Describe a pathway used for the degradation of carbohydrates by strict anaerobes.?

Question

I really need help with this question.

"describe a pathway used for the degradation of carbohydrates by strict anaerobes."

thanks, really appreciate it.

Answer 1

You need to study lactic acid fermentation.

Start with this wikipedia article:

Here's a paper on it:

Answer 2

In anaerobic respiration, as the electrons from the electron donor are transported down the electron transport chain to the terminal electron acceptor, protons are translocated over the cell membrane from "inside" to "outside", establishing a concentration gradient across the membrane which temporarily stores the energy released in the chemical reactions. This potential energy is then converted into ATP by the same enzyme used during aerobic respiration, ATP synthase. Possible electron acceptors for anaerobic respiration are nitrate, nitrite, nitrous oxide, oxidised amines and nitro-compounds, fumarate, oxidised metal ions, sulfate, sulfur, sulfoxo-compounds, halogenated organic compounds, selenate, arsenate, bicarbonate or carbon dioxide (in acetogenesis and methanogenesis). All these types of anaerobic respiration are restricted to prokaryotic organisms.

Examples of anaerobic respiration

glucose + 3NO3- + 3H2O  6HCO3- + 3NH4

glucose + 3SO42- + 3H+  6HCO3- + 3SH-

glucose + 12S - 12H2O  6HCO3- + 12HS- + 18H+
