Question

discuss the breakdown of glucose in living being

Answer 1

Hey
here is answer
In the very first stage the Glucose which is a 6-carbon molecule is breaks into pyruvate which is a 3-carbon molecule in the cytoplasm.  After that they are broken down by three different pathways to release energy.

(i) In the absence of oxygen in Yeast.

(ii) In the lack of Oxygen in Human Muscles.

(iii) In the presence of oxygen in mitochondria.

Answer 2

Heya!!! ✌️✌️

Here is your answer dear.....

in living organisms, the oxidation of glucose contributes to a series of complex biochemical reactions which provides the energy needed by cells. The first step in the breakdown of glucose in all cells is glycolysis, producing pyruvate which is the starting point for all other processes in cellular respiration. In cells where oxygen is present (aerobic respiration) these processes have been modeled in the TCA or Krebs cycle. A major part of the use of the energy from glucose oxidation is the conversion of ADP to ATP, with the energy-rich molecule ATP being subsequently used as the energy currency of the cell.

I HOPE THIS WILL HELP YOU OUT....

HAVE A GREAT DAY DEAR.....
