This structure includes all the fluid and organelles contained within the cell membrane.
This structure is designed to construct new proteins from amino acids.
This structure has a double membrane and contains the DNA of the cell.
Which of the following correctly describes the golgi body?
Flattened stack of membranes that package proteins for exocytosis
Membranes that allow for the transport and creation of new proteins
Double-membrane structure with pores to allow transport in and out
Double-membrane structure with one internal folded membrane for energy production
Which structure allows for the movement of particles across the surface of the cell?
Some cells contain other structures, like haemoglobin (a protein that can store oxygen molecules) or pigments like melanin. State whether these would be considered part of the cytoplasm and explain your answer.
This structure is a phospholipid. Which of the following most accurately describes part B of the structure?
What is the name of the model used to describe the nature of the cell membrane?
cell membrane transport
The concentration of glucose outside of Cell A is 8mmol/L. The concentration of glucose inside of Cell A is 16mmol/L. Glucose is currently entering the cell. This is a form of _______________________ transport.
Which of the following is not a function of the cell membrane?
A large protein must exit the cell membrane. There is a higher concentration of this large protein inside the cell than outside the cell. This protein will leave the cell using ___________________.
Which of the following forms of membrane transport is used by oxygen?
The membrane of Cell B allows iodine to pass through but does not allow starch to pass through. This is an example of a _________________ membrane.
A channel and carrier protein are different to one another because
carrier proteins are two directional while channel proteins are one directional
carrier proteins allow for passive transport while channel proteins allow for active transport
channel proteins are involved in cell membrane transport while carrier proteins are not
channel proteins are specific and carrier proteins are non-specific
Which form of membrane transport is this?
What type of tissue is this?
Glucose is an example of a

At least 10 saccharides
At least 100 saccharides
At least 10 amino acids
At least 100 amino acids
Explain the relationship between surface area and volume in terms of cell membrane transport efficiency.
