Explanation:
Observations allow us to collect data that we can connect back to the central problem. From this data we can start to form hypotheses (predictions on possible solutions or outcomes).
Answer:
b. Phosphofructokinase; Fructose-1,6-bisphosphatase
Explanation:
Glucagon is a hormone which functions to initiate gluconeogenesis whwreas insulin functions to initiate glycolysis.
Fructose-2,6-bisphosphate (F26BP) is an allosteric regulator of the <em>glycolytic and gluconeogenic enzymes phosphofructokinase-1 (PFK-1) and fructose-1,6-bisphosphatase (FBPase-1).</em>
It stimulates glycolysis and inhibits gluconeogenesis by binding to its allosteric site on phosphofructokinase-1 reducing its affinity for the allosteric inhibitors ATP and citrate .
It is formed by phosphorylation of fructose-6-phosphate catalyzed by <em>phosphofructokinase-2</em> and is broken down by <em>fructose-2,6-bisphosphatase </em>which are two separate enzymatic activities of a single, bifunctional protein (PFK-2/FBPase-2).
Phosphorylation of PFK-2/FBPase-2 due to glucagon release enhances its FBPase-2 activity thereby stimulating gluconeogenesis and inhibiting glycolysis.
Dephosphsorylation of PFK-2/FBPase-2 due to insulin release enhances its PFK-2 activity, thereby stimulating glycolysis and inhibiting gluconeogenesis.
Appalachian: A. Two continents colliding.
The Appalachian mountain range is an ancient example of a collision between two continental plates. Both plates have low density and little subduction occurs between them.
North American Cordillera: B. Terrane accretion
These form when two continents that collided bonded so tight that it forms a permanent land mass. If the continents would pull away from each other, the terrane stays intact.
Aleutian plate: D. Oceanic convergence
This is a type of convergence where one plate subducts beneath another plate. Between the two, the older plate is usually the one that subducts because it is usually more dense.
Andes mountain range: C. An oceanic plate and continental plate colliding.
In the collision between an oceanic and continental plate, the thinner and more dense oceanic plate subducts under the continental plate. The Andes mountain range was formed by the subduction of the Nazca Plate beneath the South american Plate.
In psychology, the manipulation is described a change done, in order to obtain a certain result, but this does not guaranty that the result would be seen in future.
In this case, the lady (Bethany) switches the diet of the dog. She thinks that switching the food of the dog can help the dog to lose weight. This may or may not be true.
So, this case is an example of manipulation.
Protein becomes denatured and cease to perform the work if structural changes occur because protein is highly specific in its function. It is stated that the function of the protein is determined by its structure. The proteins are the product of the continuous process of replication, transcription, translation and post-translational modifications. The information stored in it highly specific.
Protein binds with other molecules and perform various physiological functions as it has specific complementary attachment sites, the alteration in the structure would not let it bind to the target and hence desired result will not come out.
