Answer:
Just 1 that's why it is asexual and not sexual.
Explanation:

<h2>Fixation</h2>
Nitrogen in its gaseous form (N2) can’t be used by most living things. It has to be converted or ‘fixed’ to a more usable form through a process called fixation. There are three ways nitrogen can be fixed to be useful for living things:
<h3>Biologically: </h3>
Nitrogen gas (N2) diffuses into the soil from the atmosphere, and species of bacteria convert this nitrogen to ammonium ions (NH4+), which can be used by plants. Legumes (such as clover and lupins) are often grown by farmers because they have nodules on their roots that contain nitrogen-fixing bacteria.
<h3>Through lightning: </h3>
Lightning converts atmospheric nitrogen into ammonia and nitrate (NO3) that enter soil with rainfall.

Oxidative phosphorylation requires a proton gradient.
- Cells use enzymes to oxidize foods in the metabolic pathway known as oxidative phosphorylation, electron transport-linked phosphorylation, or terminal oxidation, which releases chemical energy to create adenosine triphosphate.
- This happens inside mitochondria in eukaryotes. The majority of the energy required for biosynthesis, maintaining a healthy ion balance, and mechanical effort is provided by oxidative phosphorylation, which is the principal source of ATP in higher animals.
- A succession of proteins and electron carriers in the mitochondrial membrane, as well as the electron transport chain, are all involved in the process of oxidative phosphorylation.
