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.

Oct 31, 2023 · Like a generating plant, living organisms must take in energy from their environment and convert it into to a form their cells can use. Organisms ingest large molecules, like carbohydrates, proteins, and fats, and convert them into smaller molecules like carbon dioxide and water.

What processes require energy?
Discuss the importance of electrons in the transfer of energy in living systems. Explain how ATP is used by cells as an energy source. Energy conversion within a cell involves many coordinated chemical pathways. Most of these pathways are combinations of oxidation and reduction reactions, which occur at the same time.
Oct 19, 2023 · There are a number of different ways energy can be changed, such as when potential energy becomes kinetic energy or when one object moves another object. Energy cannot be created or destroyed, but it can be transferred and transformed.

Gas stoves transform chemical energy from natural gas into heat energy. Plants perform one of the most biologically useful energy transformations on earth: that of converting the energy of sunlight to chemical energy stored within organic molecules ( Figure 4.2 ).
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; Maintaining homeostasis of many different conditions
