Ingestion of material through pinocytosis can be found in (select all that apply)
cells that line the kidney tubules
cells that line the intestinal cell walls
red blood cells
macrophages

The sodium potassium pump
requires the expenditure of energy in the form of ATP
is an example of a facilitated diffusion carrier protien
Moves sodium against its concentration gradient
Moves potassium against its concentration gradient
53.
Facilitated diffusion and active transport processes are similar in that
both require the expenditure of cellular energy for the transport to occur
require the function of membrane transport proteins
both typically refer to the transport of material along its concentration gradient
both typically refer to the transport of material against its concentration gradient
57.
Bulk transport includes
endocytosis
exocytosis

Solution
51.A,B,D(Small proteins are reabsorbed by pinocytosis, digested, and the amino acids diffuse into the blood by proximal convoluted tubule.Nutrientss are absorbed by microvilli of intestinal wall by pinocytosis. Endocytosis is used by the macrophage to engulf a pathogen.)
52.A,B,C,D(done by active transport process involving the hydrolysis of ATP to provide the necessary energy. The sodium potassium pump is an important and well understood example of active transport in which move sodium ions out of the cell and potassium ions into the cell against concentration gradient using specialised carrier protein.).
53.B(facilitated diffusion allows substances to follow the concentration gradient either way, while active transport only has substances go one way, against their concentration gradient.Active transport needs energy, while facilitated diffusion does not need energy.)
57.D(Both are two types of bulk transport;they transport ions and other substances in bulk)
