What in gluconeogenesis during the postabsorptive state amino acids and what are converted to glucose?
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.
Is the transition state the slowest step in a reaction mechanism?
The transition state is not a step in a reaction mechanism; it is a high-energy state that exists at the peak of the reaction potential energy diagram. The slowest step in a reaction mechanism is often referred to as the rate-determining step, which has the highest activation energy and determines the overall rate of the reaction.
State wether a nuclear fusion is a chemical reaction or a nuclear reaction?
Nuclear
What do mean by extent of reaction?
Extent of the reaction measures how far a reaction will proceed before establishing equilibrium state .
What hormone stimulates lipogenesis?
Insulin is the hormone that stimulates lipogenesis, the process where the body converts excess carbohydrates into fat for storage. Insulin promotes the uptake of glucose from the blood into adipose tissue where it can be converted into fatty acids and stored as triglycerides.
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.

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.
What does lipogenesis generally begin with?
Acetyl-CoA
State the effects of the hormones on lipogenesis?
As widely known, hormones control body metabolism. Although nutritional status and homones profile will influence lipogenesis rate, for simpliticy, insulin action along with glucose availability may be taken as master controlers in lipogenesis. These two factors signal cells by switching on and off AMPk-dependent processes, for exemple: low glucose and insulin levels will activate AMPk, which in turns inhbits energy-requiring processes and stimulates energy-releasing processes - in this case, lipogenesis will be switched off.

When does lipogenesis occur most often?
Lipogenesis occurs most often during times of excess energy intake, particularly when there is a surplus of carbohydrates. This process is facilitated by insulin, which promotes the conversion of glucose into fatty acids for storage as triglycerides in adipose tissue. Additionally, lipogenesis is more active after meals when blood glucose levels are elevated. Overall, it is a key metabolic pathway for energy storage in the body.
What are the key differences between an intermediate state and a transition state in a chemical reaction?
An intermediate state is a stable molecule formed during a chemical reaction, while a transition state is a high-energy, unstable state that exists briefly during the reaction. The intermediate state is a product of the reaction, while the transition state is a point where the reactants are in the process of forming products.
What is the production of a new fatty acid called?
The production of a new fatty acid is called lipogenesis. It is a process where fatty acids are synthesized from acetyl-CoA and malonyl-CoA, which are precursors derived from carbohydrates and proteins. Lipogenesis occurs mainly in the liver and adipose tissue.

In what state is hydrogen in the reaction?
solid
State wether a nuclear fusion is a chemical reaction or a nuclear reaction?
Nuclear
What does Hesses law state?
The enthalpy of a reaction is the sum of the enthalpies of intermediate reaction.
What does energy need to add to a reaction for it to reach its highest state?
Every reaction in which bonds are broken will have a high energy transition state.
