During gluconeogenesis in the postabsorptive state, amino acids and lactate are converted to glucose. Amino acids are primarily derived from muscle protein breakdown and can be used as substrates for gluconeogenesis to maintain blood glucose levels. Lactate is another important precursor for glucose production via gluconeogenesis in the liver.

How are amino acids relate to gluconeogenesis?
Some amino acids can be converted into intermediates that are used in gluconeogenesis, the process by which the body synthesizes glucose from non-carbohydrate sources. This occurs when there is a need for glucose as an energy source, such as during fasting or prolonged exercise. The carbon skeletons of certain amino acids can serve as precursors for glucose production through gluconeogenesis.
How is the reduction of plasma alanine concentration caused by gluconeogenesis?
During gluconeogenesis, alanine is converted into pyruvate and then used in the process to produce glucose. This results in a decrease in plasma alanine concentration as the alanine molecules are utilized for energy production.
Glucose is converted to what during glycolysis?
Glucose is converted to pyruvate during glycolysis.
Where does the glocuse formation occur?
Glucose formation primarily occurs in plants during the process of photosynthesis, where carbon dioxide and water are converted into glucose using sunlight as the energy source. In animals, glucose is mainly formed through the breakdown of carbohydrates, fats, and proteins in the liver via processes like glycogenolysis and gluconeogenesis.
Gluconeogenesis describes the conversion of what?
Gluconeogenesis describes the conversion of non-carbohydrate sources, such as amino acids, glycerol, and lactate, into glucose. This process occurs primarily in the liver and to a lesser extent in the kidneys during times of low blood glucose levels.
Which of the choices below is not a source of glucose during the postabsorptive state?
Glycogen is not a direct source of glucose during the postabsorptive state, as it first needs to be broken down into glucose through glycogenolysis before it can be released into the bloodstream. Instead, gluconeogenesis from non-carbohydrate sources like amino acids, glycerol, and lactate primarily provides glucose during this state.
How are amino acids relate to gluconeogenesis?
Some amino acids can be converted into intermediates that are used in gluconeogenesis, the process by which the body synthesizes glucose from non-carbohydrate sources. This occurs when there is a need for glucose as an energy source, such as during fasting or prolonged exercise. The carbon skeletons of certain amino acids can serve as precursors for glucose production through gluconeogenesis.
The Cori cycle involves the interconversion of?
lactate and glucose between the muscle and liver. During intense exercise, skeletal muscles produce lactate, which is sent to the liver to be converted back into glucose through gluconeogenesis. This glucose is then transported back to the muscles for energy production.
What is the process of making glucose from a non glucose source?
Glucose can be made from non-glucose sources through a process known as gluconeogenesis. This process primarily occurs in the liver and kidneys and involves converting substrates like pyruvate, lactate, glycerol, and certain amino acids into glucose. Gluconeogenesis helps maintain blood glucose levels during fasting or low carbohydrate intake.
How does the body make glucose from protein?
Glucose can't be converted to proteins by addition of chemicals . But during metbolic reaction products formed from glucose are used to make amino acids by addition of amino group which form proteins .
When are amino acids used instead of glucose?
Amino acids are used instead of glucose for energy production during prolonged fasting or starvation when glucose levels are low. Amino acids can be converted into glucose through a process known as gluconeogenesis to maintain blood sugar levels and provide energy to cells.
How is the reduction of plasma alanine concentration caused by gluconeogenesis?
During gluconeogenesis, alanine is converted into pyruvate and then used in the process to produce glucose. This results in a decrease in plasma alanine concentration as the alanine molecules are utilized for energy production.
Two regions of cori cycle and two fates of the glucose?
Cori cycle occurs in the liver and muscle tissues. In the liver, lactate is converted back to glucose during gluconeogenesis for energy production or storage as glycogen. In muscle tissues, glucose is converted to lactate during intense physical activity to regenerate NAD+ for continued ATP production.
What is a source of glucose for blood?
the majoe two sources are from the diet and during fasting states by gluconeogenesis
Glucose is converted to what during glycolysis?
Glucose is converted to pyruvate during glycolysis.
What is the difference between glycolysis and gluconeogenesis?
Glycolysis is the breakdown of glucose into pyruvate, generating ATP and NADH, while gluconeogenesis is the synthesis of glucose from non-carbohydrate precursors such as amino acids, lactate, or glycerol. Glycolysis is a catabolic process, whereas gluconeogenesis is an anabolic process that occurs mainly in the liver and kidneys to maintain blood glucose levels during fasting or low carbohydrate intake.
What is the formation of a new glucose molecule?
A new glucose molecule is formed through the process of photosynthesis in plants. During photosynthesis, carbon dioxide and water are converted into glucose and oxygen using sunlight as the energy source. This process involves a series of chemical reactions that take place in the chloroplasts of plant cells.
