Answer:
hippocampal place
Explanation:
A type of cell that fires when rats are in a specific location as opposed to some other locations are known as place cells.
Generally, place cells are specially shaped neurons whose origin is the hippocampus. These neurons fire or become more active when animals are in certain locations in its environment, as opposed to their overall environment.
The cells are from regions CA1 and CA3 of the hippocampus and collectively act as a cognitive representation of these locations where they are limited to firing. The locations where the neurons are limited to firing are referred to as place fields.
Hence,<u> the cells found in the rat as shown by the illustration are referred to as the place cells whose origin is the hippocampus.</u>
Answer:
From the point of view of the type of molecule that is obtained after the degradation of the hydrocarbon skeleton, amino acids can be classified as: glucogenic and ketogenic. The main difference between glucogenic amino acids and ketogenic amino acids is that glucogenic amino acids can be converted to pyruvate or other glucose precursors, while ketogenic amino acids can be converted to acetyl CoA and acetoacetylCoA.
Explanation:
Glucogenic amino acids are amino acids that break down to pyruvate, alpha-ketoglutarate, succinyl Co-A, fumarate, and oxaloacetate and are so named because the synthesis of glucose from these molecules is feasible. Both pyruvate and the Krebs cycle intermediates noted above can be converted to phosphoenolpyruvate and subsequently glucose through gluconeogenesis.Ketogenic amino acids are the amino acids that generate acetyl-CoA or acetacetyl-CoA and are called by this name because they can cause ketone bodies. Since mammals lack the proper enzyme system, these compounds can never be used as precursors for glucose biosynthesis. Of the twenty universal amino acids, fourteen are purely glucogenic and two are purely ketogenic (leucine and lysine). The remaining four (isoleucine, phenylalanine, tryptophan and tyrosine) are glucogenic and ketogenic simultaneously since a part of the hydrocarbon skeleton originates precursors for the biosynthesis of glucose (pyruvate or Krebs cycle intermediates) and the other part acetyl-CoA or acetacetyl -CoA.
