Question

8. Explain glucose pathway.​

Answer 1

sugar , is glucose path way

Answer 2

Answer:

At first, glucose is broken down into three-carbon molecule called pyruvate. Pyruvic acid is converted into carbon dioxide, and water thus releasing a lot of energy. ... (ii) Anaerobic respiration takes place in the cytoplasm in the absence of oxygen.

Glucose is broken down into a three carbon molecule called pyruvate in the cell cytoplasm. Pyruvate is further broken down by different ways to provide energy in various organisms. Pyruvate is broken down in different ways in different organisms

                                                                                                                                                                 

i.In yeast cells, during fermentation, pyruvate is converted into ethanol and carbon dioxide in the absence of oxygen.

ii. In mitochondria, breakdown of pyruvate takes place in presence of oxygen to give rise three molecules of carbon dioxide and water.

iii. Sometimes, when there is lack of oxygen, especially during vigorous activity, in our muscles, pyruvate is converted into lactic acid. Concept insight: Students should know various types of respiration.
