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. Identify the appropriate negative control the researchers most likely used when measuring the reaction rate in the presence of each organism’s enolase.
The extracted lipids covered twice the surface area of the intact red blood cells.
Explanation:
In 1925 two dutch scientist performed this experiment and they come to know that the basic structure of the membrane is phospholipid bilayer which serves as a stable separator between the two sections. Thats why the lipids they had extracted was covered twice the surface area of the intact red blood cells.
Telophase is the fifth step in mitosis. In telophase, chromosomes arrive at opposite poles and begin to decondenese. nuclear envelope material surrounds each set of chromosomes.
