Final answer:
Glucose is an example of a molecule that contains carbon, with a molecular formula of C6H12O6, and is vital for energy processes in living organisms.
Step-by-step explanation:
An example of a molecule containing carbon that was discussed in the video is glucose, which is a sugar with the chemical formula C6H12O6. Glucose has a ring of carbon atoms, making it a central molecule in the metabolism of living organisms.
In photosynthesis, glucose is produced by plants and serves as an essential energy source for both plants and animals. This organic molecule is crucial for cellular respiration, where it is used to produce ATP, the energy currency of the cell. Since the reference to glucose is backed by the information on its molecular structure and its role in photosynthesis and energy transfer, it's clear that glucose contains carbon atoms and fulfills the requirements of the question.
