ATP? im not sure though
carbohydrates, glucose
sunlight
reduced
Sugar
Glucose is the preferred energy source.
adenoidine triphosphate a molcule that acts as the main energy source for cell processes

The molecule that is the primary source of energy in all cells is ATP, which is definitely not a macromolecule. The molecule that is the primary source of energy in cells for making ATP from ADP is glucose, which is definitely not a macromolecule. Macromolecules that can be metabolized for energy (starches, fatty acids, proteins) are only secondary or tertiary sources of energy as the process of extracting energy from them is slow and inefficient.
Mitochondria (singular, mitochondrion) are organelles that carry out cellular respiration in nearly all eukaryotic cells, converting the chemical energy of foods such as sugars to the chemical energy of a molecule called ATP (adenosine triphosphate). ATP is the main energy source for cellular work.
The preferred source of energy for the heart muscle is fatty acids. Fatty acids are "good fats" that are main sources of energy for cells.
The main energy source used in cellular respiration, particularly in animals, is glucose. It is the common energy source cells use in respiration to generate ATP.
In its form, glucose is ready for absorption into the blood stream. As such, it is the most preferred source of energy in body cells.
No that would be glucose, if lipids were the preferred source then fat burning would be very simple, lipids are long term energy stores.
