What else can I help you with?
What happens if a molecule is too large to go through a membrane?
The molecule will be transported across the membrane by way of a transport protein or protein channel.
Do large cells move across the cell membrane quickly?
A large cell will never move across an intact cell membrane.
What molecules will move easily across the cell membrane: large proteins, starch, water, or DNA?
Water is the molecule that will move easily across the cell membrane. It can cross the membrane through special channels called aquaporins. Large proteins, starch, and DNA are too large to pass through the membrane without assistance.
Why can oxygen diffuses across a cell membrane but Protein can not?
Its too large
What happens to the portion of the cells membrane that surround a large molecule during endocytosis?
it separates from the membrane.

How does a large particle leave a cell by a active transport?
It requires energy, and a protein carrier molecule. The large particle binds to the protein carrier on the inside of the cell. It is then transported across the membrane as a result of a conformational change in the protein (think of it flipping), and then it is released on the outside of the cell. Again, this requires some source of energy.
How large are particle accelerators?
Small particle accelerators can sit on a desktop, large circular ones can be miles across
A cell will engulf a large particle of matter that would be too large to pass through the membrane?
phagocytosis
Which one moves faster across the cell membrane the large or the small?
Small particles move faster across the membrane.

Water is the molecule that will move easily across the cell membrane. It can cross the membrane through special channels called aquaporins. Large proteins, starch, and DNA are too large to pass through the membrane without assistance.

How do large cells move across the cell membrane?
There cannot be large cells inside a cell.

it separates from the membrane.
