Question

Cell membranes have ______electron_________ ________carrier___________ that act like carriers making it easy for certain molecules to pass through.
An example of this is glucose. Glucose can pass through a ________membrane___________ ______________________ and it can move in either direction. This is sometimes known as a _________________________ _________simple____________ diffusion.
Since this is still considered diffusion, the movement of the molecules will still only occur if there is a _______________ concentration of the particular molecules on one side than the other. This movement does _________ require energy.
Sometimes cell materials must move in the opposite direction, _________________ the concentration gradient. This is known as _______________________ __________________. This type of movement _____________________ energy. Typically this involves _____________________ molecules.
Large molecules or even solid materials can be transported by the cell membrane. _____________________________ is the process of taking material into the cell by the means of infolding or pockets. Large molecules, clumps of _______________, or when whole cells can be taken up this way.
In ___________________________ it means “cell eating”. The material is engulfed and takes a considerable amount of energy.
In a similar process known as _______________________, the cell will take in liquid and pinch off to form vacuoles within a cell.
Many cells also release large amounts of material from the cell, a process which is called ________________________.
What is the difference between phagocytosis and pinocytosis?
What is the main way active transport differs from diffusion?
What is the relationship between active transport and homeostasis?
