Question

2. mitosis. 3. replication. 1) Which one of the following pathways better reflects the synthesis of a prototypical cytosolic protein? 1. Ribosome> Cytosol 2. Nucleus>Endoplasmic reticulum> Cytosol 3.) Smooth endoplasmic reticulum > Golgi apparatus>Secretory vesicle > plasma membrane> endocytic vesicle> Cytosol 4. Ribosome> Endoplasmic reticulum > Golgi apparatus> Cytosol 42) Cells lining the vas deferens (tubules transporting sperm) have a structure that helps propel sperm. This structure has a microtubule cytoskeleton. What is it and what does it do? 1 Microvilli; increase cell's surface area and absorptive ability 2. Cilia; move substances across cell surface 3. Microvilli; move substances across cell surface 4. Cilia; increase cell's surface area and absorptive ability

Explanation / Answer

1. c)

protein synthesis is integrated a function of endomembrane system including ER.golgi bodies, formation of vesicles and release frim nucleus in cystol.

2.b)

cillia that help in movement of sperm throudh ductus epididymis and vas defrence.
