The main energy source needed for cellular processes, including those involving single-celled organisms, is **c) ATP (adenosine triphosphate)**. ATP is the primary energy carrier in all living organisms and is used in various biological processes.
- **a) Photosynthesis** refers to the process by which plants and some other organisms convert light energy into chemical energy.
- **b) DNA** is the genetic material that carries the instructions for the development and functioning of living organisms but is not directly an energy source.
- **d) Enzyme** refers to proteins that catalyze biochemical reactions but do not serve as an energy source themselves.
Therefore, the correct answer is **c) ATP**.
