At neutral pH, the ionic group COO- on succinate makes bonds with the active site of succinate dehydrogenase. This bonding is required for succinate oxidation.

<h3>What is succinate oxidation?</h3>

In the Krebs cycle , succinate dehydrogenase catalyzes the oxidation of succinate to fumarate, with the resulting electrons being supplied to respiratory chain complex III to decrease oxygen and produce water.

SDH oxidizes succinate to fumarate during the citric acid cycle. SDH is structurally similar to fumarate reductase, an enzyme that catalyzes the opposite process during anaerobic respiration in bacteria.

The activity of bacterial glutamine synthetase isI. inhibited by glutamineII. inhibited by adenylylationIII. activated by uridyl

Andreas93 [3]

Answer: Option II. inhibited by adenylylation.

Option III. activated by uridylylation of the PII subunit of adenylyltransferase.

Explanation:

Glutamine syntherase is an enzyme that is found in the mitochondria. Glutamine syntherase acts as a catalyst in the reaction that produces glutamine from glutamate and ammonia.

We think of termites as insects that “eat” wood. In fact, however, termites rely on a variety of eukaryotic and prokaryotic gut

Ivenika [448]

Answer:

Symbiosis

Explanation:

Termites are the important insects due to its role in in nutrient recycling in the terrestrial ecosystems. Termites eat wood. The wood contain cellulose, a complex carbohydrate which is cannot be digested by most insects such as termites. For the breakdown and digestion of wood is carried out by the microorganisms present in the hindgut of the termites. The microbes live in the gut as a symbiont. The microbes break down cellulose into simple sugars and fatty acids which are easily absorbed into the cells of the termites.
