Answer:
The explanation of the processes in which pigments are involved (capturing light and forming ATP and NADPH) is given in the following paragraphs)
Explanation:
Pigments are molecules with the capacity of absorbing light. Each pigment captures light of a specific wavelength. Plants contain different types of pigments like chlorophylls, xanthophylls, carotenoids, and others.
Chloroplasts (organelles present in cells of plants), contain pigmants that absorb solar radiation, triggering a series of reactions collectively known as photosynthesis. When light incides on a pigment, an electron of this molecules is excitated, goes into another level of energy and starts to pass through a series of carrier molecules to finally to a final aceptor of electrons. During this transport, part of the energy contained in the electron is used to generates a hydrogen gradient that provides energy. As a result of these processes, a molecule that is called NADP+ accepts two electrons and an hydrogen to form NADPH, while another molecule known as ADP captures an atom of phosphorous and gives rise to ATP (through the action of a protein called ATP sintase)..
Carbohydrates are biological molecules made of carbon, hydrogen, and oxygen in a ratio of roughly one carbon atom (

Carbohydrate chains come in different lengths, and biologically important carbohydrates belong to three categories: monosaccharides, disaccharides, and polysaccharides.
Answer:
Explanation:
Chlorine has electronic configuration of 2 , 8 , 7
In n = 3 there are 7 electrons out of which 2 are in s , and 5 are in p . But out of 5 electrons in p , one electron jumps into d orbital . so the electronic configuration becomes as follows
= 7
These orbitals like sp³d hybridise to form 7 degenerate orbitals out of which 2 orbitals contain electrons in pairs and rest three are singly occupied by electrons.( unpaired electrons )
