A waterborne pollutant can have different effects on aquatic life depending on the nature of the pollutant. A pollutant at lower levels can have minimal or no effect on aquatic life. However, when the concentrations of the pollutant are high, the population of aquatic organisms can be greatly reduced. There are also times when pollutants at lower concentrations cause significant damage. An organism can consume another organism that has absorbed small amounts of the pollutant. As the consumer takes in more of the contaminated organism, the pollutant is magnified in the body of the consumer resulting in lethal concentrations. This is called biomagnification.
Here is the equation for cellular respiration if that helps.
Answer:
Glycolysis is the first step of the cellular respiration in an organism which is metabolic pathway that is completed in the cytosol of the cell that leads to the converting glucose to the pyruvate in order to produce energy in form of ATP:
1. Glucose-6-phosphate is ---> fructose-6-phosphate
2. fructose-6-phosphate ---> fructose-1,6-biphosphate
3. fructose-1,6-biphosphate ---> glyceraldehyde-3-phosphate(GAP) and dihydroxyacetone phosphate (DHAP).
4. GAP is oxidised ----> 3-bisphosphoglycerate + NADH
5. 3-bisphosphoglycerate ----> 1,3-bisphophoglycerat
6. 1,3-bisphophoglycerate ----> 3-phosphoglycerate
7. 3-phosphoglycerate ----> 2-phosphoglycerate
8. 2-phosphoglycerate ----> phosphoenolpyruvate (PEP)
9. phosphoenolpyruvate to ADP ----> pyruvic acid + ATP
Formation of ATP occurs in both pathways or process that are respiration and fermentation. Fermentation is a catabolic pathway leads to the degradation of sugars (partial) that result in the gain of energy and this energy are absorbed in ATP. There are difference of the amount of energy or ATP produce in these process in respiration 38 ATP are produced whereas during fermentation only 2 ATP are produced.
