What’s needed to build a neutral atom?

Chemistry

Answer:

Protons are positively charged, electrons are negatively charged (with the same magnitude of charge per particle as a proton). Neutrons have no charge. Now, in a "neutral atom", the number of protons must be equal to the number of electrons, otherwise it would not be neutral.

Determine if the phrases below are true for catabolic pathways only, anabolic pathways only,or can apply to both pathways, by so

Ivan

Answer:

Catabolic pathways;

Pathway produces more ATP than it consumes

Supplies NADH for oxidative phosphorylation

Anabolic pathways only:

Consumes more ATP than it produces

Can require reducing agent

Both pathways;

At least one enzyme is regulated

All reactions are catabolized by enzymes

One or more reactions are endergonic without ATP

Explanation:

Catabolic pathways;

Complete oxidation of glucose and then produces more ATP. Oxidative phosphorylation is an example of catabolic pathway.

From the given following conversions are considered as catabolic pathways.

Pathway produces more ATP than it consumes

Supplies NADH for oxidative phosphorylation

Anabolic pathways:

Anabolic pathways produces new molecules and it requires energy in the form of ATP for the formation of new bonds.

From the given following conversions are considered as anabolic pathways.

Consumes more ATP than it produces

Can require reducing agent.

Both pathways;

Metabolic pathways are occuring in the cell only few enzymes are regulate these pathways.

At least one enzyme is regulated

All reactions are catabolized by enzymes

One or more reactions are endergonic without ATP

2.41 What is an ionic compound? How is electrical neutrality maintained in an ionic compound?

kiruha [24]

Answer:

Explanation:

An ionic compound is a compound in which electrovalent bonds joins the atoms together. Here, electrons move from a less electronegative atom to a more electronegative one. The formation of ionic bonds involves the transfer of elecrons.

The transfer of electrons makes the atoms charged i.e ionized. These oppositely charge ions establishes an electrostatic force of attraction to form the ionic compounds.

How is electrical neutrality maintained in an ionic compound?

Electrical neutrality is maintained in an ionic compound because the compound is made up of ions in which the net charge is zero. There is a transfer of electrons which is completely recieved by the more electronegative atom.
