Outline four functions of proteins within the cell membrane?
There are four functions of proteins within the cell membrane. The four functions of proteins are active transport, cell recognition, cell communications, and are used as enzymes in the cell membrane.
What biological molecules are used to store energy in living organisms vary in structure and make up most of cell membrane?
ATP (adenosine triphosphate) is the primary molecule used to store energy in living organisms. Lipids, specifically phospholipids, make up most of the cell membrane structure.
What is the Difference between plasmamembrane and cell membrane?
The terms "plasma membrane" and "cell membrane" are often used interchangeably to refer to the same structure. Both terms refer to the semipermeable lipid bilayer that surrounds the cell and controls the movement of substances in and out of the cell.
What Membrane sac formed by pinching off pieces of cell membrane?
The membrane sac formed by pinching off pieces of cell membrane is called a vesicle. Vesicles are used for intracellular transport of proteins and other molecules within the cell.
What form of transport is used by the cell membrane to speed up the intake of glucose?
Facilitated diffusion is the transport process used by the cell membrane to speed up the intake of glucose. This process involves the use of protein channels or carriers to help glucose molecules pass through the membrane.
Which organic molecule is used to build the majority of the cell membrane?
Phospholipids.
What type of molecule can be used as a tunnel to move compounds across the cell membrane?
Carrier proteins are a type of molecule that can be used as a tunnel to move compounds across the cell membrane. These proteins bind to specific molecules and undergo conformational changes to transport them across the membrane. This process is known as facilitated diffusion.
What used a protein to move a molecule across a cell membrane without energy?
Facilitated diffusion uses proteins to move a molecule across the cell membrane without energy.
What molecule is used to transport oxygen and act as an enzyme and transport materials across the cell membrane and forms the filaments of muscles?
Protein.
What molecule is used to transport oxygen act as an enzyme transport materials across the cell membrane and forms the filaments of muscle?
haemoglobin
What is a molecule used by glucose as a piggyback into and out of the cell in the process of active transport?
The glucose transporter is a membrane bound protein that binds to glucose and mediates it's transport into or out of the cell.
Which type of transporters is used to move a molecule from a region of low concentration traction to a region of high concentration?
protein molecules in the cell membrane
Do nucleic acids form much of the cell membrane?
No, in fact most of the cell membrane consist of phospholipids and proteins. Integral proteins are mostly used for transport and other functions and the phospholipids which have a polar phosphate head and nonpolar lipid (fat) tails.
Which row in the chart below best the active transport of molecule X through a cell membrane?
Low concentration to high concentration; ATP is used
What happens to the pocket in the cell in the membrane when it breaks loose from the membrane?
Usually, the membrane will burst and let its contents out into the cell membrane and get used up.
What is bigger an animal cell or a molecule?
An animal cell by a trillion times over. A single molecule would be a single tail of a hydrocarbon which is used to make the lipid bilayer. This is made up of millions of phospholipids. Each has a tail and this is only the outer membrane of the cell which contains a huge amount of material.
Which row in the chart below best describes the active transport of molecule X through a cell membrane?
Low concentration to high concentration; ATP is used
