Bonding that involves the exchange or gain and loss of electrons is known as
natulia [17]
ionic bonding.
Ionic bonding<span> is a type of </span>chemical bond<span> that involves the </span>electrostatic attraction<span> between oppositely charged </span>ions<span>, and is the primary interaction occurring in </span>ionic compounds<span>. The ions are atoms that have gained one or more </span>electrons<span> (known as </span>anions<span>, which are negatively charged) and atoms that have lost one or more electrons (known as </span>cations<span>, which are positively charged). This transfer of electrons is known as </span>electrovalence<span> in contrast to </span>covalence<span>. In the simplest case, the cation is a </span>metal<span> atom and the anion is a </span>nonmetal<span> atom, but these ions can be of a more complex nature, e.g. molecular ions like NH</span>4+<span> or SO</span>42−<span>. In simpler words, an ionic bond is the transfer of electrons from a </span>metal<span> to a </span>non-metal<span> in order to obtain a full valence shell for both atoms.</span>

What is carbon fixation, and how does it relate to photosynthesis?
nata0808 [166]

Answer:

It is the conversion of CO2 into organic compounds and it forms 3-PGA.

Explanation:

Carbon fixation is one of the three stages in which the light independent phase of photosynthesis is divided into. It is the process whereby CO2, an inorganic source of carbon, is accepted by RUBP, leading to the formation of a 6-carbon compound that disintegrates into two 3-carbon molecules due to its instability.

The 3-carbon compounds are 3-phosphoglycerate or commonly known as 3-PGA. The carbon fixation stage is followed by reduction stage.
