What are the basic structural molecules of the cell membrane?
A plasma membrane’s principal components are lipids (phospholipids and cholesterol), proteins, and carbohydrates attached to some of the lipids and proteins. A phospholipid is a molecule consisting of glycerol, two fatty acids, and a phosphate-linked head group.
What are the 4 basic parts of a cell structure?
Four Common Parts of a Cell. Although cells are diverse, all cells have certain parts in common. The parts include a plasma membrane, cytoplasm, ribosomes, and DNA.
What provides structure for the cell?
The part of a cell that provides structural support and protection is the cell wall.
Which of the following types of molecules are the major structural components of the cell membrane?
Phospholipids
Phospholipids are the major structural components of most membranes. These molecules form a bi-layer (a double-layer of material) on the surface of the cell with their long, hydrophobic hydrocarbon chains pointing inward to the center of the bi-layer and their hydrophilic phosphate groups facing outwards.
What are the basic organelles of a cell?
Organelles in animal cells include the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, vesicles, and vacuoles. Ribosomes are not enclosed within a membrane but are still commonly referred to as organelles in eukaryotic cells.
Which organelle provides structure and support for the cell?
The cytoskeleton
The cytoskeleton, a network of fibers that supports the cell and gives it shape, is also part of the cytoplasm and helps to organize cellular components.
Which of the following types of molecules are the major structural?
Which of the following types of molecules are the major structural components of the cell membrane? The answer is C) Phospholipids and proteins.
What is the structure of a biological molecule?
The structure of biological molecules. Cells are largely composed of compounds that contain carbon. The study of how carbon atoms interact with other atoms in molecular compounds forms the basis of the field of organic chemistry and plays a large role in understanding the basic functions of cells.
What makes up the structure of a cell?
Cell Structure. It includes features from all cell types. A cell consists of three parts: the cell membrane, the nucleus, and, between the two, the cytoplasm. Within the cytoplasm lie intricate arrangements of fine fibers and hundreds or even thousands of miniscule but distinct structures called organelles.
What kind of molecules are found in cells?
It is, however, the organic molecules that are the unique constituents of cells. Most of these organic compounds belong to one of four classes of molecules: carbohydrates, lipids, proteins, and nucleic acids.
How are proteins formed in a biological cell?
The structure of biological molecules. In theory, nearly an infinite variety of proteins can be formed, each with a different sequence of amino acids. However, nearly all these proteins would fail to fold in the unique ways required to form efficient functional surfaces and would therefore be useless to the cell.
