Question

A strict anaerobe can gain its energy from:

Chemolithotropy

anaerobic respiration

glycolysis

fermentation

all are correct

Answer 1

Option E-All are correct.

A Strict Anaerobe are Organsims That cannot Survive in the presence of Oxygen.So they Requires Anaerobic Methods to Obtain energy.

Anaerobic Method to Obtain Energy can Include-Chemolithotropy,anaerobic respiration,glycolysis,fermentation.

*Chemolithotrophy:This is the Process by which energy is obtained from inorganic molecules like Iron,Sulphate.

The Best chemolithotrophs are aerobic respirers.But There are Anearobic Organisms that are capable of Obtaining energy From Inorganic Compounds.

*Glycolysis is the Process by which Glucose is Converted to 2 Molecules of Pyruvate.This Process donot Require Energy.

But Aerobic Organisms take This Pyruvate into Mitochondria for Aerobic Respiration.

In Anaerobic Organism Pyruvate Undergo Fermentation.

*Fermentation:Fermentation is the anaerobic process used by Aneorobic Organisms for energy.

Anaerobic Organism Converts the Pyruvate formed by Glycolyisis-----Products like Lactate for energy
