Homework Answers
1) Potential Energy is the stored energy which can be used in future.
Examples:- Carbohydrates, Fats, Proteins, ATP, Phosphocreatine(PCr)
Kinetic Energy is the energy that is generated in human body when it is in motion.
Examples :- Heat, Muscle Contraction( Mechanical work), Chemical work.
Example of each type of work in human body are as follow:-
Mechanical work :- Beating of cilia, Muscle contraction.
Chemical work :- Converting polymers to monomers leading a cell to create many molecules.
Transport work :- Pumping of the substances across the membrane like sending ions across the plasma membrane . In this example sending substances such as protein around the cell is a form of transport work.
2) Match the following terms with definition:-
Metabolism :- (B) is the amount of energy available to do work after a chemical reaction has occurred ( breakdown of micronutrients)
Free energy :- (D) is the sum of all chemical activities occuring inside a cell.
Anaerobic :- (C) energy reactions that generate energy rapidly from chemical reaction without the requirement of oxygen.
Aerobic :- (A) Oxygen requiring energy reactions.
Thermodynamics : - (E) the study of energy relationships and exchanges.

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
