In the yeast fermentation experiment, the gas bubble got larger. what gas was causing this increase in bubble size?

The gas produced is carbon dioxide.

Yeasts fermentatewhich is a metabolic process that consumes glucose in the absence of oxygen.

This results in the production of ethanol and carbon dioxide which can be used in food processing. The ethanol is used to make alcoholic beverages andd carbon dioxide it's what makes bread rise  (those bubbles/holes in the bread were space ocupied by CO2)

Cis your correct answer

Mitochondria is the cell organelle that produced the energy that is needed in the body system in form of atp, that is why it is called the power house of the cell. energy is needed by the living organisms to carry out the activities which sustain life.  if the mitochondria is destroyed atp will not be produced. if the mitochondria is destroyed, energy production will stop and the affected living organism will not have the energy to carry out the necessary life processes; this will lead to the death of the organism.
