4.9 Summary. Energy is the ability to do work. It is needed by all living things and every living cell to carry out life processes, such as breaking down and building up molecules, and transporting many molecules across cell membranes. The form of energy that living things need for these processes is chemical energy, and it comes from food.

Energy and Metabolism. All living organisms need energy to grow and reproduce, maintain their structures, and respond to their environments. Metabolism is the set of life-sustaining chemical processes that enables organisms transform the chemical energy stored in molecules into energy that can be used for cellular processes.
Apr 25, 2017 · Importance Of Energy To Living Things . Living things are made up of millions of cells which perform various functions in the body such as repair, growth, and movement. All chemical processes taking place in cells are summed up as metabolism. If metabolism stops, the living thing subsequently dies. Energy is, therefore, critical to the ...
Figure 9.1.1 9.1. 1: The structure of ATP shows the basic components of a two-ring adenine, five-carbon ribose sugar, and three phosphate groups. A large amount of energy is required in order to recharge a molecule of ADP into ATP. This energy is stored in the bond between the second and third phosphates. When this bond is broken, the energy is ...

Energy in Living Systems. All living organisms require energy to perform their life processes. Energy, as you learned earlier in the chapter about enzymes, is the ability to do work or to create some kind of change. You are familiar with or have learned about many processes that can require energy: Movement. Reproduction.
