Which structure lies inside the cell wall and encloses the cytoplasm of the cell?
Plasma (cytoplasmic) membrane
What is the main function of the plasma membrane related to ATP production?
Mediates oxidative phosphorylation for ATP production
Which type of proteins in the plasma membrane contain channels through which substances enter and exit the cell?
Integral proteins
Why do large molecules such as proteins usually not pass through the plasma membrane?
Possibly because these molecules are larger than the channels in integral proteins
What type of molecules usually pass easily through the plasma membrane?
Water, oxygen, carbon dioxide, and some simple sugars
What is the main function of peripheral proteins in the plasma membrane?
Functioning as enzymes or mediators of changes in membrane shape during movement
Which process involves the movement of molecules or ions from an area of high concentration to an area of low concentration until they are evenly distributed?
Facilitated Diffusion
What is the net movement of solvent molecules across a selectively permeable membrane to restore equilibrium in osmotic pressure?
Osmosis
Which process requires energy (ATP) to move substances against the concentration gradient?
Active Transport
