Which is a major difference between plant and animal cells?
Plants cells DO NOT perform cellular respiration.
Plant cells tend to have smaller vacuoles than animal cells.
Plant cells have a cell wall in addition to a plasma membrane.
Plant cells do not go through meiosis.
Which is NOT true about plasma membranes?
The plasma membrane has proteins that assist in cellular transport.
The plasma membrane is formed by phospholipids.
The plasma membrane uses active transport to pump water out of the cell.
The plasma membrane can be represented by the fluid mosaic model.
What is the name for the part of the plasma membrane represented by letter "j" in the picture?
A glycolipid.
A protein channel.
A protein pump.
An osmosis tunnel.
Which is true of both simple diffusion and osmosis?
They are systems of passive transport in which substances move with the direction of the concentration gradient.
They are systems of passive transport in which substances move against the concentration gradient.
They are systems of active transport in which substances move with the direction of the concentration gradient.
They are systems of active transport in which substances move against the concentration gradient.
How are pore proteins different than carrier proteins?
Pore proteins assist in the transportation of larger molecules than carrier proteins.
Pore proteins move substances through passive transport, but carrier proteins use energy to move substances.
Pore proteins act as hydrophylic channels that open to allow movement of substances from high concentration to low concentration.
Pore proteins change configuration to allow larger molecules to move from the outside of the cell to the inside.
Which of the following statements best describes active transport?
Active transport is a process of moving substances against the concentration gradient with the use of ATP energy.
Active transport is a process in which carrier proteins change shape to assist in the movement of large molecules in the same direction as the concentration gradient.
Active transport occurs within the lungs where gases must be quickly exchanged for cellular respiration.
All of the options describe the process of active transport.
Which is true of a sodium-potassium pump?
The sodium-potassium pump moves three sodium ions out of the cell and two potassium ions into the cell.
The sodium-potassium pump moves three sodium ions into the cell and two potassium ions out of the cell.
The sodium-potassium pump moves both sodium and potassium ions into the cell.
The sodium-potassium pump moves both sodium and potassium ions out of the cell.
This is a picture of a conentration gradient. In which direction will substances passively move across the membrane?
From left to right.
From right to left.
The substances will not move without a pump.
It's impossible to tell from this picture.
