There are basically three major classes of membrane lipid molecules, which are: phospholipids, cholesterol, and glycolipids.
What is cellular membrane?The cell membrane, also known as the plasma membrane, is found in all cells and serves to separate the cell's interior from the outside environment.
The cell membrane is made up of a semipermeable lipid bilayer. The cell membrane controls the transport of materials into and out of the cell.
Lipids (phospholipids and cholesterol), proteins, and carbohydrate groups attached to some of the lipids and proteins are the primary components of the plasma membrane.
Membrane lipid molecules are classified into three types: phospholipids, cholesterol, and glycolipids.
Glycerol is a three-carbon molecule that serves as the membrane lipids' backbone.
Thus, these are the three molecular components of cell membranes.

Cell organelles are specialized structures who's function is to perform various jobs inside the cell. These can be found in either prokaryotic or eukaryotic cells.
Eukaryotes are two membrane bound structure i.e. have cell wall and cell membrane. They contain organelles who are also double membraned in nature for e.g. mitochondria and nucleus.
Apart from these mitochondria and nucleus can undergo DNA replication independently due to presence of DNA . Mitochondria generate most of the chemical energy required to power the cell's biochemical reactions. And nucleus contain genetic information along with instructions required for cellular processes.

American apple cells contain an enzyme that turns the tissues brown when an apple is peeled and left for a time. Boiled apple does not go brown. Explain why the boiled apple behaves differently.
Answers
Answer:
I think I got it from recipetips.com
When cooking apples it is not as much of a concern because once they are cooked, the browning will stop. When fresh apples are peeled or cut open, the apple's cells are exposed and react with the oxygen in the air. The reaction that occurs, which is called oxidation, is what turns the apple brown.
Explanation:
Enzymes are proteins. As such they are very specific. When the apple is boiled, the enzyme becomes denatured and as such doesn't turn the apple brown.
