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.
