Explain what freeze-fracture techniques reveal about the arrangement of proteins in membranes?
Freeze-fracture techniques reveal the organization of proteins in membranes by freezing a specimen and then fracturing it to expose the internal structure. This technique allows for visualization of the arrangement of proteins within the lipid bilayer, showing whether they are randomly distributed or organized into specific patterns or clusters. It provides insights into the spatial organization and interactions of proteins within the membrane.

Does biological molecules proteins and lipids have cell membranes?
Proteins and lipids don't have cell membranes but are the molecules that make up the bulk of what a cell membrane is.
Which would enable you to study the membranes of a chloroplast?
To study the membranes of a chloroplast, you could use techniques such as electron microscopy to visualize the membranes at a high resolution, biochemical fractionation to isolate and analyze the different membrane components, and functional assays to study the activities of specific membrane proteins.
Each lymphocyte has thousands of receptor proteins in its membranes. What is the job of these receptor proteins?
To recognize antigens.

To recognize antigens.
What kinds of proteins can be found in cell membranes?
Proteins found in cell membranes can include transport proteins, receptor proteins, cell adhesion proteins, and enzymes. These proteins play crucial roles in maintaining the structure and function of the cell membrane, as well as facilitating various biological processes such as cell signaling, molecule transport, and cell-cell interactions.
Freeze etch techniques purpose method?
A technique used to look at membranes that reveal the pattern of integral membrane proteins.
When was Orientations of Proteins in Membranes database created?
Orientations of Proteins in Membranes database was created in 2005.
Why Proteins do not pass through cell membranes?
Hydrophilic proteins.
How would you describe the freeze etch techniques?
A technique used to look at membranes that reveal the pattern of integral membrane proteins. Cells are quickly frozen in liquid nitrogen.
What Flattened membranes that package proteins?
this is a cell

What is the cell membranes channels and pumps made of?
Proteins.
What are cell membranes built around?
Lipids and Proteins.
What macromolecule makes up cell membranes?
Proteins!
What is the system of membranes in the cytoplasm where proteins are made?
chlororplasts
How are proteins used in biological membranes?
there are protein channels in the membranes and it regulate the entry of the molecules of different size.
