A procaryotic cell has five essential structural components: a nucleoid (DNA), ribosomes, cell membrane, cell wall, and some sort of surface layer, which may or may not be an inherent part of the wall.
In terms of chemistry, saturated fats contain the maximum number or greatest amount of Hydrogen atoms covalently bonded to both the end and internal or middle carbons. Thus, there are no carbon to carbon double and or single bonds present.
Unsaturated fats though do have at least a minimum of 1 carbon to carbon double and or triple bond for the inverse or opposite explanation of what was mentioned, that it does not have the maximum number of hydrogen atoms within the internal and or external carbon atoms in the structure of the organic compound.

Carbon dioxide because people in other animals exhale carbon dioxide as a waste product. People and other animals need oxygen for plants produce oxygen during an important process called photosynthesis which turns the sun energy into nutrients so carbon dioxide would be the answer.
