১০.
Which organelle is important in specialized cellular signalling?
ব্যাখ্যা
Explanations:
Cells contain a variety of organelles that perform specialized cell functions. The nucleus is an organelle that contains DNA and is the site of gene transcription. The endoplasmic reticulum and the Golgi apparatus are important in protein processing and the targeting of proteins to correct compartments within the cell. Lysosomes and peroxisomes are membranebound organelles that contribute to protein and lipid processing. Mitochondria are organelles that allow for oxidative phosphorylation in eukaryotic cells and also are important in specialized cellular signaling.

১২.
Which is the force generator for muscle cell contraction?
ব্যাখ্যা
Explanations:
There are three superfamilies of molecular motor proteins in the cell that use the energy of ATP to generate force, movement, or both. Myosin is the force generator for muscle cell contraction. Cellular myosins can also interact with the cytoskeleton (primarily thin filaments) to participate in contraction as well as movement of cell contents. Kinesins and cellular dyneins are motor proteins that primarily interact with microtubules to move cargo around the cells.

১৫.
What is the site of Ca2+ storage and release for excitation-contraction coupling?
ব্যাখ্যা
Explanations:
Sarcoplasmic reticulum (SR) is the internal tubular structure that is the site of Ca2+ storage and release for excitation-contraction coupling. It has terminal cisternae that make intimate contact with the T tubules in a triad arrangement.

১৬.
Which of the following transport processes is involved if transport of glucose from the intestinal lumen into a small intestinal cell is inhibited by abolishing the usual Na+ gradient across the cell membrane?
ব্যাখ্যা
Explanations:
In the usual Na+ gradient, the [Na+] is higher in extracellular than in intracellular fluid (maintained by the Na+–K+ pump). Two forms of transport are energized by this Na+ gradient cotransport and countertransport. Because glucose is moving in the same direction as Na+, one can conclude that it is cotransport.
