Flagella
Microtubules
Cilia
Fibrae
Actin
Microtubules
Microtubules are hollow tubes made up of polymerized tubulin that provide support throughout the cell.
Example Question #3 : Cell Biology
Which of the following characteristics are true of all enzymes?
Three of the answer choices are correct.
Enzymes are sensitive to temperature and pH.
Enzymes do not alter the equilibrium constant.
None of the answer choices are correct.
Enzymes are not used up in the reaction.
Three of the answer choices are correct.
Enzymes do not alter the equilibrium constant because enzymes are not consumed in the reaction.
Hint: Write out the equation for the equilibrium constant and notice that there is no variable for enzymes.
Enzymes are sensitive to temperature and pH, as high temperatures and very low pH can cause denaturation of an enzyme. Enzymes are only optimal at certain pH and temperature ranges.
