weeeeeb [17]

He needs to be careful to document his sources about the problem of invasive species.

<h3>What is Invasive species?</h3>
  • An introduced organism that overpopulates and damages its new environment is referred to as an invasive species.
  • Even though the majority of introduced species are neutral or helpful to other species, invasive species have a negative impact on habitats and bioregions, harming their ecology, the environment, and/or their economy.
  • Invasive species are one of the largest issues our natural environments have ever faced.
  • Invasive species have the potential to proliferate rapidly in the absence of their natural predators, displacing native species, destroying ecosystems, and incurring high costs.
  • This increase is frequently attributed to growing global trade, manufacturing specialization, and linkages to previously remote areas.
  • Additionally, the extension of existing imported specie's ranges is made possible by climate change.

What stage of respiration immediately follows the process depicted below? Two pyruvate molecules undergo a chemical reaction, co
Nadya [2.5K]

Answer:

Electron transport chain

Explanation:

Cellular respiration is the process whereby glucose is broken down in the cell to yield energy in form of ATP. This process, which is important to the metabolic functioning of every organism, occurs in three major stages namely: glycolysis, kreb's cycle and electron transport chain (ETC).

According to this question, a stage of respiration is described as follows:

- Two pyruvate molecules undergo a chemical reaction, combining with coenzyme A to form two acetyl-CoA molecules.

- Two carbon dioxide molecules and two NADH molecules are formed as a result of this process.

The process depicted above is KREB'S CYCLE of cellular respiration, hence, the stage of respiration that immediately follows the process is called ELECTRON TRANSPORT CHAIN (ETC).
