Unit 3 - Cell Energy & Transport Concept Review

Create an analogy for transport across the cell membrane.

• A door allowing people in and out of a room

• A wall blocking all movement

• A sponge soaking up water

• A waterfall flowing in one direction

What is the result of diffusion across a membrane?

• Equal concentration on both sides

• No change in concentration

• Higher concentration inside the membrane

• Higher concentration outside the membrane

Describe the advantage of a cell wall during osmosis.

• It allows cells to absorb nutrients more efficiently.

• It prevents the cell from bursting due to excess water intake.

• It increases the speed of osmosis.

• It makes the cell impermeable to water.

What happens to an animal cell when placed in a hypotonic solution ?

• It will shrivel

• It will stay the same

• It will swell and burst

Name three types of active transport.

• Osmosis, Diffusion, Facilitated diffusion

• Primary active transport, Secondary active transport, Osmosis

• Primary active transport, Secondary active transport, Facilitated diffusion

• Endocytosis, Exocytosis, Transport pump

What is required from the cell for active transport to occur?

• ATP

• DNA replication

• Passive transport mechanisms

• Osmosis

Which of the following statements correctly describes the movement of particles in passive and active transport?

• In passive transport, particles move from a low concentration area to a high concentration area without energy, while in active transport, particles move from a high concentration area to a low concentration area with energy.

• In passive transport, particles move from a high concentration area to a low concentration area without energy, while in active transport, particles move from a low concentration area to a high concentration area with energy.

• In passive transport, particles do not move, while in active transport, particles move from a low concentration area to a high concentration area with energy.

• Both passive and active transport require energy to move particles from a low concentration area to a high concentration area.

What is the main goal of cell transport?

• To communicate with other cells

• To maintain homeostasis by regulating the movement of substances

• To produce energy for cellular activities

• To replicate genetic material

Explain the process of energy transfer in the ATP—ADP cycle.

• Energy transfer in the ATP—ADP cycle occurs through photosynthesis
• Energy transfer in the ATP—ADP cycle occurs through the process of osmosis
• Energy transfer in the ATP—ADP cycle occurs through the hydrolysis of ATP, releasing a phosphate group to form ADP and releasing energy.
• Energy transfer in the ATP—ADP cycle occurs through the combustion of glucose

What are the reactants for photosynthesis, and what will happen to the rate of photosynthesis if they are limited?

• Carbon dioxide and water; the rate will decrease

• Oxygen and glucose; the rate will increase

• Carbon dioxide and oxygen; the rate will not change

• Water and glucose; the rate will decrease
