Synthesis of glucose from pyruvate during the Cori cycle occurs primarily in the__________.
Gemiola [76]
Gluconeogenesis is a ubiquitous process, present in plants, animals, fungi, bacteria, and other microorganisms.[2] In vertebrates, gluconeogenesis takes place mainly in the liver and, to a lesser extent, in the cortex of the kidneys. In ruminants, this tends to be a continuous process.[3] In many other animals, the process occurs during periods of fasting, starvation, low-carbohydrate diets, or intense exercise. The process is highly endergonic until it is coupled to the hydrolysis of ATP or GTP, effectively making the process exergonic. For example, the pathway leading from pyruvate to glucose-6-phosphate requires 4 molecules of ATP and 2 molecules of GTP to proceed spontaneously. Gluconeogenesis is often associated with ketosis. Gluconeogenesis is also a target of therapy for type

  • A unicellular organism is an organism made up of a single cell.
  • A multi-cellular organism is made up of several cells.
  • A cell is a very small microscopic structure.
  • It is usually described as the fundamental unit of life.
  • Due to its small size, the naked eyes cannot see it
  • The invention of the microscope opened up the world of cells.
  • Since they have been around for a long time, distinction of cells would have been made possible at those times using a microscope.
