Question

What are the different ways in which glucose is oxidized to provide energy inWhat is the role of saliva in the digestion of food?​

Answer 1

Answer:

Aerobic respiration : In this case pyruvate is broken down into water and carbon dioxide along with release of energy. It commonly occurs in mitochondria of cells. 2) Anaerobic respiration in yeast : In yeast cells during fermentation pyruvate is converted into ethanol and C02 in the absence of 02.

The digestive functions of saliva include moistening food, and helping to create a food bolus, so it can be swallowed easily. Saliva contains the enzyme amylase that breaks some starches down into maltose and dextrin. Thus, digestion of food occurs within the mouth, even before food reaches the stomach.

Answer 2

Answer:

Anaerobic Respiration: The anaerobic respiration process takes place in the absence of oxygen. For example: In yeast during fermentation. In this process the pyruvate is converted into ethanol and carbon dioxide.
