Answer: The electrons in an atom that take part in chemical bonding are the electrons in the outermost shell and they are called valence electrons.
Explanation: An atom is composed of three particles: protons, neutrons and electrons. The protons and neutrons occupy the centrally located nucleus while the electrons are located in the empty space outside the nucleus. Electrons are distributed around the nucleus in paths called electron shells. The electrons in the outermost electron shells are called the valence electrons. The valence electrons are the electrons that participate in chemical bonding. During chemical bonding, the valence electrons are either transferred from one atom to another or the valence electrons are shared between two atoms. A type of chemical bonding in which there is a complete transfer of valence electrons from an atom of a metal to an atom of a non-metal so that can attain octet or duplet structure of noble gases is called electrovalent or ionic bonding. A type of chemical bonding in which there is sharing of electrons between two atoms of non-metals so that both can attain the octet or duplet structure of noble gases is called covalent bonding.

Answer:
flux
Explanation:
- The rate by which the turnover of the molecules takes place in a metabolic pathway that regulates the flow of material is termed as metabolic flux or simply flux.
- The various enzymes that are involved in the metabolic pathway are responsible for regulating the flux.
- The flux varies with the different states of activity of a person and it is important for the regulation of metabolic activities as well as maintain the homeostasis of the body.
- The mathematical expression to calculate the flux is :
J = Vf - Vi
Where J = flux of metabolites
Vf = rate of the forward reaction
Vi = rate of the reverse reaction
Answer:
A) RNA information is copied into DNA
Answer:
Begin to cross the membrane while still being synthesized-C
Explanation:
The Endoplasmic Reticulum is a part of the endomembrane system of the cell which is mostly reponsible for the synthesis and modification of proteins, although synthesis of lipids in plant and animal are carried out here
For more synthesis of proteins, it
needs to be further transported into the Rough endoplasmic reticulum- the designated site for secretion after synthesis of proteins.
Also it has been found out that when this proteins enter the Endoplasmic Reticulum, they start to cross the membrane while still being synthesized.
