Answer:
The most appropriate answer would be carbon dioxide and cellular respiration.
Yeast is a single-celled eukaryotic organism which is capable of doing anaerobic (fermentation) as well as aerobic respiration.
It uses cellular respiration (whether aerobic or anaerobic) for the production of energy, that is, adenosine triphosphate (ATP).
Cellular respiration refers to the set of chemical reactions which are involved in breaking down sugar or glucose to produce ATP. The carbon dioxide is produced as a byproduct.
Thus, yeast breakdown the sugar present in apple juice to produce ATP and carbon dioxide.
This carbon dioxide is released in the form of bubbles.
