Why does it make good metabolic sense for phosphoenolpyruvate carboxykinase, rather than pyruvate carboxylase, to be the primary target for the regulation of gluconeogenesis at the level of control of enzyme synthesis?.
Because oxaloacetate is required by the body for other metabolic pathways, it is best to regulate gluconeogenesis at the level of synthesis of phosphoenolpyruvate carboxykinase.
What is metabolic regulation?Metabolic regulation refers to the various mechanisms employed by the cells and tissues to regulate metabolic activities in the body.
One form of metabolic regulation is gene expression regulation.
Phosphoenolpyruvate carboxykinase converts oxaloacetate to phosphoenolpyruvate while pyruvate carboxylase converts pyruvate to oxaloacetate.
Since oxaloacetate is required by the body for other metabolic pathways, it makes sense to regulate gluconeogenesis by regulating level of synthesis of phosphoenolpyruvate carboxykinase.

Facilitated diffusion is a type of
passive transport, which means it
does not require energy.
Which of the following is an
example of facilitated diffusion?
A. liquid molecules colliding
B. plants bringing nutrients into their roots
from the soil
C. protein channels embedded in the cell
membrane
D. the sodium-potassium pump actively
bringing sodium and potassium into the cell
Answer:
B
Explanation:
The plant doesn't use energy to bring nutrients into the roots. The concentration of nutrients is higher in the soil than in the root, so they passively move into the root to make the concentrations equal.

What is Springs structure?The Spring framework, sometimes known as Spring, has arisen as a response to all of these issues.
This framework eliminates the complexity associated in designing enterprise applications using EJB by leveraging a variety of innovative techniques, including as dependency injection (DI), aspect-oriented programming (AOP), and plain old Java objects (POJO).
Dependable, and scalable enterprise applications can be created by Java EE 7 developers using the open source, lightweight Spring framework. The primary goal of this framework is to offer you a variety of tools for managing your business objects.

How do cells selectively accept the material?In cells having a membrane that is selectively permeable, no molecule is enter or lives in the cell. It has several protein transporters which allow the molecule to enter the cell, this maintains the cell's function.
Some inhibitors and toxic materials are responsible to inhibit general cellular functions, like metabolism, and DNA synthesis. Metabolism products made by the cell are necessary and do not allow to escape from the cell.
