Cell transport Review Level 2

The arrows in the diagram above represent the movement of materials. This movement of materials indicated by the arrows is most directly involved in the processes of-

• respiration and replication

• photosynthesis and excretion

• digestion and recycling

• circulation and coordination

The diagram below represents events associated with a biochemical process that occurs in some organisms. Which statement concerning this process is correct?

• The process represented is respiration and the primary source of energy for the process is the sun.

• The process represented is photosynthesis and the primary source of energy for the process is the sun.

• This process converts energy in organic compounds into solar energy which is released into the atmosphere.

• This process uses solar energy to convert oxygen into carbon dioxide.

An investigation was carried out and the results are shown below. Substance X resulted from a metabolic process that produces ATP in yeast (a single-celled fungus).

Which statement best describes substance X?

• It is oxygen released by protein synthesis.

• It is glucose that was produced in photosynthesis.

• It is starch that was produced during digestion.

• It is carbon dioxide released by respiration.

Which of these is a characteristic of photosynthesis that distinguishes it from cellular respiration?

• Photosynthesis produces a form of light energy

• Photosynthesis is carried out in biochemical pathways

• Photosynthesis is able to make large amounts of ATP

• Photosynthesis includes a chemical cycle that uses CO2 as a reactant.

The difference between osmosis and active transport is that-

• active transport moves molecules in animal cells, osmosis

  moves molecules in plants.

• Osmosis requires energy to move water up a concentration gradient, active transport does not.

• Active transport requires energy to move molecules up a concentration gradient, osmosis does not.

• Active transport can only move specific particles across a membrane, osmosis can move any particle.

Which of the following scenarios represents an example of facilitated diffusion?

• Blood vessels transport glucose to cells through channel proteins in the cell membrane.

• CO2 waste from cell respiration passes directly through the cell

  membrane.

• Limp celery becomes crisp as water moves into its cells.

• Sweating lowers body temperature as water is evaporated off the skin.

Goldfish, like other freshwater fish, have salt concentrations in their cells that are close to the salt concentration of the freshwater around them, enabling them to maintain homeostasis easily in their freshwater environment. Why is it critical that you never put a freshwater fish in a saltwater aquarium tank?

• The fish will die as its cells swell due to water moving into them.

• The fish will die because it will not be able to pass the water through its gills.

• The fish will not be affected, as there will be no net movement of water.

• The fish will die as its cells shrivel due to water leaving them and moving towards the saltwater.
