AP BIOLOGY

Detailed explanation-1: -Anaerobic respiration is the breakdown of glucose in the absence of oxygen. In yeast, the glucose breaks down anaerobically to produce alcohol as the end product and carbon dioxide gas as the byproduct.

Detailed explanation-2: -In yeast, the end products of anaerobic respiration are ethyl alcohol, carbon dioxide and ATP (Adenosine triphosphate).

Detailed explanation-3: -Anaerobic respiration in yeast cells produces carbon dioxide, ethanol and energy.

Detailed explanation-4: -Some organisms such as yeasts only undergo anaerobic respiration and do not require Oxygen. During anaerobic respiration pyruvate from glycolysis is instead made into Lactate in animals, and Ethanol and Carbon Dioxide in yeast. This is why when yeast is added to aa cake bubbles form in the bread and the cake rises.
