Cellular Transport Exam

Organize these options into the right categories

Groups:

(a) Passive Transport

,

(b) Active Transport

• High to Low

• ATP (Energy)

• Against the concentration gradient

• Low to High

• Go with the flow

• With Concentration gradient

Complete the statement below regarding types of passive transport.

Passive transport is represented in three different forms. ​ (a)   is the movement of water across a semipermeable membrane. ​ (b)   , like when someone sprays perfume, is the movement of molecules down or under a concentration gradient. ​ (c)   is the movement of molecules down a gradient with the help of special protein channels.

• Osmosis
• Diffusion
• Facilitated Diffusion
• Active Transport
• Endocytosis

A student is brainstorming real-life situations that model the process of active transport.

Which of these would be effective ways to demonstrate that process? Select TWO correct answers.

• Air is released from a bicycle tire.

• A cyclist rides uphill.

• A plant absorbs nutrients from the soil to achieve growth.

• A cyclist coasts downhill without pedaling.

• A plant loses water to dehydration on a hot day.

A few drops of Lugol's iodine solution placed in a beaker of water will turn the water red. A white starch solution was poured into a length of dialysis tubing and the ends were tied. The tubing was then dropped into the beaker of iodine solution. After 10 minutes, the white starch solution turned black, and the iodine water remained red.

Why is the iodine able to go into the tubing, but the starch is not able to fall out of the tubing?

• The tubing is permeable.

• The starch is less dense than the iodine solution.

• The tubing is semipermeable.

• The iodine caused a chemical reaction that allowed it to enter the tubing.
