Enolase is an enzyme that catalyzes one reaction in glycolysis in all organisms that carry out this process. The amino acid sequ

ence of enolase is similar but not identical in the organisms. Researchers purified enolase from Saccharomyces cerevisiae, a single-celled eukaryotic yeast that grows best at 37°C, and from Chloroflexus aurantiacus, a bacterium that grows best at the much higher temperature of 55 C. The researchers compared the activity of purified enolase from the two organisms by measuring the rate of the reaction in the presence of varying concentrations of substrate and a constant amount of each enzyme at both 37°C and 55°C.
Depending on the organism, the optimal pH for enolase to catalyze its reaction is between 6.5 and 8.0. Describe how a pH below or above this range is likely to affect enolase and its catalytic ability

Answer:

pH below or above the optimal range will result in loss of the enzyme activity.Changing the pH above or below optimum range affect the charges that reside on the amino acid molecules. Amino acids present in the active site of enzymes that attracted each other may no longer continue to be attracted.Again, the shape of the active site of the enzyme will change as a result of which substrate binding will be affected.Overall we can say that the enzymes are denatured.

Marine organisms that are euryhaline would most likely be found in which environment?
finlep [7]

Answer: Coastal estuary

Explanation:

Euryhaline animals are able to live in the wide range of salinity.These animals have the ability to live in the variety of water mostly fresh water.

The coastal estuary is one of the habitat of such animals. The green crab, molly fish are some example of the animals found in this environment.

Some of the euryhaline animals are also found in the salt and brackish water, fresh water, moderately haline et cetera.

At a location, rainwater runs off the face of a cliff that is 15 meters high. How is the face of the cliff most likely to change
natka813 [3]

The answer is;  Physical weathering by water would carve out the face of the cliff.


The bottom of the cliff would register the greatest weathering because of the force of the water hitting the rocks in the fall. As a cave is curved from the base of the cliff, the overhanging part of the cliff eventually collapses hence retracting the cliff a small distance upstream of the river. The diagram below demonstrates this;
