Homework Answers
Glucose molecule - Potential energy ( a stored energy includes chemical potential).Glucose represents chemical potential energy( molecules possess arrangement of atoms). In glucose molecule,the carbon hydrogen bonds represents high energy bonds.
Decayed leaf - Potential energy as a form of stored energy.A decayed leaf is a form of organic matter which is decomposed(breakdown of organic matter into stored form).
Running - Conversion of potential energy into kinetic energy when a person runs potential has been used when the system uses kinetic energy to move in a horizontal direction.It concludes Kinetic energy( the energy of moving objects).
Lipid molecules- Potential chemical molecule.Lipid molecules are free energy of complex molecule are used to store energy in cells.
Active transport of sodium - Kinetic energy.It is a method of transport where electrical potential difference has been created by pumping out of ions out of the cell which is used to transport molecules across a membrane.so the potential energy in the hydrogen ions are translatedd into kinetic energy as the ions moves through the channel protein ATP synthase,and that energy used to convert ADP into ATP.
Perspiring -Kinetic energy. A person giving out of sweat through the pores of skin as a result of exercise,or by heat,stress.so the potential energy converted into kinetic energy.
