It's a mixture of protein and lipids

Some carbohydrates are anchored and some are free floating

Some proteins are anchored and some are free floating

It provides and anchor for the cellular cytoskeleton

What is the double layered structure of the plasma membrane called?

The water mosaic model

The fluid ark model

The fluid mosaic model

What are the two main categories of proteins in the plasma membrane?

Which of the below applies to peripheral proteins?

They form covalent bonds with integral proteins

They do not allow anchoring of other molecules etc

They define cell shape, polarity and strength

They are amphipathic

They are hydrophobic

Which of the below applies to integral proteins?

They are amphipathic

They act as receptors

They do not allow anything to transport across the membrane

They transport things across the membrane

They act as enzymes

What is simple diffusion?

Substance moves across the lipid bilayer without the help of membrane transport proteins

Substances move across the lipid bilayer with the help of a non-specific membrane transport protein

Water is able to cross the lipid bilayer by using either simple diffusion or channels known as aquaporins

What is Non-specific facilitated diffusion?

Water is able to cross the lipid bilayer by using either simple diffusion or channels known as aquaporins

Substance moves across the lipid bilayer without the help of membrane transport proteins

Substances move across the lipid bilayer with the help of a non-specific membrane transport protein

What is specific facilitated diffusion?

Substance moves across the lipid bilayer without the help of membrane transport proteins

Water is able to cross the lipid bilayer by using either simple diffusion or channels known as aquaporins

Substances move across the lipid bilayer with the help of a membrane transport protein specific to a particular substance

What is facilitated diffusion with water?

Water is able to cross the lipid bilayer by using either simple diffusion or channels known as aquaporins

Substance moves across the lipid bilayer without the help of membrane transport proteins

Substances move across the lipid bilayer with the help of a membrane transport protein specific to a particular substance

What is a uniport?

Allows the transport of one solute at a time either using a dedicated channel or carrier protein using ATP

Allows the transport of one solute at a time either using a dedicated channel or carrier protein without ATP

What is primary active transport?

Transporter protein couples the movement of an ion (commonly H+ or Na+) down its electrochemical gradient to the uphill movement of another solute against a concentration gradient

Uses energy in the form of ATP to transport solute across the membrane usually against a concentration gradient I.e moving from a high to low concentration

Allows the transport of one solute at a time either using a dedicated channel or carrier protein using ATP

What is secondary active transport?

Substance moves across the lipid bilayer without the help of membrane transport proteins

Uses energy in the form of ATP to transport solute across the membrane usually against a concentration gradient I.e moving from a high to low concentration

Transporter protein couples the movement of an ion (commonly H+ or Na+) down its electrochemical gradient to the uphill movement of another solute against a concentration gradient

What is a symport? Think sausage and mash

Allows the transport of one solute at a time either using a dedicated channel or carrier protein without ATP

Transports the solute and co-transported at the same time in the same direction and typically against a concentration gradient

Transports the solute in or out and the co-transported in the opposite direction I.e one in, one out. It will generally move down its electrochemical gradient

What is an anti-port? Think pretty girls at the club

Transports the solute in or out and the co-transported in the opposite direction I.e one in, one out. It will generally move down its electrochemical gradient

Transports the solute and co-transported at the same time in the same direction and typically against a concentration gradient

Allows the transport of one solute at a time either using a dedicated channel or carrier protein without ATP
