Question

the three types of active transport (0:48)
a. endocytosis, exocytosis, danceocytosis
b. phagocytosis, pinchocytosis, magocytosis
c. endocytosis, exocytosis, ion pumps (potassium and sodium)
question 4

energy in the form of what molecule is required for the sodium - potassium pump? (1:45)
atp

Explanation:

1. For the first question, active - transport mechanisms include endocytosis (taking substances into the cell), exocytosis (releasing substances out of the cell), and ion pumps like the sodium - potassium pump. Danceocytosis and magocytosis are not real biological terms, and pinchocytosis is not a recognized term for active transport in standard biology.
2. For the second question, the sodium - potassium pump is an active - transport mechanism that requires energy in the form of ATP (adenosine triphosphate) to move sodium and potassium ions against their concentration gradients.

Answer:

Question 3: C. Endocytosis, Exocytosis, Ion pumps (potassium and sodium)
Question 4: A. ATP
