Glucose transport in in the interstitial epithelium (from the
lumen or cavity to enterocyte) via the SGLTI.
Select one: A. Is an example of simple diffusion because glucose moves from
high concentration in the lumens to low concentration in the
enterocyte. B. Is an example of secondary active transport because glucose
uses the sodium of gradient. C. Is an example of facilitated passive transport because
glucose moves from high concentration in the lumen to low
concentration in the enterocyte. D. Is an example of primary active transport that uses a glucose
and ATP hydrolysis.

vesicles for storage. Neurotransmitter use a antipode exchanger
protein that is proton dependent.

Answer:
1. B. The Na+ -K+ pump is an example of secondary active
transport.
Explanation: Na+ -K+ pump is an example of primary active
transport that utilizes the energy from the breakdown of the ATP.
Secondary active transport utilizes the enrgy coming from the
trasnport of the molecules down the concentration gradient.
2. False
Explanation: Glucose transport across the cell occurs both down
their concentration gradient through facilitated transport and
against their concentration gradient via secondary active
transport.
3. B. Is an example of secondary active transport because
glucose uses the sodium of gradient.
Explanation:
Primary active transport is the transport of molecules against
their concentration gradients via transport protein utilising the
energy directly from the ATP breakdown.
Sodium ion is moving against concentration gradient using Na K
ATPase pump. This is primary active transport of sodium. As a
result, Large sodium concentration gradient is developed across the
cell. This in turn causes facilitated diffusion of sodium along the
concentration gradient across the cell from another carrier
protein. When sodium is moving passively across the cell, it moves
the glucose along with it using the energy released by passive
movement of sodium. Such transport of ions using energy coming
indirectly from the transport of other ion is called secondary
active transport.
