What is the main purpose of cell communication and signaling?

• To move molecules

• To coordinate cell activities

• To produce ATP

• To store nutrients

Which type of signaling involves communication within the same cell?

• Intercellular

• Intracellular

• Paracrine

• Endocrine

In paracrine signaling, signals act on:

• The same cell

• Nearby cells

• Distant cells

• All cells in the body

Endocrine signaling uses which system to send signals?

• Nervous system

• Circulatory system

• Respiratory system

• Digestive system

What molecule binds to a receptor to deliver a signal?

• Ion

• Enzyme

• Ligand

• Hormone only

Which process moves molecules from high to low concentration without energy?

• Active transport

• Diffusion

• Endocytosis

• Exocytosis

Osmosis specifically involves the movement of:

• Glucose

• Sodium

• Water

• Proteins

Facilitated diffusion requires:

• Energy (ATP)

• Transport proteins

• Vesicles

• Enzymes

The sodium-potassium pump is important for:

• Photosynthesis

• Muscle contraction and nerve impulses

• Protein synthesis

• Cell division

Which process allows cells to expel materials in vesicles?

• Endocytosis
