Cell Transport and Osmosis Concepts

The video covers cell transport mechanisms, including passive and active transport. Passive transport involves diffusion, facilitated diffusion, and osmosis, which do not require energy. Active transport requires energy and includes processes like endocytosis and exocytosis. The video also discusses cell metabolism, highlighting anabolism and catabolism.

What is the main difference between passive and active transport?

• Neither requires energy.

• Both require energy but in different amounts.

• Active transport requires energy, while passive transport does not.

• Passive transport requires energy, while active transport does not.

Which of the following is an example of passive transport?

• Exocytosis

• Endocytosis

• Diffusion

• Active transport

What factor does NOT affect the rate of diffusion?

• Temperature

• Pressure

• Color of the particles

• Size of the particles

What is osmosis specifically the diffusion of?

• Water

• Oxygen

• Carbon dioxide

• Proteins

In a hypertonic solution, what happens to a cell?

• It bursts

• It swells

• It shrinks

• It remains the same

What is the role of osmoregulation in fish living in saltwater?

• To increase salt concentration in their bodies

• To increase energy production

• To maintain water balance

• To decrease water intake

Which process involves the cell taking in large molecules by forming a vacuole?

• Exocytosis

• Facilitated diffusion

• Endocytosis

• Osmosis

What is the primary function of transport proteins in active transport?

• To move solutes from high to low concentration

• To facilitate osmosis

• To move solutes from low to high concentration

• To break down molecules

What is an example of an anabolic process?

• Cellular respiration

• Photosynthesis

• Diffusion

• Osmosis

What happens during catabolism?

• Large molecules are built from small ones

• Energy is stored

• Large molecules are broken down into smaller ones

• No energy is released
