Does the concentration of different sugar solutions affect the rate of cellular respiration in yeast?

Definition Definition Set of metabolic processes and reactions that produce energy from organic substances such as glucose. Cellular respiration takes place in the organism’s cells, where the chemical energy from nutrients or molecules of oxygen is converted into adenosine triphosphate (ATP). Cellular respiration that occurs in the presence of oxygen is called aerobic respiration; in the absence of oxygen, it is called anaerobic respiration.

Expert Solution

Step 1

Yeast is a single-celled fungus that can respire aerobically as well as anaerobically to release energy from sugar molecules. This is called cellular respiration.

Aerobic respiration: In presence of oxygen, yeast respires aerobically in which glucose reacts with oxygen to form carbon dioxide, water, and 36 ATP molecules.

Anaerobic respiration: In absence of oxygen, yeast respire anaerobically in which glucose is converted into alcohol, carbon dioxide, and 2 ATP molecules.
