Janis tore a ligament in her ankle. Until the injury heals, she is at most risk for which of the following? dislocating bones lo
bulgar [2K]

Answer:

The correct answer is ''dislocating bones.''

Explanation:

When the bone " pops out" or dislodges from its place (joint), a dislocation occurs. An ankle dislocation, like any other joint, occurs when the 2 articular surfaces of the ankle separate, in this case when the talus ( together with the rest of the foot) " pops out of place" and is no longer in contact with the surface of the tibia-fibula. This leads to the complete breakdown of the ligaments that hold the joint in place, causing the bones to " pops out." Producing significant deformities in the affected joint.

Much of the regulation of gluconeogenesis is a result of the inhibition of?
matrenka [14]

The suppression of glycolysis is responsible for a large portion of the control of gluconeogenesis.

Discussion about the statement:

The cytosol is the site of all glycolysis and gluconeogenesis processes. The rate at which glucose is produced in the body is inversely related to the intake of carbohydrates. The suppression of glycolysis is responsible for a large portion of the control of gluconeogenesis.

Fructose 2,6-bisphosphate is an intermediate that plays a crucial role in controlling both glycolysis and gluconeogenesis. This metabolite's presence can promote glycolysis and prevent gluconeogenesis.

Control of Gluconeogenesis and Glycolysis

  • At various crucial stages of glycolysis and gluconeogenesis, metabolic control takes place. The catalysts that accelerate each of these stages can be activated or inhibited by outside forces, for example, the quantity of a molecule that comes after. The conversion of glucose and ATP into glucose 6-phosphate is the first controlled step in glycolysis. Keep in mind that hexokinase catalyzes this process.
  • High levels of blood glucose, AMP, and low levels of cellular ATP all trigger the activation of hexokinase. In other words, the glycolysis process is enhanced when blood glucose levels are high. Whenever cellular ATP levels are low and AMP levels are high, glycolysis is also increased. Both of these instances show that the cell is short on energy and may be directly influenced to create additional energy.
