The electron transport chain is named for Select one: a. the removal of unnecessary electrons from the cell b. the conversion of
Colt1911 [192]

Answer:

The correct answer is e. the passage of electrons from one energy-generating carrier to another

Explanation:

The electron transport chain is a series of proteins and organic molecules found in the inner membrane of the mitochondria. Electrons pass from one member of the transport chain to the next in a series of redox reactions. The energy released in these reactions is captured as a proton gradient, which in turn is used to form ATP in a process called chemosmosis.

These transport molecules, in the inner mitochondrial membrane, are reduced and oxidized, accepting electrons and transferring them to the next molecule, electrons descending from high energy levels to lower ones, that is, from one energy-generating carrier to another. When lowering to other levels, energy is released that will be used in the synthesis of ATP by oxidative phosphorylation.

VikaD [51]

Answer:

1. You will be unable to smell

3. Your olfactory receptor cells will no longer be able to respond  to molecules trapped in the mucus.

Explanation:

The Olfactory receptors are the receptors present in the olfactory neurons which detect different odorants or smell.

The olfactory receptors are embedded in the epithelium or mucous lining of the nose in which one extension of the cell body reaches the epithelium surface and branches into cilia like structures which sense the odour.

If the axons of the olfactory cells are broken then the cells will not be able to respond to the molecules trapped in the mucus and thus no detection of odour. The signal will not be generated in response and thus will not be sent to the brain. Thus, the person will not be able to smell.

Thus, Options-1 and 3 are correct.
