Front

Which macromolecule can form structural parts of the cell, act as enzymes, or be involved in cell movement?

Back

Proteins

Front

How do organisms manage to grow, reproduce, and maintain their internal organization?

Back

Organisms exchange matter with the environment, taking in nutrients and releasing waste products.

Front

What are the four main types of biological macromolecules?

Back

Carbohydrates, lipids, proteins, nucleic acids.

Front

What is the primary function of carbohydrates in living organisms?

Back

To provide energy and serve as structural components.

Front

What is the role of proteins in biological systems?

Back

Proteins serve as enzymes, structural components, and play roles in cell signaling and transport.

Front

What is the structure of a phospholipid?

Back

A phospholipid consists of a hydrophilic (water-attracting) head and two hydrophobic (water-repelling) tails.

Front

What is a polar covalent bond?

Back

A type of bond where electrons are shared unequally between atoms, resulting in partial charges.
