Answer 1

$\huge{\textsf{\textbf{\color{cyan}{answer:-}}}}$

there are basically three different ways by which glucose is oxidized to provide energy in various organisms.

$\large{\textsf{\textbf{\color{greenyellow}{aerobic:-}}}}$

1) 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

3)In the presence of oxygen- When breakdown of glucose is carried out in the Absence of oxygen in a cell, it is called as anaerobic respiration. Glucose is converted into a 3 carbon molecule called pyruvate which further breaks down in the absence of oxygen to give lactic acid and ethyl alcohol.
