Which is the following is an example of compartmentation at the
intracellular level?
Group of answer choices
Skeletal muscle cells have organelles called sarcoplasmic
reticulum (SR) that contain large stores of calcium ions. The
calcium is released during muscle contraction and then pumped back
into the SR as the muscle relaxes.
The heart is divided into four chambers, with two upper chambers
that receive incoming blood and two lower, more muscular chambers
that send blood out into the circulation.
Regions of the brain are specialized for different
functions.
The walls of arteries consist of an outer connective tissue
layer, a middle layer of smooth muscle and elastic fibers, and an
inner endothelial lining.
Answer
compartmentation at the intracellular level means, inside the
cell there are various organelles like mitochondria, endoplasmic
reticulum golgi complex, each of which is a compartment and has its
own function inside the cell.
heart dividing into 4 chambers is structural feature is not
about what is happening in the cardiac cell.
the wall of arteries structure is decribed by the number of
layers of tissue present in it is not compartmentatlization inside
the cell.
skeletal muscles have sarcolemma that endoplasmic reticulum
contain calcium inside it. is an example of
compartmentalization
so, the answer is Skeletal muscle cells have organelles
called sarcoplasmic reticulum (SR) that contain large stores of
calcium ions. The calcium is released during muscle contraction and
then pumped back into the SR as the muscle relaxes.
