Cellular respiration is the process by which cells break down glucose (or other molecules) in the presence of oxygen to produce energy in the form of ATP.

For A: While photosynthesis is a process that converts sunlight into chemical energy in the form of glucose, it does not produce ATP as its primary outcome. However, ATP is used during the light-dependent reactions of photosynthesis to help convert sunlight into glucose.
For C: Transcription is the process ...
