What is the process the does not require oxygen? Electron Transport Chain
Fermentation
Krebs Cycle
None of the above, they all need oxygen

Fermentation is an alternative route for obtaining energy, in the absence of oxygen. Fermentation is the process that does not require oxygen.

Fermentation:

It is an alternative route for obtaining energy, in the absence of oxygen. In anaerobic respiration, the electron acceptor of NADH is an organic compound.

It has a low energy yield at the end of the process.

The electron transport chain and the Krebs cycle are the processes that occur in the presence of oxygen.

Therefore, Fermentation is the process that does not require oxygen.

The process that does not require oxygen is fermentation.

Explanation:

Fermentation is an alternative route of cellular respiration for obtaining energy, in the absence of oxygen. In aerobic respiration, oxygen is the acceptor of electrons from NADH but, in anaerobic respiration, the electron acceptor is an organic compound.

The fermentation process does not occur in the mitochondria nor does it involve the electron transport chain, and has a low energy yield at the end of the process.

With respect to the other options:

a. seed plant structure. 1. the three main plant organs are roots, stems, and leaves. a fourth kind of tissue, meristematic tissue, is responsible for plant growth. meristematic tissue is the only plant tissue that produces new cells by mitosis. plants can lose water out of their leaves as they exchange gases with the air

explanation:

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
