Active Transport Matching Activity

The diagram below represents the process of active transport. In the table below, drag each term as it applies to active transport and match it up with its correct description. Move the answers to the correct boxes, with the terms on the left side and their definitions on the right side.

• Transport proteins

• Active transport

• Active transport

• Transport proteins

• Molecules or ions

• Molecules or ions

• ATP

• ATP

Match the biological terms with their correct definitions:

• These span the cell membrane and provide a pathway for ions or molecules to move through.

• Ions or Molecules

• This is the source of energy that drives active transport.

• Concentration Gradient

• In active transport, this is what is moved across the cell membrane using transport proteins.

• ATP

• The green dots represent the flow of molecules across the membrane from an area of low to high concentration.

• Transport Proteins

Scientists learned that some tropical trees grew more slowly in warm years than they did during cooler years. They also learned that plant respiration could increase at higher temperatures. These findings are most likely to be of concern to a scientist researching and monitoring –

• the level of carbon dioxide in the atmosphere

• the number of species in a tropical rainforest

• the concentration of ozone in the atmosphere

• the amount of pollutants in rainforest soils

Identify the structures and processes at T in the diagram.

• mitochondria

• chloroplast

• respiration

• photosynthesis

Rennin is an enzyme that catalyzes a reaction that solidifies milk. Rennin was added to three different test tubes with milk. Each test tube was placed in a water bath for ten minutes. The data collected during the experiment are shown. Test Tube | Variable | Result 1 | Cold water bath | Few solids present in the liquid milk 2 | Room-temperature water bath | Semi-solid milk 3 | Hot water bath | No solids, only liquid milk Which statement best explains the result of test tube 3?

• The enzyme changed the product.

• The substrate was used up.

• The enzyme was denatured.

Fill in the blank: The substrate _______ with the enzyme.

• reacted

• dissolved

• evaporated

• condensed

The diagram represents a cellular process. Which molecule is a direct product of this cellular process?

• Glucose

• Phospholipid

• Insulin

The diagram below represents the process of exocytosis. Which portion of the diagram can best be described as the release of a foreign particle to the outside of the cell?

The diagram below represents the process of active transport. Click the portion of the diagram that provides the energy to power this process.

Which statement best describes the role of the cell membrane in this model?

• A. The cell membrane is an impermeable barrier that prevents water from entering the cell.

• B. The cell membrane allows solutes to enter the cell, which causes the cell to shrink.

• C. The cell membrane allows water to enter and leave the cell.

• D. The cell membrane removes solutes from the environment.
