Cell Structure and Function

What is the role of the plasma membrane in secretion?

• Stores secretions
• Generates ATP
• Synthesizes hormones
• Transports molecules out of the cell via vesicles

What is the result of increased membrane fluidity at low temperatures?

• Membrane becomes leaky
• Membrane ruptures
• Membrane shrinks
• Membrane remains functional

What is the function of the plasma membrane in signal transduction?

• Generates ATP
• Stores genetic information
• Synthesizes lipids
• Receives and relays signals to the cell interior

What is the role of aquaporins in the cell membrane?

• Transport ions
• Synthesize ATP
• Produce proteins
• Facilitate the movement of water across the membrane

What is the main difference between pinocytosis and phagocytosis?

• Speed of the process
• Energy required
• Location in the cell
• Type of material taken in
