔG°, and Keq, and know the relationship between the terms.

Know the equations to calculate each of them (ΔG, ΔG°, and Keq) given reaction and the concentration of reactants and products

Predict whether a reaction will occur spontaneously based on the values of ΔG. Be able to calculate net ΔG for coupled reactions.

Explain why enzymes are used in biological systems. How do they increase the rate of a reaction? Do they change the equilibrium of a reaction?

Explain catabolic and anabolic reactions

Describe oxidation and reduction

Describe reactions and their importance in the cell

relate the concept of free energy with catabolic and anabolic reactions

describe activated carriers and their role in biosynthesis

Describe condensation reaction and bioenergetic aspects of polymerization of sugars, amino acids, and nucleotides
