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

evablogger [386]

The border between the transparent edge of the cornea and the white of the fibrous sclera is the limbus. The limbus contains clusters of limbal stem cells that help to maintain the corneal epithelium and to regulate corneal transparency and vision throughout life. The limbus also acts as a boundary that protects the conjunctiva and its blood vessels.

What happens when an electrical gradient and a chemical gradient are applying opposite forces to active transport?
Ierofanga [76]

Answer:

Option B, they negate each other

Explanation:

Electrical gradient force is more or less equal to the chemical gradient during an active transport. The number of electron produced during the establishment of chemical gradients, were transferred through the cellular circuit to produce electrical gradient of an equivalent amount in opposite path.

Thus, both electrical and chemical gradient are opposite to each other and hence they negate out each other.
