Homeostasis EOC Review

Homeostasis mechanisms...

• keep everything exactly the same.

• usually operate by positive feedback systems.

• act to keep the internal environmental conditions outside the normal range

• is the ability to maintain a relatively stable internal environment

What is cell transport?

• Cells moving throughout the body.

• The movement of materials in and out of cells.

• Deterioration of cells over time

• Cell differentiation or specialization

What term means a state of stability or equilibrium?

• Taxis

• Cell Transport

• Diffusion

• Homeostasis

Which cell structure is responsible for maintaining homeostasis by allowing materials in and out of the cell?

• Nucleus

• Ribosomes

• Cell Membrane

• Cell Wall

What are the 2 types of cell transport?

• Active

• Passive

• Osmosis

• Diffusion

Passive transport moves materials along the concentration gradient from:

• High to low concentration

• Low to high concentration

What are the 2 types of passive transport?

• Osmosis

• Active Transport

• Diffusion

• Homeostasis

Diffusion is the movement of:

• Water

• Gas

• Solids

• Any particles

Osmosis is specifically the diffusion of:

• Water

• Gas

• Solids

• Any particles

Active transport requires the most direct use of:

• ATP

• Proteins

• Water

• Glucose
