Cell Processes: Homeostasis

Which biomolecule is used to transport large molecules across the cell membrane?

• Lipids

• Proteins

• Carbohydrates

• Nucleic Acids

What is the function of proteins in the cell membrane?

• Facilitate the movement of particles

• Receive chemical signals

• Code for specific structures

• Create a hydrophobic layer

Which biomolecule surrounds all cells and separates the outside from the inside?

• Lipids

• Proteins

• Carbohydrates

• Nucleic acids

What is the function of the cell membrane?

• Energy conversions and synthesis of new molecules

• Synthesis of new molecules and homeostasis

• Transport of molecules and energy conversions

• Homeostasis and transport of molecules

Which of the following is a true statement?

• The cell membrane is an impermeable barrier.

• The cell membrane allows solutes to enter the cell.

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

• The cell membrane removes solutes form the environment.

How does the cell membrane help maintain homeostasis?

• By providing a circular structure for all cells

• By making proteins to provide the cell with energy

• By regulating the transport in and out of the cell

• By storing food as a future energy for the cell

What best describes the transport process of the Sodium Potassium pump?

• Energy is used to move ions from low to high concentration

• Energy is used to move ions from high to low concentration

• Ions are moving from high to low without energy

• Ions are moving from low to high without energy

Passive Transport includes

• osmosis and facilitated diffusion

• Facilitated diffusion and exosytosis

• Exocytosis and Endocytosis

• Diffusion and endocytosis

Active transport includes

• osmosis and facilitated diffusion

• facilitated diffusion and exocytosis

• endocytosis and exocytosis

• diffusion and endocytosis

Endocytosis is a type of transport in which

• Large molecules are brought in & the membrane forms a vacuole around them

• Membrane proteins move molecules & bring the cell closer to equilibrium

• Oxygen transfers into red blood cells through gaps

• Water moves across the membrane from high to low
