What kinds of proteins can be found in cell membranes?

There are two kinds of proteins in a cell membrane: peripheral PROTEINS OR trans membrane proteins. Cell membranes are able to perform various functions only because of different membrane protein functions. Most of the membrane proteins have alpha helix structure.


If a cell lacked ribosomes it wouldn't be able to do what?

It wouldn't be able to synthesize proteins.


How is virus like a cell?

A virus is not similar to a cell, although it requires a host cell to reproduce. The only thing in common that a virus has to a cell is it has DNA.


WHY is it important for a cell to be able to build proteins properly?

The proteins must be built properly so they will function properly, which is essential for the cell to be able to function properly.


Why transport proteins require energy to function in active transport?

Because there is a higher concentration inside the cell then out side ....because it requires energy to move the molecules outside in a different direction then they would normally move, it is like riding a bike up a hill it requires energy.


What will happen if ribosomes are remove from the cell?

The cell will not be able to make proteins, it will not function and will die.

Would a cell be able to live without lysosomes?

No, the cell would not be able to digest and break down proteins and the cell would not get enough energy to function properly.


What requires the use of the energy and the help of transport proteins to move a molecule across a cell membrane?
