Review
Gibbs free energy in chemical reaction
The free energy of a living human is in 1 general much larger than that of a general much larger than that of a dead body. Explain why. Suppose that the human absorbs Suppose that the human absorbs energy from the Earth. Show that its free energy cannot increase in this free energy cannot increase in this process.

In order to live, a human must eat some 2 food. Show that the human can increase her/his free energy by reducing the free energy of food, in the process of absorbing energy from the food.
Digestion of the Glucose
F Free energy acquisition i iti during the digestion of glucose
Carbohydrate : 400g/day Protein : 100g/day Protein : 100g/day Fat : 50g/day ΔG=3076.65KJ/day
Accordingly, what is needed is the food 3 with large free energy, the origin of which is the photo-synthesis of plants. Estimate the maximum possible increase of the free energy of a plant in a day, as it absorbs energy from the sun.
