carbohydrates !
Calories from food are broken down into nutrients like glucose, which is then used as a primary energy source for cells through cellular respiration in the mitochondria. Cytosine is a nitrogenous base in DNA and RNA, not a direct source of energy for cells.
No. That's false.
Cells use carbohydrates as a source of energy and for energy storage.

emm we use food
They use food that your body has consumed.
Cells use glucose as their primary source of energy. Glucose is a type of sugar that is obtained from the food we eat, and it is transported through the bloodstream to cells where it is used in the production of energy through a process called cellular respiration.
Mitochondria. Muscle cells need more energy over a short period of exercise than most other cells. The cell uses mitochondria to transform food energy into a energy source it can use for its reactions.
The fuel source that gives energy to all the activities of cells in organisms on earth is adenosine triphosphate (ATP). ATP is produced through processes like cellular respiration, which convert nutrients from food into ATP molecules that cells can use for energy.
