<span>As the human population rises, the chances of a mass extinction event are also escalating.

Historically, an increase in human population correlates with the extinction of various species. The more the human population expands and the more habitats are destroyed to enhance living standards, the greater the risk of mass extinction becomes. </span>

Response:

Pyruvate

Explanation:

Glycolysis is the metabolic pathway in which glucose is converted to pyruvate.

The process involves ten enzyme-mediated steps, yielding two molecules of pyruvate from one glucose molecule.

Step 1: Phosphorylation of glucose results in glucose-6-phosphate

Step 2: Glucose-6-phosphate transforms into fructose-6-phosphate

Step 3: Fructose-6-phosphate is further phosphorylated to yield fructose-1,6-bisphosphate

Step 4: This intermediate is then cleaved into glyceraldehyde-3-phosphate and dihydroxyacetone phosphate

Step 5: One molecule of dihydroxyacetone phosphate is converted into another glyceraldehyde-3-phosphate.

Step 6: Two glyceraldehyde-3-phosphate molecules are modified to produce two 1,3-bisphosphoglycerate molecules

Step 7: Conversion of these to 3-phosphoglycerate occurs next

Step 8: This is followed by conversion to two molecules of 2-phosphoglycerate

Step 9: Following this, they are converted into two phosphoenolpyruvate molecules

Step 10: Finally, two of these are converted into pyruvate, the glycolysis product.

Thus, the presence of pyruvate in red blood cells can indicate their capacity to undergo glycolysis
