What is the primary function of Adenosine triphosphate (ATP) in cells?

• To store genetic information

• To store and release energy

• To provide structural support

• To transport oxygen

Cells ______ energy by adding a phosphate group to adenosine diphosphate (ADP) molecules.

• store

• release

• consume

• waste

What are the components of Adenosine Triphosphate (ATP)?

• A) Adenine, ribose, and two phosphate groups

• B) Adenine, ribose, and three phosphate groups

• C) Adenine, glucose, and three phosphate groups

• D) Adenine, ribose, and four phosphate groups

Adenosine Triphosphate (ATP) is crucial for cells because it helps them to store and ______ energy.

• absorb

• release

• create

• destroy

What are the components of Adenosine Diphosphate (ADP)?

• A) Adenine, ribose, and three phosphate groups

• B) Adenine, ribose, and two phosphate groups

• C) Adenine, glucose, and two phosphate groups

• D) Adenine, glucose, and three phosphate groups

Adenosine Diphosphate (ADP) consists of adenine, ribose, and how many phosphate groups? Fill in the blank: ADP has ______ phosphate groups.

• One

• Two

• Three

• Four

What happens when a cell has energy available?

• It stores large amounts of energy.

• It stores small amounts of energy by adding phosphate groups to ADP molecules, producing ATP.

• It releases energy by removing phosphate groups from ATP molecules.

• It converts ADP directly into glucose.

Fill in the blank: ADP is like a _______ that needs to be recharged.

• fully charged battery

• low battery

• solar panel

• generator
