Unit 3: Enzymes, ATP, and Energy Flow

Front

What is an enzyme?

Back

A biological catalyst that speeds up chemical reactions in living organisms.

Front

What does ATP stand for?

Back

Adenosine Triphosphate, the energy currency of the cell.

Front

What is the role of ADP in energy transfer?

Back

ADP (Adenosine Diphosphate) is formed when ATP loses a phosphate group, releasing energy for cellular processes.

Front

Define primary consumer.

Back

An organism that eats producers (plants) in a food chain, typically herbivores.

Front

What are reactants in a chemical reaction?

Back

Substances that undergo change during a chemical reaction.

Front

What are products in a chemical reaction?

Back

Substances that are produced as a result of a chemical reaction.

Front

Explain the specificity of enzymes.

Back

Enzymes are specific, meaning each enzyme only catalyzes a reaction for a particular substrate.

Front

What is a food chain?

Back

A linear sequence of organisms through which nutrients and energy pass as one organism eats another.

Front

What is a food web?

Back

A complex network of interconnected food chains in an ecosystem.

Front

What is the difference between herbivores and carnivores?

Back

Herbivores eat plants, while carnivores eat other animals.
