Put the following events of phagocytosis in order of occurrence.   [BLANK-1] Lysosomal enzymes digest the particles, leaving a residual body. [BLANK-2] Phagocyte adheres to pathogens or debris. [BLANK-3] Lysosome fuses with the phagocytic vesicle, forming a phagolysosome.   [BLANK-4] Exocytosis of the vesicle removes indigestible and residual material. [BLANK-5] Phagocyte forms pseudopods that eventually engulf the particles, forming a phagosome.

Please put these events in the order of occurrence for the renin-angiotensin-aldosterone mechanism (indirect renal mechanism).   [BLANK-1]  Angiotensin converting enzyme (ACE) converts angiotensin I to angiotensin II   [BLANK-2]  ↓ Arterial bp → release of renin (from kidneys)  [BLANK-3]  Renin catalyzes conversion of angiotensinogen to angiotensin I

What is the name of the voltage maintained by the cell before an action potential occurs?

In lecture, we covered a toxin that is associated with the Puffer fish. That toxin, called TTX, is fatal. How does it interfere with the action potential? Why is it fatal?

Which of the following is most accurate regarding propagation?

Which of the following statements is most accurate regarding hyperpolarization?

Which of the following is most accurate regarding multiple sclerosis (MS)?

Which of the following is most accurate regarding sodium’s movement across the cell membrane?

An axon is _______________ when the inside of the cell becomes more positive, and it is ______________ when the inside of the cell becomes more negative than it was at rest.

As explained in lecture, what is the primary importance/purpose of the threshold of excitation? (The correct answer is not, “it starts the action potential”. There is a more specific answer.)
