What else can I help you with?
What support the axon from within?
The axon is supported from within by microtubules, which are part of the cytoskeleton. Microtubules provide structural support and help in the transport of molecules and organelles along the length of the axon.
What are some of the functions of these proteins and other molecules?
Proteins can have functions such as enzyme activity, structural support, signaling, transport, and defense. Other molecules like lipids can serve as energy storage, cell membrane components, and signaling molecules. Carbohydrates can function as a source of energy or as structural components in cells.
What molecule is made by joining amino acid subunits in long chains which provide a wide variety of functions in cells?
Proteins are molecules made by joining amino acid subunits in long chains. Proteins play a wide variety of functions in cells, including structural support, enzyme catalysis, signaling, and transport.
Is cellulose an important structural molecule in plants?
Yes, cellulose is a major component of plant cell walls, providing structural support and rigidity to plant cells. It is a long chain of glucose molecules that form microfibrils, giving strength to the cell wall and allowing plants to grow upright.
What is buried in these layers of lipids in the cell membrane?
Proteins, cholesterol, and other molecules are embedded within the layers of lipids in the cell membrane. These components play various roles in cell signaling, transport, and structural support.

What shape of a protein molecule resembles?
Protein molecules can have various shapes, such as globular, fibrous, or membrane-bound. The shape of a protein is important for its function, with globular proteins often being enzymes or transport molecules, and fibrous proteins providing structural support. Additionally, the shape of a protein is determined by its specific sequence of amino acids.
The name of a very strong structural molecule in plants that is formed by hydrogen bonding between chains of glucose molecules?
Cellulose is a very strong structural molecule in plants that is formed by hydrogen bonding between chains of glucose molecules. It provides support and rigidity to plant cell walls, allowing them to maintain their shape and structure.
What molecule is made by joining amino acid subunits in long chains which provide a wide variety of functions in cells?
Proteins are molecules made by joining amino acid subunits in long chains. Proteins play a wide variety of functions in cells, including structural support, enzyme catalysis, signaling, and transport.
What is a membrane protein and how does it function within the cell membrane?
A membrane protein is a type of protein that is embedded within the cell membrane. It functions by helping to transport molecules in and out of the cell, acting as receptors for signaling molecules, and providing structural support to the cell membrane.
What role does protein play in the functioning of a cell?
Proteins are essential molecules that perform various functions in a cell, such as structural support, enzymatic reactions, cell signaling, and transport of molecules. They are involved in nearly every aspect of cellular function and are crucial for the proper functioning of a cell.

Proteins, cholesterol, and other molecules are embedded within the layers of lipids in the cell membrane. These components play various roles in cell signaling, transport, and structural support.
Without a cytoskeleton eukaryotic cells would not?
Without a cytoskeleton, eukaryotic cells would not be able to maintain their shape, divide, transport molecules within the cell, or move. The cytoskeleton provides structural support and helps to organize cellular components.
What proteins are embedded in the plasma membrane?
They are called integral proteins
What types of things do proteins do in cells?
Proteins perform a multitude of tasks in cells including acting as structural support, catalysis of chemical reactions (enzymes), molecule and ion transport, cell signaling, regulation of the cell cycle and several other important functions.
