A glucose molecule is completely broken down upon completion of glycolysis and the citric acid cycle. however, these two process
Blababa [14]
In both the process of glycolysis and the citric acid cycle; yes ATP is produced albeit in a very low amount. Another byproduct of these pathways are the production of reducing compounds such as reduced nicotinamide adenine dinucleotide (NADH) and reduced flavin adenine dinucleotide (FADH). These reducing compounds are used in the electron transport chain to produce a proton gradient, and with a proton gradient, the enzyme ATP synthase will synthesize ATP from ADP and inorganic phosphate.

How does biodiversity contributes to the sustainability of a natural environment
yaroslaw [1]

Explanation:

A high level of biodiversity leads to a better sustainability of the natural environment.

  • Biodiversity is the variation of plant and animal species in an ecosystem.
  • The natural environment deals with the living and non-living part of the ecosystem.
  • A wide range of diversity in the ecosystem brings in broader level of interaction among the different constituents of the environment.
  • Biodiversity ensures there is no over dependence on a particular resource in the environment. Organisms have access to a pool of resources.
  • In adverse times, it ensures that quite a number of organisms are still able to live and thrive well.
