300

Organelle responsible for intracellular digestion.

What are lysosomes?

400

Atoms that gain or lose electrons become these charged particles.

What are ions?

400

This type of reaction builds larger molecules from smaller ones.

What is a synthesis reaction?

400

These molecules act as enzymes and control reactions in the bo

What are proteins?

400

The sodium-potassium pump is an example of this type of transport.

What is primary active transport?

400

Network that gives the cell shape and allows movement of materials.

What is the cytoskeleton?

500

Highly reactive molecules with unpaired electrons that can damage cells.

What are free radicals?

500

The movement of water across a selectively permeable membrane.

What is osmosis?

500

This process breaks polymers into monomers using water.

What is hydrolysis?

500

A highly selective process where molecules bind to receptors before entering the cell.

What is receptor-mediated endocytosis?

500

Organelle where ribosomes are produced.

What is the nucleolus?
