Dissection is one of the procedures through which scientists can find out about the internal parts of life science specimens.
Dissection in its literal terms is the cutting down of an object. The process involves cutting the parts and organs of an organism to study its anatomical structures. The process should be performed carefully so that the anatomy is not ruined and results are not misinterpreted.
Specimens are the samples related to living organisms used to visualize and study about them. These specimens can be deceased living organisms that are carefully preserved using chemicals. Other structures of the living organisms like their teeth, skin, exoskeleton, horns, etc. can also be considered a specimen.

Answer:
Explanation:
Cellular respiration generally involves breaking down of large organic molecules to release ATP (energy). Citric Acid cycle, also known as Kreb's cycle or Tricarboxylic acid cycle is the second stage of the cellular respiration (unique to aerobic organisms). Citric acid cycle occurs in the intracellular space or matrix of the mitochondria of eukaryotes.
Glycolysis, which is the first step of cellular respiration, produces pyruvate which is then converted to Acetyl CoA in order to enter the Kreb's cycle by first combining with oxaloacetate. Generally, citric acid cycle involves an eight-steps reaction consisting of series of reduction-oxidation, hydration, dehydration, decarboxylation reactions, with each step catalyzed by different enzymes.
In a nutshell, oxaloacetate is generated back at the completion of the cycle alongside 2 molecules of CO2, one GTP/ATP molecule and electron donors; NADH2 and FADH2. These reduced electron donors enter the third step of aerobic cellular respiration and act as the first electron donor in the Electron transport chain.
