Unit 3 Energy Flow Concepts 1 & 2

Front

What are the components of an ATP molecule?

Back

An ATP molecule is made up of adenine, ribose (a sugar), and three phosphate groups.

Front

How is energy released from an ATP molecule?

Back

Energy is released from an ATP molecule when it loses a phosphate group, converting it to ADP (adenosine diphosphate).

Front

What is the term for the molecule that an enzyme binds to?

Back

The molecule that an enzyme binds to is known as its substrate.

Front

What components make up an ADP molecule?

Back

An ADP molecule consists of adenine, ribose, and two phosphate groups.

Front

What characterizes an exothermic chemical reaction?

Back

An exothermic chemical reaction releases more energy than it absorbs.

Front

What is the role of ATP in cellular processes?

Back

ATP serves as the primary energy carrier in cells, providing energy for various biochemical reactions.

Front

What happens to ATP during cellular respiration?

Back

During cellular respiration, ATP is produced from ADP and inorganic phosphate through the process of phosphorylation.

Front

What is the difference between ATP and ADP?

Back

ATP (adenosine triphosphate) has three phosphate groups, while ADP (adenosine diphosphate) has two phosphate groups.

Front

What is a substrate in the context of enzyme activity?

Back

A substrate is the specific reactant that an enzyme acts upon during a biochemical reaction.

Front

What is the active site of an enzyme?

Back

The active site of an enzyme is the region where substrate molecules bind and undergo a chemical reaction.
