Intrinsic regulation is when the products of the reaction regulate the rate of the reaction, acting as regulators (usually allosteric) . i.e it is self-limiting.
Pyruvate + CoASH + NAD+ --> Acetyl-CoA + NADH2 + CO2
This is an example of the bridging reaction wherein pyruvate reacts with CoA and NAD+ to form Acetyl-Coa. The intrinsic regulator here is Acetyl-Coa as if it increases in concentration it inhibits the reaction (following Le Chateliers principle).
NADH2 is also an INTRINSIC regulator here.

Why is allosteric regulation important to a cell?
Allosteric regulation is crucial for cellular function because it allows enzymes and proteins to be modulated in response to changes in the cellular environment. This regulation enhances or inhibits enzyme activity through the binding of molecules at sites distinct from the active site, enabling fine-tuning of metabolic pathways. It promotes efficiency and adaptability, ensuring that cellular processes can respond dynamically to varying conditions and demands. Consequently, allosteric regulation is integral for maintaining homeostasis and optimizing metabolic responses in a cell.
Which of the following is not used to determine metabolic activity?
Temperature is not typically used to determine metabolic activity, as metabolism is more directly influenced by factors such as enzyme activity, substrate availability, and hormonal regulation. Temperature can indirectly affect metabolic rate by influencing enzyme function and reaction rates.
Is glycolysis regulation effective?
Yes, glycolysis regulation is effective as it ensures cellular energy production is matched to the cell's metabolic needs. Key regulatory enzymes, such as hexokinase, phosphofructokinase-1, and pyruvate kinase, are influenced by various metabolites and energy status signals. This regulation allows for the fine-tuning of glucose breakdown based on factors like ATP levels, ensuring efficiency and preventing waste. Overall, such control mechanisms are crucial for maintaining metabolic homeostasis.
What is the central organ for regulation of metabolism?
Thyronin also Thyroxine
What organ is called the metabolic capital of the body?
The liver is often referred to as the metabolic capital of the body due to its central role in various metabolic processes. It is responsible for the regulation of glucose levels, the synthesis of important proteins, and the detoxification of harmful substances. Additionally, the liver plays a key role in lipid metabolism and the storage of vitamins and minerals, making it vital for overall metabolic health.
Explain what is regulation of metabolic pathway?
Metabolic pathway is the sum total of all the biochemical reactions in our body. It regulation or control is done by our genetic system through both hormonal and nervous control.
What are the nutrients involved in metabolic regulation and control include?
vitamins and mineral
Special proteins that are involved in metabolic regulation are called?
D. Enzymes :)
What has the author KEITH N FRAYN written?
KEITH N. FRAYN has written: 'METABOLIC REGULATION: A HUMAN PERSPECTIVE'
Which of the following statements about feedback regulation of metabolic pathways is correct?
Feedback regulation of metabolic pathways involves the inhibition of an enzyme by the end product of the pathway. This helps maintain homeostasis by preventing the overproduction of metabolites. This process is important for ensuring that a cell or organism does not waste resources on unnecessary synthesis.
