Which of the following cells would you expect to be engaged most heavily in bulk-phase endocytosis: (a) a B lymphocyte, (b) a pancreatic acinar cell, (c) a lung epithelial cell? Why? explain (10pts)
Homework Answers
B lymphocytes and pancreatic acinar cells are basically secretory cells that that secrete antibody and digestive enzymes respectively. And bulk phase endocytosis is the movement of particles in bulk into the cells. But a lung epithelial cell is involved in respiration where bulk amount of oxygen and carbon dioxide is exchanged with the blood. Gases first diffuse into the lung Epithelial cell then into the blood or alveoli for undergoing the process of respiration.

Cats are diploid organisms that have 38 chromosomes in their somatic cells during G1 phase. Based on this information, answer the following questions about the cell cycle of a cat's somatic cell: a) How many DNA double helix molecules are present in a somatic cell of a cat during G1 phase? Explain your answer. b) How many total DNA double helix molecules are present in a somatic cell of a cat during G2 phase? Explain your answer. c) Describe what...

1) You are studying TGF-B signaling in a line of cultured human intestinal epithelial cells by measuring the amount of collagen IV mRNA induced 10 hrs. after TGF-B addition. Normally, TGF-B causes a 5- fold increase in Col IV mRNA. a) You overexpress in this cell a mutant type II TGF-B receptor lacking its cytosolic domain (that is you express it at a level 10-fold higher than the natural (functional) receptor protein). You find that the cells no longer respond...
