Chapter 8, Problem 11TYU
Summary Introduction
To explain: The kinetic and potential energy in the penguins jump that are jumping into water, the energy conversions when the penguins climb back on the glacier after eating fishes, and the role of enzymes and ATP in the
Introduction: The penguins jump from the glacier into the ocean to catch fish. The potential energy conserved in their body, due to the height of the glacier is converted into the kinetic energy of motion. This is according to the law of conservation of energy.

Relating to bioenergetics:
a. The equilibrium constant for a particular reaction is 6.8 x 10-5 which makes this reaction exergonic. True or False?b. All processes that occur in the universe are spontaneous and have low enough activation energies that molecules can often overcome the energy barrier. True or False?c. ATP has a highly negative free energy change in part because the negative charges on the oxygens repel each other in ATP but less so in ADP. True or False?
Classify each of the following examples as: (1) potential energy, (2) kinetic
