(a)
(b) Bioenergetics
(c) Enthalpy
(d) Entropy
(e) Free energy
Introduction:
Energy is the quantitative property defined as capacity to do work serve as an essential element of life. The relationship between matter and energy was defined by the Einstein’s equation. It revealed that the energy and the matter are interconvertible and that the matter is condensed energy.

Question 4.3
Now it's your turn to design and experiment. Your Aunt Kayla and Uncle Jerome, want to be home-brewers. When they
find out that you have been studying yeast metabolism and the scientific method, they request your help in the study-
design portion. Uncle Jerome likes beer that is very carbonated; whereas Aunt Kayla likes beer that is only mildly
carbonated. They each want to make their own batch of beer. Using the information learned from this data, write
instructions for each person in terms of which carbohydrate source to use and how long to allow the incubation to occur.
