Question

how would you demonstrate that yeast can respire both aerobically and anaerobically

Answer 1

Answer:

When active (live) yeast has both sugar and oxygen available to it, it 'breathes' by a process called aerobic respiration. If no oxygen is available, yeast will switch over to a process called anaerobic respiration - in this process, glucose (sugar) is fermented to produce energy, carbon dioxide, and ethanol.

Hope this helps and please do mark as the brainliest.

Answer 2

Aerobic And  Anaerobic Respiration

Explanation:

• Yeast can breathe both aerobically and anaerobically.
• It gets more vitality from oxygen consuming breath than anaerobic breath. Without air, it keeps on breathing anaerobically.
• Yeast produces water and carbon dioxide vigorously and anaerobically, it produces ethanol.  
• Certain microscopic organisms are obligately anaerobic and can exist just in sans O2 conditions. Conversely, numerous living beings can just make due in aerobic conditions.  
• The anaerobic breath pathway in yeast cells during this procedure, pyruvic corrosive from glycolysis is changed over to ethanol and carbon dioxide.
• Pathways that oxidize glucose to create ATP vitality utilizing an option that is other than O² as a definitive hydrogen acceptor.
