The change in free energy between reactants and products can be used to determine if a reaction is spontaneous. in terms of the similarities in their bioenergetic needs. a. What is meant by the free energy terms AG 2. How does the second law of thermodynamics apply to energy conversion systems in a living organism? and AG?Explanation / Answer
Ans-1 during night there is no photo synthesis in plants so they don't take carbon die oxide to make their food. During this period they make use of oxygen and release co2 as other animals so it is said here that plants energic needs become similar to animals during night.
Ans-2 it states that two bodies in contact with each other with different temperature tends to even out and lead to work.for e.g. the plant make food with the help of photosynthesis in sunlight. Here they get heat from sun and make use of light to make usable food which produce energy for plant to survive.
Ans-3(a)- g is Gibbs free energy change at any temperature and pressure while g° means free energy change at standard temperature and pressure (I.e. 25k and 1 atm)
Ans-3(b)- at equilibrium the equation is G= G°RT ln Q
Ans-3-(c)- the enzymes will speed up the reaction and the reaction will reach at equilibrium state rapidly as compare to absence of enzyme
