Basically, the P-P chain turns 4 protons into: 1 neutrino, 1 gamma ray, 1 positron, 1 helium nucleus.
A gamma ray = energy.
The chain converts hydrogen into helium and makes energy.
This is all occurring through fusion reactions where 2 protons basically smash into each other. But, it could also be e.g. a proton smashing with a deuterium nucleus. Or, other nuclei smashing together to make something else.
Hope this helps!
I don't understand ur question. Hmm
Answer:
In eukaryotes, thousands of chemical reactions are able to take place in separate compartments called organelles.
Explanation:
Organelles are specific cellular structures that are the means of compartmentalizing the various functions that occur within cells.
Examples of organelles and their functions are:
- <u>Nucleus</u>: contains DNA and in it occur the replication of this molecule and its transcription into RNA.
- <u>Rough endoplasmic reticulum</u>: protein synthesis and conjugation of these molecules occurs.
- <u>Mitochondrion</u>: houses all oxidative phosphorylation reactions and the electron transport chain for ATP synthesis to occur.
The organelles are then the structures that allow the development of the multiple functions that a cell has.
The other options are not correct because:
- <em><u>Bacteria</u></em><em> is a prokaryotic organism.
</em>
- <em><u>Prokaryote</u></em><em> refers to simple organisms that lack organelles.
</em>
- <em><u>Proteins</u></em><em> are biomolecules that allow the structure and function of living beings.</em>
