Which of the following is true?

a. Catabolism is degradative, in which organic molecules are converted into smaller, simpler end products with the consumption of energy.

b. Anabolism is degradative, in which organic molecules are converted into smaller, simpler end products with the consumption of energy.

c. Catabolism is degradative, in which organic molecules are converted into smaller, simpler end products with the release of energy.

d. Catabolism is synthetic, in which small simple precursors are built up into organic molecules with the consumption of energy.

e. Anabolism is synthetic, in which small simple precursors are built up into organic molecules with the release of energy.

Which of the following is true?

a. Enthalpy, H, is the heat content of the reacting system. If a reaction consumes heat is it called exothermic, because it is taking heat from its external surroundings.

b. Entropy, S, is a quantitative expression for the order in a system. The universe tends to move away from entropy.

c. Gibbs free energy, G, expresses the amount of energy available to do work. The temperature and pressure are not relevant.

d. Enthalpy, H, is negative when a reaction is exothermic, because the reaction is releasing heat.

e. Gibbs free energy, G, is positive when a reaction is thermodynamically favorable because it takes energy to make reactions proceed.
