In assessing metabolic processes, we are usually more interested in the work that may be performed for the consumption of a given mass of compound than the heat it can produce (which merely keeps the body warm). recall from chapter 2 that the change in gibbs energy can be identifi ed with the maximum nonexpansion work that can be extracted from a process. what is the maximum energy that can be extracted as (i) heat and (ii) nonexpansion work when 1.0 kg of sucrose is burned under standard conditions at 298 k?
