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.

Which body system makes red blood cells?
forsale [732]

Answer:

In the human adult, the bone marrow produces all of the red blood cells, 60–70 percent of the white cells (i.e., the granulocytes), and all of the platelets. The lymphatic tissues, particularly the thymus, the spleen, and the lymph nodes, produce the lymphocytes (comprising 20–30 percent of the white cells).

What is one effect of methane gas being released into Earth’s atmosphere? *
bogdanovich [222]

Answer:

An increase in the amount of greenhouse gases in the atmosphere

Liquid; gas

Lacking oxygen

To decrease the temperature in the compost pile

Explanation:

1.  Methane is one of the greenhouse gases. When these gases are released into the atmosphere, they increase the temperature of the earth surface because they trap heat within the earth. Other examples are carbon dioxide and water vapor.

2. Evaporation is a phase change from liquid to gas. During this process, heat is supplied to a liquid. When the molecules of the liquid gain enough energy, they then begin to break off into gaseous form. The reverse process of evaporation is condensation.

3.  Anaerobic is a process that lacks oxygen. Aerobic processes are carried out with the availability of oxygen.  

4. The reason why compost should be regularly mixed is to decrease the temperature in the compost pile. Portions of the compost can have a higher temperature than other parts. Therefore, mixing the compost will help to redistribute the heat in the compost.

What's a major assumption when drawing evolutionary relationships between organisms?
Xelga [282]

Based on DNA sequences, it is believed that changes in nucleotide sequence between two species are equivalent to the time that has elapsed since the two species diverged from their common ancestor. Gene sequencing is being used in addition to morphology to determine evolutionary relationships between organism. Homologous sequences show greater evolutionary relationship
