The main source of energy for cellular creatures is ATP (adenosine triphosphate); this is produced by glucose (simple sugar). Carbohydrates usually break down into sugars. So carbohydrates are an indirect source of energy.
carbohydrates
The main source of energy for all living things is carbohydrates. They are broken down into glucose during digestion and then used in cellular respiration to produce ATP, which is the primary energy carrier in cells.
carbohydrates
Carbohydrates provide the main source of energy for the body, particularly for the brain and muscles. They are broken down into glucose, which is used by the body for fuel and to support various physiological functions.
energy
glucose is the source of energy for all living things.
If you eat too many carbohydrates and don't exercise enough you will put on weight. Wheat products are a good source of carbohydrates. Carbohydrates are the most common source of energy in living things. If you do not want to eat carbohydrates, then avoid potato chips.
They are a source of energy for most living things but they are also used for building blocks to modify proteins. Plants use carbohydrates in the form of cellulose to build their rigid structures.
AnswerProtein, nucleic acids, carbohydrates, and lipids
The main source of energy for living things is the body's process for breaking down food. For plants, the main source of energy is the sun, which, when combined with water and carbon dioxide, creates plant matter.
All living things require a source of energy.
Carbohydrates, such as glucose, are the main source of energy for cells. Glucose is broken down through a series of biochemical reactions in a process called cellular respiration to produce ATP, the cell's primary energy currency.
