c. a sugar called glucose, a molecule called adenine, and a chain of three phosphate groups.
d. a sugar called ribose, a molecule called cytosine, and a chain of three phosphate groups.
question #2
how is atp like a battery?
a. atp is found in all living things.
b. atp is a small molecule that stores energy.
c. atp can be recharged by adding a phosphate group back to adp.
d. atp powers all the processes that keep us going.
question #3
where does a cell get the energy to make atp?
a. from the nucleus of the cell.
b. from sunlight.
c. from the environment.
d. from breaking down food like carbohydrates, fats, and proteins.
question #4
what is the main function of atp in a cell?
a. to store genetic information.
b. to provide structure and support.
c. to transport materials within the cell.
d. to provide energy for cellular processes.
question #5
what happens to atp when a cell needs energy?
a. it breaks down into adp and releases energy.
b. it combines with adp to create more atp.
c. it is stored in the cells nucleus.
d. it is used to build new proteins.
question #6
how is atp like a compressed spring?
a. it can be stretched and released to store energy.
b. it is made of a coiled structure.
c. it stores energy in the bonds between its phosphate groups.
d. it is found in the cells spring - like structures.

Explanation:

Question #1: ATP structure includes ribose (sugar), adenine (nitrogenous base), and three phosphate groups.
Question #2: Batteries store energy and can be recharged; ATP stores energy and recharges by adding phosphate to ADP.
Question #3: Cells get ATP energy by breaking down organic molecules (carbohydrates, fats, proteins) via cellular respiration.
Question #4: ATP's primary role is to supply energy for cellular activities.
Question #5: When energy is needed, ATP hydrolyzes into ADP and inorganic phosphate, releasing energy.
Question #6: A compressed spring stores potential energy; ATP stores energy in high-energy phosphate bonds.

Answer:

Question #1: B. A sugar called ribose, a molecule called adenine, and a chain of three phosphate groups.
Question #2: C. ATP can be recharged by adding a phosphate group back to ADP.
Question #3: D. From breaking down food like carbohydrates, fats, and proteins.
Question #4: D. To provide energy for cellular processes.
Question #5: A. It breaks down into ADP and releases energy.
Question #6: C. It stores energy in the bonds between its phosphate groups.
