C.perfringens, an obligate anaerobe, is capable of utilizing the carbohydrates release from injured tissue as an energy source.
Leto [7]

Answer;

It is a saccharolytic organism that can utilize carbohydrates anaerobically, therefore there is no evolution of co2.

Explanation;

A saccharolytic bacterium is a microbe having the ability to generate energy by metabolizing carbohydrates.

They include both heterotrophic and autotrophic organisms and transform sugars under aerobic and anaerobic conditions.

The energy-generating metabolic processes for obligate anaerobes are not coupled with the consumption of oxygen, oxygen kills the organisms.

The chemical mechanisms used to avoid errors in protein synthesis are different from those used during DNA replication. DNA poly
Savatey [412]

Answer:

(C) Aminoacyl-tRNA synthetases have an additional active site that binds to non-cognate tRNAs. The tRNAs that bind to this second active are hydrolyzed and released from the enzyme.

Explanation:

In case of translation, proof reading is done by aminoacyl-tRNA synthetases only. Aminoacyl-tRNA synthetases have two mechanisms to avoid error during translation which are mentioned as under:

<u>(1) Chemical proof reading:</u> Incorrect amino acids rather than being hydrolyzed in catalytic pocket get hydrolyzed in editing pocket and thus they hardly get attached to tRNA.  

For example: For distinguishing similar amino acids like isoleucine and valine, isoleucyl-tRNA synthetase uses a second active site which is meant for only valine not for isoleucine. In this particular site, valine which had entered the enzyme is cleaved away with the help of editing reaction after which the enzyme is well prepared to process isoleucine which is the correct amino acid for this enzyme.

<u>(2) Kinetic proof reading: </u>Even if an incorrect amino acid has entered a particular aminoacyl-tRNA synthetase, it does not cause appropriate conformational change in the enzyme because of which the incorrect amino acid loosens from the enzyme and does not get incorporated.

Note: In this example, only chemical proof reading is mentioned not kinetic proof reading.
