Massive Biology EOC Review

Front

What is a monomer?

Back

A monomer is a small molecular fragment that can join together with other monomers to form larger molecules called polymers.

Front

Define niche in an ecosystem.

Back

A niche is the role and position of an organism in its environment, including its habitat, resource use, and interactions with other organisms.

Front

What is a stimulus in biology?

Back

A stimulus is a change in the environment that affects the activity of an organism.

Front

What macromolecule provides structural support and acts as enzymes?

Back

Proteins provide structural support and act as enzymes to catalyze metabolic reactions.

Front

Why is the active site of an enzyme important?

Back

The active site of an enzyme is important because it allows the enzyme to catalyze very specific reactions by interacting with specific substrates.

Front

What are carbohydrates?

Back

Carbohydrates are macromolecules made up of sugar molecules that provide energy and structural support in living organisms.

Front

Define polymer.

Back

A polymer is a large molecule made up of repeating units called monomers.

Front

What is the function of lipids in biological systems?

Back

Lipids serve as long-term energy storage, make up cell membranes, and act as signaling molecules.

Front

What is homeostasis?

Back

Homeostasis is the maintenance of a stable internal environment in an organism despite changes in external conditions.

Front

What is the role of enzymes in biological reactions?

Back

Enzymes act as catalysts that speed up chemical reactions in biological systems by lowering the activation energy.
