Cells obtain raw materials and energy primarily from their environment through processes like cellular respiration and photosynthesis. In multicellular organisms, nutrients such as glucose and oxygen are transported via the bloodstream, while in plants, sunlight, carbon dioxide, and water are absorbed for energy production. These raw materials are then utilized in metabolic pathways to generate ATP, the energy currency of the cell, enabling various cellular functions.
The energy used in living organisms to change materials into new forms and move needed material from one place to another is typically chemical energy. This energy is released through various metabolic processes such as cellular respiration and photosynthesis, allowing organisms to carry out essential functions for survival and growth.
Body organs perform various functions that support energy storage, primarily through adipose tissue (fat) and the liver. Adipose tissue stores energy in the form of triglycerides, providing insulation and cushioning for organs. The liver plays a critical role in regulating energy metabolism by converting excess glucose into glycogen for short-term storage and releasing it as needed. Together, these organs help maintain energy balance and supply fuel for bodily functions.

Energy needed for metabolism does not come from vitamins. Vitamins are essential nutrients that support various bodily functions and processes, but they do not provide energy directly. Energy for metabolism usually comes from macronutrients such as carbohydrates, fats, and proteins.
Energy obtained from food is used within an organism to carry out essential functions such as metabolism, growth, reproduction, and movement. It is stored in the form of ATP (adenosine triphosphate) and utilized by cells to perform work and maintain life processes. Energy is also needed for maintaining body temperature, nerve function, and overall cellular activity.
Chemical energy, which we later convert to the various forms of energy needed to perform the functions of our daily lives.
ATP (adenosine triphosphate) as an energy transfer molecule.
Energy is needed by the body to perform essential functions such as metabolism, growth, repair of tissues, and physical activity. It is obtained through the breakdown of carbohydrates, fats, and proteins that are consumed in the diet. Energy also helps in supporting the body's overall health and well-being.
Cell energy is needed in order to perform essential cellular functions such as growth, repair, and maintenance. This energy is generated through processes like cellular respiration, which converts nutrients into adenosine triphosphate (ATP) that provides the necessary energy for cellular activities. Without sufficient cell energy, cells would be unable to carry out their functions and would ultimately die.
When a cell needs energy, it breaks down ATP molecules into ADP and inorganic phosphate, releasing energy in the process. This energy is used by the cell to perform various functions like muscle contraction or protein synthesis.
