Question

what are the different ways in which glucose is oxidised to provide energy in various organisms ?

Answer 1

Hey Mate ✌

Here's your answer,

At First the glucose ( C6H12O6) is converted into Pyruvate ( 6 Carbon molecule). It breaks in cytoplasm of the cells of the organisms.

Further.....

1) Anaerobic Respiration : This process takes place in the absence of oxygen. e. g. yeast in fermentation. In this case pyruvate is converted into ethanol and carbon dioxide.

2) Aerobic respiration : Here break down of pyruvate takes place in the presence of oxygen to give 3 products Carbon dioxide, water, and energy.

3) Lack of oxygen : Sometimes when there is lack of oxygen in muscles pyruvate is converted into lactic acid and cramp takes place.

Answer 2

There are two different types of respiration for oxidation of glucose:-

(a) Aerobic respiration: In this process, complete oxidation of glucose is involved hence, optimum output of energy is achieved. This process takes place in presence of oxygen.

(b) Anaerobic respiration: this process takes place in the absence of oxygen hence, complete oxidation of glucose does not take place. Usually, bacteria shows anareobic respiration. Even sometimes in our calf muscles anaerobic respiration takes place.
