Chapter 4, Problem 1S
The smooth endoplasmic reticulum is the site of synthesis of the phospholipids that make up all the membranes of a cell—especially the plasma membrane. Use the diagram of an animal cell (figure 4.6) to trace a pathway that would carry a phospholipid molecule https://bookshelf.textbooks.com/#/books/9781259668920/cfvi/6/30!/4/2/2@0:0 67/68

Ammonia (NH3) is a weak base that under acidic conditions becomes protonated to the ammonium ion in the following reaction:
NH3 + H+ → NH+4
NH3 freely permeates biological membranes, including those of lysosomes. The lysosome is a subcellular organelle with a pH of about 4.5–5.0; the pH of cytoplasm is about 7.0. What is the effect on the pH of the fluid content of lyso- somes when cells are exposed to ammonia? Note: Ammo- nium (NH4+) does not diffuse freely across membranes.
A certain eukaryotic cell type specializes in synthesizing lipids. Which organelle would be
found in greater abundance in this cell type than in other cell types that don't synthesize
lipids?
Mitochondria
Smooth endoplasmic reticulum
Rough endoplasmic reticulum
Lysosomes
Endoplasmic reticulum, mitochondria, and golgi bodies are structures in cell whose forms dictate their physical functions. Describe their function in relation to their structure.
