Question 1

Question
The main difference between active and passive transport is that active transport requires [blank_start]ATP[blank_end] and passive transport uses [blank_start]kinetic[blank_end] [blank_start]energy[blank_end].
Answer
  • ATP
  • kinetic
  • energy

Question 2

Question
Which of the following substances cross the plasma membrane by passive transport? Check all that apply.
Answer
  • Carbon Dioxide
  • Oxygen
  • Water
  • Steroid Hormones
  • Peptide Hormones
  • Potassium Ions
  • Glucose

Question 3

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

Question 4

Question
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.
Answer
  • True
  • False

Question 5

Question
Osmosis is another word for diffusion.
Answer
  • True
  • False

Question 6

Question
Instead of talking about "water concentration", we normally refer to "[blank_start]water[blank_end] [blank_start]potential[blank_end]", which is the [blank_start]tendency[blank_end] of water molecules to [blank_start]diffuse[blank_end] from one [blank_start]region[blank_end] to another. Pure water has a water potential of (in digits) [blank_start]0[blank_end].
Answer
  • water
  • potential
  • tendency
  • diffuse
  • region
  • 0

Question 7

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

Question 8

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

Question 9

Question
Which of the following molecules are transport by bulk transport?
Answer
  • Exocytosis and endocytosis
  • Large proteins
  • Glucose
  • Other organisms
  • Oxygen
  • Sodium ions

Question 10

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

Question 11

Question
Why is ATP needed for active transport and bulk transport? Check all that apply.
Answer
  • Moving substances against concentration gradient
  • Synthesising enzymes involved in bioluminescence
  • Movement of cytoplasm and plasma membranes
  • Vesicle formation
  • Antigen presentation
  • Dissolution of large proteins
