Select from the dropdown lists to complete the text.

Diffusion is a form of ( passive, active ) transport, requiring no ( ATP, energy, heat, concentration gradient ). It involves the movement of molecules from an area of ( high, low ) concentration, across a ( partially permeable, permeable, biological ) membrane, to an area of ( low, high ) concentration. In other words, ( down, up ) the ( concentration gradient, concentration, concentration amount, membrane ). The rate of diffusion depends on factors such as ( size, shape, energy content ) of molecule, ( steepness, presence, diffusion ) of concentration gradient, ( temperature, pH, light intensity ), surface area, and diffusion ( distance, barrier, membrane ).

Explanation

Question 4 of 11

1

When transport requires no ATP, involves movement down a concentration gradient, and requires the aid of a transmembrane protein which changes conformation, this is a form of passive transport.

Select one of the following:

  • True
  • False

Explanation

Question 5 of 11

1

  • True
  • False

Instead of talking about "water concentration", we normally refer to " ", which is the of water molecules to from one to another. Pure water has a water potential of (in digits) .

Water moves in and out of cells by ( osmosis, facilitated diffusion, active transport, co-transporters ). A plant cell with lots of water in it is ( turgid, cytolysed, plasmolysed, crenated ), while ( cytolysis, crenation, plasmolysis, flaccidity ) can be caused by too much water inside an animal cell. ( Plasmolysis, Cytolysis, Excess alkalinity, Crenation ) occurs in plant cells when there is a ( low, high ) water potential in the cell and the cell membrane is ( drawn inwards, burst, damaged, irreversibly stretched ). ( Crenation, Osmosis, Cytolysis, Plasmolysis ) describes the shrinking of an animal cell with ( low, high ) internal water potential.

Explanation

Question 8 of 11

1

Which of the following statements are TRUE about active transport? Check all that apply.

Select one or more of the following:

  • Requires energy in the form of ATP.

  • Substance moves down concentration gradient.

  • Requires carrier proteins.

  • Heavily relied on my neurones to maintain resting cell potential.

  • Often used with inorganic ions.

Explanation

Question 9 of 11

1

Which of the following molecules are transport by bulk transport?

Select one or more of the following:

  • Exocytosis and endocytosis

  • Large proteins

  • Glucose

  • Other organisms

  • Oxygen

  • Sodium ions

Explanation

Question 10 of 11

1

Select from the dropdown lists to complete the text.

Phagocytosis describes a process where a cell ( ingests, digests, expels, synthesises ) a foreign particle, usually one that is quite ( large, small ). First, the cell changes shape and ( engulfs, concentrates, vesiculates ) the foreign particle. Then, parts of the cell surface membrane at the extremes ( fuse together, separate, open up ) and form a ( vesicle, lytic enzyme, phagocyte ) around the foreign particle. Cells capable of this process are ( phagocytic, exocytic, white blood cells, red blood cells ). This is ( an active, a passive ) process.

Explanation

Question 11 of 11

1

Why is ATP needed for active transport and bulk transport? Check all that apply.

Select one or more of the following:

  • Moving substances against concentration gradient

  • Synthesising enzymes involved in bioluminescence

  • Movement of cytoplasm and plasma membranes

  • Vesicle formation

  • Antigen presentation

  • Dissolution of large proteins
