solong [7]

The end products of electron transport chain are:

Water

Adenosine triphosphate (ATP)

Explanation:

  • Most of the free energy released during the oxidation of  glucose to CO₂ is retained in the reduced co-enzyme NADH and FADH₂, generated during the kreb's cycle.
  • Electron are released from these co-enzymes and are eventually transferred to an oxygen molecule to form water.
  • These transfer of electron from co-enzymes to oxygen molecule occurs through a series of protein complexes in the mitochondrial membrane. And the process is termed as Electron Transport Chain.
  • The large amount of free energy is released during the oxidation of NADH and FADH₂ is used in the production of ATP

sertanlavr [38]

Answer:

limiting factor

Explanation:

In an ecosystem, certain factors hinder the growth or abundance of the population of organisms. These factors are called LIMITING FACTORS. Limiting factors, which can be biotic, food, drought, predation, disease etc, are factors that inhibits a population of organism from becoming enlarged. There are two types of limiting factors viz: density dependent (depends on size) and density independent (not dependent on size).

This is the case of a drought that dries up the stream that inhabits a population of salamanders. The drought causes the unavailability of water, which will ultimately have an effect on the growth of the salamander population. Hence, the DROUGHT is considered a LIMITING FACTOR.
