Energy Flow Concepts 1&2 Review: Enzymes & ATP

Front

What is an enzyme?

Back

A protein that acts as a catalyst to speed up chemical reactions in biological processes.

Front

What is the active site of an enzyme?

Back

The specific region of an enzyme where the substrate binds and the reaction occurs.

Front

Why can't maltase catalyze the breakdown of lactose?

Back

Because maltase has a specifically shaped active site that only fits maltose, not lactose.

Front

What is the role of enzymes in chemical reactions?

Back

Enzymes lower the activation energy required for a reaction, allowing it to occur more quickly.

Front

What does it mean for an enzyme to be recyclable?

Back

An enzyme can be used multiple times to catalyze reactions without being consumed in the process.

Front

What is the difference between a substrate and an enzyme?

Back

A substrate is the reactant that an enzyme acts upon, while the enzyme is the catalyst that facilitates the reaction.

Front

What is ATP?

Back

Adenosine triphosphate, a molecule that stores and transfers energy within cells.

Front

Where is ATP produced in the cell?

Back

ATP is produced in the mitochondria during cellular respiration.

Front

What is the process of cellular respiration?

Back

A series of metabolic reactions that convert biochemical energy from nutrients into ATP.

Front

What is the significance of ATP in living organisms?

Back

ATP serves as the primary energy currency of the cell, powering various cellular processes.
