Question

Two students set up the following apparatus in a lab: a pipette was filled with a mixture of yeast and apple juice and inverted in a test tube filled with warm water. The students observed bubbles being released from the end of the pipette. Which MOST LIKELY represents the gas being released and the process used to make it?

Answer 1

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.

Answer 2

The gas being released is carbon dioxide and in the process called cellular respiration.

In apparatus set up by the students, the yeast used the sugar in the apple juice together with the oxygen to generate adenosine triphosphate (ATP) and releases carbon dioxide as a waste.

Further Explanation

Yeast is a one-celled organism that requires energy to survive. Yeast can do anaerobic and aerobic respiration. For yeast to survive, it has to make its energy.

To survive, yeast uses cellular respiration, where glucose is transformed into ATP and carbon dioxide.

In other words, cellular respiration is a metabolic process that involves the breaking down of glucose to generate adenosine triphosphate (ATP) and releases waste products. The waste product is carbon dioxide (C02)

Cellular respiration is used by both plants and animals to break down sugar and convert it into energy. The energy produced is used by plants and animals to carry out some task at the cellular level. The essence of cellular respiration is to provide the energy required for cells to function.

Therefore, in the apparatus set up by the students, the yeast used the sugar in the apple juice together with the oxygen to produce adenosine triphosphate (ATP) and discharges carbon dioxide as a by-product.
