Explanation:
Actually, two organelles transport protein in a eukaryotic cell (multicellular organisms): (rough) Endoplasmic Recticulum and Golgi Apparatus.
The (rough) endoplasmic recticulum transport the newly synthesized proteins to the golgi apparatus from where they are transported to the various regions of the cell or outside the cell. Smooth endoplasmic recticulum is not associated with protein transport.
Proteins, carrying a signaling sequence, are transported from the endoplasmic recticulum, packaged into vesicles, to the golgi apparatus (or golgi complex or golgi bodies). These proteins are modified by enzymatic reactions as they move through the golgi apparatus. After processing, these proteins are either excreted from the cell or are sent to various locations within the cell.
It is difficult to pinpoint the location of these organelles within the cell as locations are different for mammals, plants, yeasts, etc. Generally, the golgi apparatus is found adjacent to the endoplasmic recticulum, which in turn is found throughout the cell but has a higher density near the nucleus.
Options are not provided in the question. The complete question is as following:
The reabsorption of glucose occurs primarily through the walls of the
A. glomerular capsule.
B. nephron loop.
C. proximal convoluted tubule.
D. distal convoluted tubule.
E. renal duct.
Answer:
C. proximal convoluted tubule.
Explanation:
Reabposrtion of glucose is supported by the nephron present in the kidney which mainatain body fluid homeostasis. It maintains extracellular body fluid volume stable and also maintains the minerals and salts which are essential for body functioning. So, glucose reabsorption is a part of homeostasis.
The process of glucose reabsorption primarily starts through the walls of the proximal convoluted tubule. proximal convoluted tubule are covered in microvillii and are extensive in length which increases the surface area for absorption. it also contain densly packed mitochndria which provide energy for efficient reabsorption. and then they are tranposrted to proximal straight tuble fo rfurther filteration.
Hence, the correct otpion is C.
