What does the acronym "ATP" stand for?

Adenosine Triphosphate

100

What does the acronym "ADP" stand for?

Adenosine Diphosphate

100

How often does the ATP cycle operate within living cells?

It is constant in cells

100

Which molecule is used by the cell specifically for energy storage?

Glucose

200

What happens to molecules during metabolic reactions to release energy?

They are broken down or spent

200

How many phosphate groups are contained in one ATP molecule?

3 phosphate groups

200

What event causes ATP to convert into ADP?

One of the phosphate groups breaks off

200

What provides the required energy to form ATP from ADP?

Food

200

Is ATP better suited for energy transfer or energy storage?

Energy transfer[2]


300

What is the term for all chemical reactions in a cell that handle energy molecules?

Metabolism

300

What is the nitrogenous base found in an ATP molecule?

Adenine

300

What general process moves a phosphate group between molecules to transfer energy?

Phosphorylation

300

What compound is recycled back into ATP when energy from food is supplied?

ADP (Adenosine Diphosphate

300

In the monetary analogy, which molecule represents dollars for immediate transactions?

ATP

400

Why must cells continually undergo metabolic reactions?

To break down or spend molecules to get energy

400

What type of sugar molecule forms the core structure of ATP?

Ribose

400

What specific group moves between molecules during phosphorylation?

A phosphate group

400

What continuous cellular cycle connects ADP back into ATP using food energy?

The ATP Cycle

400

In the monetary analogy, which molecule represents stored wealth like gold?

Glucose

500

What two actions on molecules define metabolism in the notes?

Breakdown or spending of molecules for energy

500

What are the three structural components of an ATP molecule?

Adenine (nitrogenous base), ribose (sugar), and 3 phosphate groups

500

Describe how phosphorylation transfers energy in the cell.

A phosphate group moves between molecules[2]


500

How does energy from food contribute to maintaining cellular work via the ATP cycle?

Food provides the energy needed to re-attach a phosphate group to ADP to recreate ATP

500

Explain the gold and dollar analogy regarding cellular energy.

Glucose acts like gold (dense, stored energy), while ATP acts like dollars (easily spent/transferred energy)
