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.
The thyroid gland controls the metabolic rate.
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.
The addition of a lactose molecule to the Lac repressor protein is an example of post-translational control in lac operon regulation. This modification prevents the Lac repressor from binding to the operator region, allowing for the transcription of the genes involved in lactose metabolism.
The phloem parenchyma cell contains a nucleus which helps in regulating its metabolic activities. These cells are involved in maintaining the osmotic pressure gradient within the sieve cell, aiding in the movement of sugars and nutrients in the phloem.
The endocrine system is primarily involved in growth and regulation through the release of hormones that control growth and development. The skeletal system also plays a significant role in growth by providing structural support and facilitating bone development and growth.
Yes, enzymes that undergo negative feedback regulation typically have other important functions in the cell or organism. These enzymes are often involved in key metabolic pathways and play critical roles in maintaining cellular homeostasis and carrying out essential biological processes. The negative feedback regulation helps control the rate of these enzymatic reactions to ensure optimal function.
Enzymes act as catalysts that speed up chemical reactions in metabolic pathways by lowering the activation energy required for the reactions to occur. They are specific to the substrates they interact with, allowing for precise control and regulation of metabolic processes. Enzymes can be turned on or off in response to cellular signals, helping to maintain metabolic balance in the cell.

No, antlers do not help control body temperature. Antlers are primarily used for display during mating season, establishing dominance, and defense. Body temperature regulation is mainly controlled by the animal's circulatory system and metabolic processes.
