Question

name two different ways in which glucose is oxidised to provide energy in various organisms​

Answer 1

1. Anaerobic respiration:

• Here the first step is the break-down of glucose into a three-carbon molecule called pyruvate.
• This process takes place in the cytoplasm.
• Further, the pyruvate may be converted into ethanol and carbon dioxide.
• This process takes place in yeast.  

2. Aerobic respiration:

• During aerobic respiration, first glucose is broken down into pyruvate and then the three-carbon pyruvate molecule is broken down to give three molecules of carbon dioxide and water.

Answer 2

The two ways are anaerobic and aerobic respiration.
